How the International Weed Genomics Consortium is Helping Advance the Field of Weed Science into the Era of Genomics
Authors: Montgomery Jacob S. , Gaines Todd A.
Published: September 2024

The development and use of genomic resources has accelerated the advancement of agricultural production over the past several decades. Until recently, development of these resources for weed species lagged compared to other fields. Understanding the sequence and order of weed genomes
unlocks the potential for research approaches to identify the genetic basis of important traits like herbicide resistance and abiotic stress tolerance. Knowledge around such traits can inform the development of more productive crops and further our understanding of adaptation mechanisms. Comparison
of reference genome assemblies for many weed species also promises to improve weed management through characterization of new herbicide target sites and development of next generation weed control methods. Here, we briefly discuss the history of genomics in weed science and discuss the formation
and current outcomes of the International Weed Genomics Consortium, a collaborative group of researchers working to make genomic resources for weed species accessible and usable to the research community. We finish with a forward looking discussion of the direction of genomics in weed science
and possible uses of the resources that have recently been developed.
Need for Digitalizing Integrated Pest Management for Future
Authors: Dhang Partho
Published: September 2024

Urban IPM is the mainstay for keeping sensitive premises free of pests and pesticides on a longer term. Food and beverage industry is one sector who have successfully implemented IPM in a global scale. Its continuity and expansion over years is also a strong indicator of the program’s
sustainability and success. However, in other sectors IPM adoption is slow. Urban IPM will become common if it principally addresses sustainability through manageability and adaptability. It has to move from a doctrine into a pragmatic user-friendly concept. Digitalization is one direction
where all elements involved in IPM can be simplified, collected without disruption, made accurate and communicable. Adopting a digitalized IPM, will help provide larger coverage, access inaccessible areas, help round the clock monitoring, generate programmable data, maintain communication
and determine action. The data will not only address pest issues, but also something beyond, such as look into human sensitivities, structural improvements, economics, and environmental concerns together. In this way IPM will direct pest control towards a “green” direction.

The Number and Social Composition of Yekaterinburg Residents According to the 1728 and 1788 Censuses
Authors: Borodina Elena , Tsemenkova Svetlana
Published: September 2024

This article studies the history of the population of Yekaterinburg in the eighteenth century. Despite the large number of works on the history of the city, its inhabitants have rarely been the subject of individual comprehensive studies. For the first time the authors conduct a comparative analysis of two household censuses of Yekaterinburg in 1728 and 1788, the materials of which are stored in the funds of the Russian State Archive of Ancient Acts and the State Archive of Sverdlovsk region. The aim of the work is to study the development of the composition and number of the population of Yekaterinburg during the first 65 years of the city’s existence. The methods of the work are quantitative research, study of primary sources, historical and comparative analysis. The comparison of these primary sources helps to identify the main social groups of Yekaterinburg in the 1720s and 1780s. Based on the data obtained, it can be concluded that the main groups of the population in the period in question were craftsmen and workers, military personnel, schoolchildren, clerks, and heads of mining and civil administration. There is a noticeable increase in the number of people engaged in crafts and trades. It is noteworthy that craftsmen, labourers and common soldiers, as well as women and children, gradually appeared among the craftsmen. In the late 1780s, the number of widows, soldiers’ wives and recruits increased. At the same time, groups such as recruits, landless peasants, their children and wives gradually disappeared from the structure of the urban community. The proportion of merchants and townspeople increased. There were many retired artisans, labourers, soldiers and clerks. In addition, many almsmen had registered in the city. All these changes indicate the transitional nature of Yekaterinburg society, which was gradually changing from a mining centre to a city of trade and crafts.
A Parodic Legend about an Ancestor of the Zagryazhskys’ in the Circle of Genealogical Pasquils of the 17th Century
Authors: Khoruzhenko Oleg
Published: September 2024

This article examines the origin and genre of the parody legend of Isakhara/Sahara, the Horde prince (“an honourable man of royal descent”), an ancestor of the Zagryazhskys’. Only one copy of it survives today – its text was inscribed on blank leaves of an early seventeenth-century manuscript. As far as can be judged, this legend was not widely circulated in the manuscript tradition; no direct quotations, reminiscences or allusions have been found to indicate familiarity with it. It is assumed that the text in question is a parody of the Zagryazhskys’ genealogical legend, as it is presented in the genealogical record submitted by this family to the Chamber of Genealogical Affairs of the Order-in-Charge of Prikaz on 5 June 1686. With the introduction of several interpolations, the genealogical legend was transformed into a kind of historical anecdote, all the characters of which began to appear either pitiful or unpleasant. Both the dating of the text in question (end of the seventeenth century) and its content suggest that it could not have appeared in the proceedings of the mestnichestvo; its author was not guided by the practical purpose of the mestnichestvo, but by the motivation of a writer prone to social satire. This distinguishes the text under consideration from the line of genealogical pasquils generated by the principles of mestnichestvo of service organisation and allows to take a new look at the genesis of the genre of historical anecdote, the emergence of which in Russia is attributed by researchers only to the Catherinian era.
Categorical-textual Analysis of a Speech Work: Rationale and Application of the Method
Authors: Matveeva Tamara
Published: September 2024

This article describes a method of text analysis by means of linguistic characterisation of text categories. Primarily, the author discusses the problem of the object of study and the correlation between the concepts of ‘text’, ‘functional style’, ‘genre’. As a result, genre as a type of text and a carrier of generic characteristics of its functional style is regarded as the object. Text categories are considered as speech sets (compositions of linguistic means) present in the text and functioning as its components. Each of the categories is distinguished based on the common semantic function of the linguistic means that form it. The text category as a functional-semantic unit is an organised linguistic set whose full characteristics are three-aspect in nature, i. e. it includes a paradigmatic (system-linguistic), a syntagmatic (speech) and a compositional (textual) description. Text categories are interpreted as linguistic compositions with typical features of selection, combinatorics and arrangement of components. This approach implies a broadening of the units of text analysis, moving from atomic units to complex structural formations involved in modelling the whole text. The method is demonstrated on complete texts of various functional styles of the Russian literary language (journalistic, scientific, official, artistic) and genres (memorandum, summary of a report, article of law, lyrical miniature). For the purpose of demonstration, the author selects the categories of theme, chronotope and tonality and demonstrates their functional, stylistic and genre variations. The categorical-text method is suitable for making intertextual comparisons, including determining textual differences between groups of speech works. The technology of textual analysis under consideration is based on linguistic and speech taxonomy and remains fundamentally linguistic.
The Category of Tonality in Peripheral Genres of Business Communication
Authors: Shirinkina Mariya
Published: September 2024

This article analyses peripheral genres of business communication in terms of the category of tonality. The aim of the study is to describe the characteristics of the expression of tonality in the messages of the executive authorities in the mass communication media. The article refers to the posts published in three official accounts of public administration bodies in the social network “VKontakte” (Ministry of Health of the Russian Federation, Ministry of Health of Perm Krai, Ministry of Health of Sverdlovsk Region) between 1 June and 31 August 2023; in total, about 1000 poly-code communication products. The novelty of the study lies in the application of the categorical-textual approach to the analysis of stylistically hybrid (located at the intersection of official-business, journalistic and colloquial functional styles) poly-code speech products. The author determines the field composition and communicative content of the tonality category in peripheral genres of business communication. In particular, it is shown that 1) the subfield of expression of will is represented by micro-subfields of recommendation, desire and information; 2) the subfield of emotional evaluation is formed by micro-subfields of implicit evaluation and explicit evaluation; 3) the subfield of intensity is not segmented and is realised by linguistic markers of other subfields and semantically expresses a low degree of categorical expression of will in publications of executive bodies and a high level of emotionality of these texts. Taking into account the results of the automatic analysis of the messages by the functionality of the Popsters.ru service, the article reveals the preferred and undesirable tonal variants of certain language products for the users (on the one hand, tonal meanings in the messages that received the greatest response from the subscribers, and on the other – in the messages that did not cause a reaction of the addressee). A high coefficient of user engagement is observed for posts that implement an individual approach to subscribers and express the concern of representatives of the Ministry of Health for the health of citizens. User engagement is low for posts in the form of press releases, which are characterised by a high degree of officialism. In conclusion, the author emphasises the need to abandon the formalised official style of communication in favour of a personalised and relaxed form, which corresponds to the nature of communication in social networks.
Personal Contacts of Bishops and Representatives of the Political Elite in 16th-Century Russia
Authors: Usachev Andrey
Published: September 2024

This article deals with an important but hitherto unexplored issue – the personal contacts of Russian church leaders with representatives of the political elite. So far, the study of this issue has been limited to the enumeration of donations to monasteries. This article shows that some church leaders (the Bishop of Novgorod (1526–1542), Metropolitan (1542–1563) Makarii, the Archbishop of Novgorod Feodosii (1542–1551) and perhaps others) established and supported contacts with influential laymen (princes Shuisky, Obolensky, Rostovsky, Bulgakov, with the Morozovs, Sheins, etc.). These relations were facilitated by the existence of a dual system of local government – secular and ecclesiastical. In some cases, the bishops established relations with the governors and voivods sent annually from Moscow. These contacts did not cease when they returned to the capital: the bishops corresponded with them and sent them gifts. This collaboration was mutually beneficial. On the one hand, the bishops were supported by influential people in Moscow. This was especially necessary during periods of instability (the childhood of Ivan IV, the reign of Fyodor Ivanovich), when the princes Shuisky and Godunov were able to influence appointments in the Church. Relations with representatives of the nobility expanded the administrative possibilities of the bishops when it was necessary to defend the interests of the diocese. For example, they allowed the Archbishop of Novgorod to relieve the representatives of the service class of the burdensome service on the southern frontiers. On the other hand, the attention of the church leaders, who had immense authority in the Middle Ages, could flatter the members of the Royal Council (Duma). The ecclesiastical elite could both provide moral support in the event of the death of relatives and petition the court for aristocrats who were guilty in the eyes of the government. The study is based on chronicle and legal sources, records of church art objects, the book of expenses of the House of St Sophia for the years 1547–1548. The author applies the methods of historical source study, which help to reconstruct the picture of the past from fragmentary and contradictory evidence.
Ural Archaeography Today: Research Issues
Authors: Pochinskaia Irina
Published: September 2024

In 2024, the Ural Archaeographic Centre, which exists at the Faculty of History of UrFU, is to celebrate its 50th anniversary. It began with the organisation of archaeographic expeditions and the creation of the Laboratory of Archaeographic Studies to conduct these expeditions, store, and study the collected works of Cyrillic writing. The activities of the laboratory laid the foundation for the creation of the Ural School of Archaeography. Many generations of students have passed through it, acquiring additional knowledge beyond the limits of university curricula. Some of these students have turned academic work into their profession. The expedition ceased to operate in 2003 due to changes in the social situation, but the laboratory continued its activities, focusing on the study of the fund of book artefacts of the Cyrillic tradition, collected over 30 years of fieldwork and comprising some 6,000 items. Currently, the LAS is a research, scholarly, methodological, and educational centre in the field of archaeography and, more broadly, the history of traditional spiritual culture of Russians, paying special attention to its Ural specificity. In connection with the anniversary, this article provides an overview of the main areas of scholarly research and the most significant publications of the LAS team over ten years, from 2013 to 2023. The main source base for the research of the LAS staff is its own fund of works in Cyrillic script. The publications are divided into two blocks. One of them includes studies of handwritten heritage, including multidimensional analysis and publication of manuscripts, study of the history of Cyrillic book printing, and scholarly description of funds. The other includes studies of the history and culture of the Old Believers as guardians and successors of the ancient Russian book tradition in modern and contemporary times.
Politização na Fazenda: os efeitos das crises políticas e econômicas na rotatividade dos DAS
Authors: Olivieri Cecília , Almendra Lucas
Published: September 2024

Resumo Este trabalho analisa a rotatividade dos ocupantes de cargos de Direção e Assessoramento Superior (DAS) 4 a 6 de secretarias do Ministério da Fazenda entre 1996 e 2020. O referencial teórico são os estudos sobre a politização da burocracia estatal de alto escalão. Os dados analisados indicam que há disparidade entre a taxa de rotatividade dos ministros da Fazenda (que é baixa) e a taxa de rotatividade dos ocupantes dos cargos de DAS (que é alta). O objetivo do texto é explorar explicações para essa diferença, considerando as características distintivas desse ministério em relação aos demais: ele é mais insulado e o perfil de seu pessoal é mais técnico, e sua área de atuação (gestão fiscal e econômica) afeta interesses de grupos específicos da sociedade, os agentes do mercado privado. Os resultados indicam que as crises político-econômicas são fatores importantes na rotatividade dos DAS ao lado de turnovers presidenciais e ministeriais. A politização da burocracia de alto escalão do Ministério da Fazenda não seria tão forte quanto apontado pela literatura, mas se caracterizaria pela preservação do ministro às custas de sua equipe, cujos membros são alterados como resposta a crises de ordem política e geradas por instabilidades econômicas nacionais e internacionais.
Politicization on Finance Ministry: the effects of political and economic crises on the turnover of civil servants in senior management and advisory positions
Authors: Olivieri Cecília , Almendra Lucas
Published: September 2024

Abstract: This work analyzes the turnover of civil servants occupying senior management and advisory positions (called DAS 4, DAS 5, and DAS 6 in the Brazilian public bureaucracy) in the Ministry of Finance departments between 1996 and 2020. The theoretical reference is studies on the politicization of high-level state bureaucracy. The data analyzed indicates a disparity between the turnover rate of Finance Ministers (which is low) and the turnover rate of those occupying DAS positions (which is high). The article explores explanations for this difference, considering the distinctive characteristics of this ministry in relation to others: it is more insulated, the profile of its staff is more technical, and its area of activity (fiscal and economic management) affects the interests of specific groups in society, private market agents. The results indicate that political-economic crises are important factors in DAS turnover alongside presidential and ministerial turnovers. The politicization of the high-level bureaucracy of the Ministry of Finance is not as strong as pointed out in the literature but is characterized by the preservation of the minister at the expense of his team, whose members are changed in response to political crises and generated by national and international economic instabilities.
Recessão, inflação e dívida interna
Authors: RANGEL IGNÁCIO
Published: September 2024

RESUMO Quando a economia está em recessão, a inflação acelera na economia brasileira. Para que os preços subam durante a recessão, as corporações, em uma economia oligopolista, reduzem a produção e aumentam os preços, ao invés de fazer o contrário, como ensinam as economias convencionais. Para superar a recessão, é preciso que os empresários aproveitem as novas oportunidades de investimento em novos setores dinâmicos da economia. No Brasil, os serviços públicos são o setor que tem mais oportunidades de crescimento. As empresas privadas, nacionais e multinacionais, que já têm capacidade ociosa e excesso de poupança, irão repassar essas economias. Aos serviços públicos assim que os arranjos institucionais e financeiros o permitirem.
O proletariado como produtor e como produto
Authors: BERNARDO JOÃO
Published: September 2024

RESUMO O autor critica as teses segundo as quais a força de trabalho é produzida fora do processo de produção capitalista. No modelo que ele propõe, os salários-família cobrem tanto a produção de bens e serviços quanto a produção de força de trabalho. O proletariado considerado como insumo produz mais-valia e considerado como produto incorpora a mais-valia. O autor analisa a relação entre a força de trabalho como produto e como insumo. Ele também pretende mostrar que o papel do mercado no capitalismo é menor, e o papel do Estado é o central. Ao mudar de produto para insumo, a força de trabalho é desvalorizada pelo processo da mais-valia relativa. Por fim, analisa algumas implicações desse modelo no que diz respeito às lutas sociais.

Published: September 2024

Abstract The study of reproductive biology is an important tool in identifying protective measures to preserve fish stocks, providing essential data for a reliable management system that ensures a balance between the environment and the economy. This study aims to analyze the first sexual maturity and type of spawning of the fish Conodon nobilis (Linnaeus, 1758) on the Amazon coast, specifically in the Gulf Maranhense region. 360 specimens were obtained from commercial fishing activity in the community of Raposa-MA during the period from January to December 2021. Biometric data were recorded, and the gonadal maturation stages were determined through macro (maturation scale) and microscopic (histology) analyzes. Sex ratio, mean length of first sexual maturation and type of spawning were determined. Negative allometric growth was recorded for both sexes, indicating a greater increase in length than in weight, and the length varied from 11 to 31.8 cm and the sex ratio was 1 male:1.5 female. Individuals in all stages of maturation were observed throughout the year, with a predominance of individuals in spawning capacity and reproductive peaks in January, April and May, indicating that the species presents multiple spawning. The length at first sexual maturity (L50) for females was 18.41 cm and for males was 18.91 cm. Knowledge of the mean size at sexual maturity can help define appropriate regulations for fishing, ensuring that individuals have the opportunity to reproduce at least once before being captured.

Published: September 2024

Abstract Date palm trees, their cultivation and harvesting have become challenging due to infestations caused by some specific mites including Oligonychus afrasiaticus (McGregor) (Tetranychidae). Current research has been carried out to investigate the efficiency of nine pesticides against eggs and date palm mite, Oligonychus afrasiaticus against nine pesticides. Side effects of the nine pesticides were also examined on predatory mite, Amblyseius swirskii Athias-Henriot (Phytoseiidae). Mites and their eggs were treated with the recommended dosage of nine pesticides namely, Bifenazate 24%, Bifenthrin 10%, Matrine 0.6%, Imidacloprid 37% + Abamectin 3%, Sulphur 99.5%, Micronized Sulphur 80%, Mineral oil 95%, Pyrethrin 1.5% and Hexythiazox 10%, while they were present in their natural environment on the date palm trees in the experimental fields. Highest mortality of 91.16% was observed when O. afrasiaticus was treated with Bifenazate (24%) followed by 87.31%, 85.20%, 72.06%, 71.34%, 65.35%, 64.14%, 61.06% and 24.25% in case of Bifenthrin 10%, Matrine 0.6%, Imidacloprid 37% + Abamectin 3%, Sulphur 99.5%, Micronized Sulphur 80%, Mineral oil 95%, Pyrethrin 1.5%, and Hexythiazox 10%, respectively. A minimum hatching of 25.74% was observed when eggs of O. afrasiaticus were treated with Hexythiazox 10% and the highest success of hatching (99.07%) was seen when treatment was given with Imidacloprid 37% + Abamectin 3%. When same trials with same nine pesticides were performed on predatory mite; Amblyseius swirskii, the highest mortality in terms of percentage reduction (75.63%) was observed with Bifenthrin and the lowest (14.69%) with Matrine. Nine pesticides used in this study have distinct toxicity against targeted mite, their eggs and the predatory mite. A two steps control strategy is recommended for this treatment. First spray Hexythiazox at the egg laying stage and then at the moving stage of mites by using Matrine which is toxic to mites but negligibly toxic to predatory mites. Further studies are recommended to evaluate varied actions of the pesticide against eggs, phytophagous mites, and predatory mites.

ABSTRACT: Cattle trypanosomiasis imposes significant economic burdens on the global livestock industry. The causative agents of this disease belong to the protozoan Trypanosoma genus. This study aims to perform detection (parasitological and molecular) and genetic characterization to analyze Trypanosoma spp. in cattle from 15 municipalities in the state of Rio de Janeiro, focusing on the 18S rDNA and Cathepsin-L (CatL) gene of Trypanosoma vivax and Trypanosoma theileri. A total of 389 blood samples from 15 dairy cattle farms in the state of Rio de Janeiro were collected, and DNA was extracted for subsequent PCR amplification of Trypanosoma spp. 18S rDNA and CatL genes. The resulting amplicons underwent sequencing and alignment for phylogenetic analysis, with comparisons made to GenBank isolates. Concerning parasitological analysis, blood smears presented 4.4% of positive cattle (n=17/389) for T. vivax and did not show any trypomastigote forms of T. theileri. The absolute frequency of Trypanosoma spp. through molecular detection targeting 18S rDNA was 11.6% (45/389). However, when performing species-specific PCRs, the T. vivax frequency, determined through CatL gene PCR, was 12.8%, and the T. theileri frequency was 3.6%. Phylogenetic analysis based on 18S rDNA revealed low diversity among T. vivax sequences, suggesting potential host segregation. This study emphasizes the high frequency of positive samples by PCR when compared to direct parasitological exams. Additionally, T. vivax phylogeny targeting 18S rDNA hints at sequence clustering related to host species. Importantly, this investigation unveils, for the first time in Rio de Janeiro’s cattle, the circulation of T. theileri lineage ThI, encompassing genotypes IIB and IF. This discovery expands our understanding of this parasite’s geographical distribution and genetic diversity.
Association of nutritional status with handgrip strength in patients with chronic kidney disease
Authors: Freire Camila Pacheco , Santos Helânia Virgínia Dantas dos
Published: September 2024

ABSTRACT Objective Evaluation of handgrip strength with indicators of nutritional status in chronic kidney disease patients. Methods This is a cross-sectional, descriptive study, with an analytical approach conducted at Hospital das Clínicas de Pernambuco, Recife, Brazil, between May and September 2022. Demographic, clinical, anthropometric and biochemical variables were evaluated. Individuals, males and females, were classified with low or high handgrip strength. The upper left or right limb was assessed, based on a national reference standard. Results: A total of 81 patients of both genders were included in the investigation. Their mean age was 54.69±16.03 years. According to the muscle mass index, 12.3% and 18.7% of adult and elderly patients were classified as malnourished respectively. Regarding handgrip strength (HGS), 92.4% of the participants were classified as low handgrip strength patients. These had a higher mean age (55.81±15.91), lower mean height (1.61±0.09) and reduced arm muscle circumference (23.48±4 .24), showing a statistical significance of p=0.025; 0.045 and 0.022 respectively. Conclusion It can be concluded that low handgrip strength is associated with patients’ reduced muscle mass and older age, and it is suggested that handgrip strength can be used routinely in the clinical practice as a predictor of loss of lean mass in chronic kidney disease patients.

Published: September 2024

ABSTRACT Objective To identify preferences, motivations, and professional activities of nutritionists from the Federal Technical Schools in Brazil regarding their field of work, potentials and weaknesses, and level of job satisfaction. We also aimed to assess the relationship between the performance of professional activities and job satisfaction. Methods This is a cross-sectional study, with a quantitative approach and descriptive analysis. The nutritionists completed an online form (Google FORMS®) about identification, interpersonal aspects, professional activities, and job satisfaction. Descriptive statistics were reported for all variables. Student’s t-tests and Mann-Whitney U tests were used to assess differences in satisfaction levels among nutritionists who perform certain professional activities or not, with significance considered at No-BreakpNo-Break<0.05. Results A total of 195 nutritionists from all Brazilian states, except Acre and Amapá, participated in the study. Out of these 95.1% were female, with over 11 years graduation (43.8%), working in the institution for 1 to 5 years (51.4%), and 99.5% were public servants. Job stability in the public service motivated 70.3% nutritionists to work in the field. The majority stated they were committed (67.6%) and wished to continue in the job (27.6%). Difficulty in balancing management activities with nutrition education was the main drawback (25.4%). Satisfaction, rated at 3.61 on a scale of 1 to 5, differed significantly (p<0.05) based on the performance of professional activities. Conclusion Effective communication among those involved in the National School Feeding Program, increased participation, and autonomy in administrative decisions, along with support for their mandatory activities, can enhance the satisfaction of nutritionists in federal technical schools.

RESUMO O ceftiofur sódico ou a estreptomicina foram empregados para a terapia da leptospirose em hamsters (Mesocricetus auratus ) experimentalmente infectados com uma estirpe patogênica de L.interrogans sorovar pomona.O inóculo infectante foi ajustado para a média de 20 a 30 leptospiras por campo, aumento de 200 vezes. Na primeira etapa um grupo de animais foi tratado com uma única aplicação de estreptomicina na dose de 25mg/kg de peso vivo, via intramuscular e outro com o ceftiofur sódico em uma ou duas aplicações de 20mg/kg de peso vivo, via intramuscular. Na segunda etapa, o ceftiofur sódico foi empregado em uma única aplicação das concentrações de 30 ou 40 mg/kg de peso vivo, via intramuscular. Na terceira etapa o ceftiofur sódico foi empregado em uma única aplicação de 25mg/kg, de peso vivo, via intramuscular em hamsters inoculados com diferentes concentrações de leptospiras, série de cinco diluições geométricas de razão dez. Em todas as etapas a primeira aplicação do antibiótico foi efetuada 48 horas após o estabelecimento da infecção experimental. Os hamsters foram mantidos em observação atentando-se para a presença de sinais clínicos da leptospirose. Os que adoeceram foram sacrificados na fase agônica e a infecçào foi confirmanda através da constatação da presença de leptospiras no macerado de tecido hepático ou renal. Os animais que não apresentaram sinais clínicos foram sacrificados no 21º ou 30º dia pósinfecção, quando foi investigada a condição de portador renal de leptospiras. A técnica das diluições seriadas em meio de Fletcher foi empregada para a demonstração da presença de leptospiras em cultivos de tecido renal. A microtécnica de soroaglutinação microscópica, com antígenos vivos, foi utilizada para a pesquisa de aglutininas, séricas, anti leptospiras. Os resultados obtidos confirmaram a atuação da estreptomicina para o controle da leptospiremia e da leptospirúria em uma única aplicação na concentração de 25 mg/kg de peso vivo. O ceftiofur sódico na concentração de 20 mg/ kg de peso vivo, uma ou duas aplicações com intervalo de 24 horas, não foi eficiente para sustar a evolução da infecção mas, nas concentrações de 25, 30 e 40 mg/kg de peso vivo, uma única aplicação, foi capaz de impedir a manifestação da doença. Uma única aplicação do ceftiofur sódico na dose de 25mg/kg de peso vivo foi capaz de eliminar a infecção renal em 48 dos 50 animais inoculados com diferentes concentrações de leptospiras.

RESUMO O trabalho teve como objetivo estimar, através do Método da Hipérbole, as exigências térmicas das fases de desenvolvimento e o número de gerações, mensais e anuais, de Ophyra aenescens, em Pelotas, RS. Para isso, estabeleceu-se uma colônia de O. aenescens, em condições de laboratório, para obtenção de ovos, larvas, pupas e adultos, os quais foram mantidos em temperaturas constantes (15oC, 20oC, 25oC e 30oC), com umidade relativa de 90% ± 5. As temperaturas base dos estágios de ovo, larva, pupa, pré-oviposição e ciclo total (ovo a ovo) foram de 8,3oC; 10,4oC; 9,1oC; 8,4oC e 9,4oC, respectivamente Enquanto que as constantes térmicas foram, respectivamente, de 20,0 GD; 90,3 GD; 159,8 GD; 109,8 GD e 376,5 GD. Constatou-se ainda, que a média de gerações por ano é de 9,14, podendo variar de 8,82 a 9,82. Mantendo-se o ciclo a 30oC, em condições de laboratório, é possível obter 19,9 gerações por ano, com viabilidade total de 75,97%.

RESUMO Em ranário próximo à São Paulo, relata-se grande perda de animais de engorda, manifestando apatia, inapetência, retardamento no crescimento, prolapso da cloaca, perda do tônus muscular e morte. A necropsia revelou fígado hipertrofiado, friável, de cor palha e manchado; coração hipertrofiado e isquêmico; rins hemorrágicos e hipertrofiados; intestinos hemorrágicos; reto e estômago edemaciados com paredes espessadas. Pela histopatologia, foi visto no fígado rarefação e degeneração celular protéica e hidrópica; no intestino, enterite, descamação epitelial e atrofia das vilosidades; no coração, dissociação das fibras musculares e, no baço, degeneração. O prolapso da cloaca está associado à enterite. Tais lesões sugerem um quadro degenerativo nutricional por intoxicação com deficiência protéica. No diagnóstico diferencial, a presença de aflatoxina foi negativa. No histórico do caso, o criador informou que a ração alterada foi ministrada aos animais por não ter outra disponível. Cuidados básicos no armazenamento da ração, bem como o conhecimento de alguns indicadores para uma ração deteriorada como mudança de cor, aspecto, odor, esfarelamento, grumos, compactação e bolor é fundamental, juntamente com um perfeito gerenciamento de estoque. Sugere-se a interrupção no fornecimento de alimento até que a ração seja substituída evitando-se as graves consequências decorrentes do uso do alimento deteriorado.

RESUMO Para verificar a preferência da colonização natural de Campylobacter nos segmentos do duodeno, jejuno, íleo, ceco, cólon e reto e também para classificar bioquimicamente as espécies isoladas, elaborou-se um estudo em 50 intestinos de suínos com enterite/diarréia, procedentes de matadouro e em idade de 4 a 6 meses. Após o raspado da mucosa intestinal de cada segmento, e vigorosa homogeneização em meio líquido de tioglicolato com pérolas de vidro, os isolamentos foram obtidos, por filtração e conseqüente semeadura sobre ágar tioglicolato com 20% de sangue bovino com incubação a 37ºC, e por semeadura direta da mesma mucosa sobre o mesmo ágar base, mas adicionado de meio seletivo de Butzler e com incubação a 43ºC. Ambas por 72 horas, em microaerofilia. Os resultados revelaram diferenças significativas, na colonização do Campylobacter entre os seis segmentos (P<0,001) e também na ocorrência no intestino delgado - 7 isolamentos - a intestino grosso - 4 isolamentos- (P<0,001), com maior freqüência no íleo com 12(57%) ocorrências (P<0,001). Não ocorreu, contudo, diferença significativa entre os segmentos do intestino grosso (P>0,05). Campylobacter coli foi a espécie mais freqüente com 11(52%) estirpes isoladas, distribuídas em 6(28,3%) no íleo, 3(14,4%) no ceco e 2(9,7%) no jejuno. Com exceção do Campylobacter mucosalis com 1(4,7%) isolamento no jejuno, as 3(14,4%) espécies classificadas Campylobacter jejuni/coli, as 2(9,7%) como Campylobacter lari e 1(4,7%) como Campylobacter jejuni, também demostraram preferências em colonizar o íleo, em relação aos 21 isolamentos das mesmas espécies em outros segmentos.

RESUMO Realizou-se estudo sobre os parasitóides associados às fezes bovinas. O objetivo das amostras foi verificar a freqüência dos parasitóides considerados importantes no controle de Diptera em Itumbiara e Cachoeira em Goiás. Vinte placas fecais bovinas foram coletadas aleatoriamente, a cada mês, com quinze dias de idade, colocadas em recipientes plásticos e levadas ao laboratório. Os pupários foram obtidos pelo método de flutuação em água. Observou-se que as fezes coletadas em Cachoeira Dourada apresentaram um maior número de indivíduos. As espécies de Spalangia podem ser consideradas os mais importantes inimigos naturais de Diptera coletados em fezes bovinas em Itumbiara e Cachoeira Dourada em Goiás.

RESUMO A co-cultura de células epiteliais de oviduto bovino (BOEC) supre as necessidades de desenvolvimento dos embriões bovinos do estádio de mórula até blastocisto expandido no processo de fecundação in vitro (FIV). Este estudo avaliou a sensibilidade das células epiteliais de oviduto bovino e murino ao vírus da rinotraqueíte infecciosa bovina. As culturas primárias de células epiteliais de oviduto bovino e murino foram infectadas com o vírus da rinotraqueíte infecciosa bovina (105.6 TCID 50/mL). O efeito citopático foi observado 48 horas após a infecção, e o vírus titulado em células MDBK. A avaliação preliminar mostrou que tanto as células de oviduto bovino quanto as de oviduto murino apresentaram efeito citopático característico do vírus da rinotraqueíte infecciosa bovina, com título, respectivamente de 106.5 TCID 50/mL e 104.8 TCID 50/ mL. Este estudo mostra que as células de oviduto murino são menos susceptíveis ao vírus da rinotraqueíte infecciosa bovina, as quais podem apresentar vantagens no co-cultivo de embriões bovinos fecundados in vitro
