title: Epidemiologic analysis of Leptospira spp. infection among sheep in Pernambuco state, Brazil

description: ABSTRACT: This study aimed to analyze epidemiological aspects and spatial characteristics of Lesptospira spp. infection among sheep in Pernambuco state, Brazil. A total of 426 samples were collected from unvaccinated animals aged 1 year or older, and submitted to Microscopic Agglutination Test (MAT). To study the risk factors, a standardized investigative survey of sheep farmers, with objective questions, was conducted to establish the general characteristics of the farm property production, reproductive management, and health plan. From 426 samples analyzed, 83 (19.5%; CI 15.9 - 23.6%) were positive; among them, the most prevalent serovar was Autumnalis (32.4%). Significant differences were observed between gender (OR = 0.38; CI 0.14 - 0.99), production system (OR = 2.03; CI 1.07 - 3.84), types of herd (OR = 2.28; CI 1.39 - 3.72), absence of rodents to the grain storage (OR = 0.55; CI 0.34 - 0.91), and restriction to surface waters (OR = 0.60; CI 0.37 - 0.99). Leptospira spp. infection is disseminated in sheep herds, and multiple factors can influence its occurrence. Health education programs and worker training in prevention and control of leptospirosis and other infectious diseases may be useful to reduce infection rates and economic losses caused by this disease.

title: Analysis of poultry transit, notification systems and legislation in the state of Sergipe, 2008-2012

description: ABSTRACT: The purpose of this study was to assess the transit of poultry, as well as the inspection on the outbreak of diseases, by addressing the issues concerning the system of the National Program on Poultry Sanity and its legal resolutions. The data on the animal transportation and the occurrence of the diseases were collected from the official services. A legislation-based assessment was also carried out for the period from 2008 to 2012 in the state of Sergipe, Brazil. Results showed an intense transit of poultry in just about all towns of the state in the period under study, especially in chicken farms where less number of poultry is bred: from 5,000 to 15,000. Besides, 64% of poultry transportation was found to be intermunicipal. The state of Sergipe has received poultry particularly from the states of Pernambuco (49.87%), Bahia (20.85%), Minas Gerais (5.94%), Paraíba (5.16%), and Goiás (5.05%). The number of transit indicates an increase in transit over the years. In addition, three of six municipalities which saw these diseases (Estância, São Cristóvão and Itaporanga d'Ajuda) are responsible for a great part of the poultry transit. Results also showed that the majority of activities of the State Program on Poultry Sanity would be carried out in the municipalities where a larger poultry marketing flow takes place, thereby seeking to record a greater number of notifications on the diseases and, then, carry out the surveillance activities. Therefore, regarding the poultry transit, it is recommended to do a mapping of the risk regions for poultry diseases, as well as studies about the epidemiological characterization of the municipalities of the state of Sergipe.

title: Comparison of complementary diagnostic methods of bovine tuberculosis on skin-test reactive cattle

description: ABSTRACT: The aim of this study was to compare different complementary diagnostic methods (macroscopic, histological, serological and molecular) of tuberculosis in naturally infected cattle. The study was conducted from samples taken from 40 reagents cattle in cervical comparative intradermal tuberculin test (ITT). The macroscopic post mortem inspection of carcasses was followed by the collection of nasal swabs, blood and tissue samples (liver, lung and mediastinal lymph node) for polymerase chain reaction (PCR) test, Enzyme-Linked Immunosorbent Assay (ELISA) and histopathologic test with hematoxylin-eosin (HE) and Ziehl-Neelsen (ZN), respectively. Of the 40 cattle slaughtered, 22 (55%) carcasses had macroscopic lesions suggestive of tuberculosis. The histopathology HE identified 13 (32.5%) carcasses with histological changes: 6 (15%) in the mediastinal lymph nodes, 5 (12.5%) in the liver and 3 (7.5%) in the lung. At ZN, the presence of acid-fast bacilli was not detected in any of the samples tested. The ELISA/IDEXX(r) identified one (2.5%) reagent animal, and the PCR test detected DNA of Mycobacterium bovis in one (2.5%) cow. It is concluded that among the diagnostic methods reviews none was able to detect all animals that were positive in tuberculin test, but the association of different methods can ensure diagnostic accuracy.

title: Mello and Campos (1974) method adapted for the recovery of cestodes in birds ( Gallus domesticus )

description: ABSTRACT: The specific diagnosis and evaluation of the intensity of avian helminth infections are essential for efficacy studies and the determination of drug doses targeted to their control. This study evaluated the Mello and Campos method, originally described for parasitological diagnosis in dogs, in the recovery of scolices from cestode parasites of poultry (Gallus domesticus ). A total of 52 naturally infected birds obtained from farms underwent parasitological necropsy using the Mello and Campos method. The method consisted of four steps: content, soaking, scraping and evaluation. The number of scolices recovered per bird ranged from 1 to 4,345, and the highest number of scolices was recovered from material derived from the soaking step. The cestodes species diagnosed were Amoebotaenia cuneata , Choanotaenia infundibulum , Hymenolepis sp., Raillietina tetragona , Raillietina echinobothrida and Raillietina cesticillus . The Mello and Campos method, originally used to test for helminths in dogs, was effective in avian cestode testing because it includes a soaking step, which enables a more efficient recovery of scolices.

title: Genetic stability in triticale estimated by pollen viability

description: ABSTRACT: The study aimed to infer about the genetic stability from the pollen viability in hexaploid triticale genotypes used in block crossings breeding program from Brazilian Company of Agriculture Research (Embrapa Wheat). The experiments were conducted in a randomized design. For each genotype five repetitions were assessed. Each replication consisted of one plant and each replication consisted of one plant. Two hundred pollen grains were analyzed by optical microscopy and by the squash technique with 1% acetic carmine dye per slide, totalizing 1,000 pollen grains per genotype. The variables analyzed were: binucleate and trinucleate pollen grains, with little starch, empty, with more than one pore and with different sizes. The data were submitted to analysis of variance and compared by Tukey test at 1%. There were significant differences between all variables. The percentage of binucleate and/or trinucleate grains ranged from 74 to 97%. We conclude that 66% of genotypes present pollen viability above 90% and they are indicated to remain of the breeding program of triticale, both in the selection of parenting as during the crossing and backcrossing. Therefore, the cytogenetic studies represent excellent support tool for breeder in selecting the most stable genotypes.

title: Control of globe fringerush ( Fimbristylis miliacea ) and selectivity to rice crop irrigated with bispyribac-sodium + metsulfuron-methyl associated with adjuvants

description: ABSTRACT: This study aimed to evaluate the control of globe fringerush (Fimbristylis miliacea ) and selectivity to rice crop irrigated with an in-tank mixture of bispyribac-sodium + metsulfuron-methyl associated with adjuvants. The experiment was conducted in the municipality of Douradina, Paraná state, Brazil (23º12'32.0" South, 53º17'39.9" West), in the agricultural year of 2012/2013. An experimental randomized complete block design with ten treatments and four replications was used. The treatments consisted of applying an in-tank mixture of the herbicides bispyribac-sodium + metsulfuron-methyl at two doses (32+1.3 and 40+3.3 g ai ha-1) associated with the adjuvants Iharaguen(tm) (375 mL.ha-1), Orobor N1(tm) (75 mL.ha-1), LI 700(tm) (150 mL.ha-1) and TA 35(tm) (50 mL.ha-1), as well as weeded and unweeded control. Although the effectiveness of globe fringerush (F. miliacea ) control with the in-tank mixture of the herbicides bispyribac-sodium + metsulfuron-methyl associated with Iharaguen(tm) and Orobor N1(tm) has been significantly higher than the effectiveness of these herbicides associated with LI 700(tm) and TA 35(tm), there were no significant differences among the treatments in terms of selectivity and grains yield of the rice cultivar Epagri 108.

title: Characterization of Ceratocystis fimbriata from passion fruits

description: ABSTRACT: Passion fruits (Passiflora edulis ) were found with symptoms of rot in the field, in the city of Tanhaçu, Bahia. After isolating the pathogen associated with this rot, in the present study we aimed to characterize the Ceratocystis isolate from passion fruit for better understanding this pathosystem. Molecular characterization was done based on the region ITS-5.8S rDNA. Pathogenic characterization was carried out for seedlings and fruits of passionflower. Passion fruit colonization was monitored by means of scanning electron microscopy techniques (SEM). DNA analysis of the Ceratocystis isolate from passionflower pointed out that this species belongs to Ceratocystis fimbriata . The inoculated passionflower seedlings showed injury at 30 days post-inoculation, but no inoculated plant showed wilt or died. Considering fruits, no differences were found for lesions caused by this fungus among cultivars, and lesions had average diameters of 1.0 and 2.2 cm at 7 and 11 days, respectively. The analysis using SEM indicated fungus spore germination and penetration in the fruit between 2 and 6 hours post-inoculation. At 12 and 24 hours post-inoculation, fruit colonization was noted both externally and internally, while fruit wall degradation started at 48 hours post-inoculation. At 90 hours post-inoculation, formation of new perithecia was observed inside and outside the fruit. This study complements the available information about the interaction of this fungus with passion fruit.

title: Diversity of frugivorous flies (Tephritidae e Lonchaeidae) in three municipalities in southern Bahia

description: ABSTRACT: The main goal of this paper was to know the species diversity of frugivorous flies (Tephritidae and Lonchaeidae) in Ilhéus, Uruçuca and Wenceslau Guimarães, municipalities in southern Bahia. In each sampled place five McPhail traps were used containing 5% corn hydrolyzed protein (Bio Anastrepha(c)), from July 2011 through December 2012. The captured adults were placed in plastic pots containing 70% alcohol, until identification, characterized according to diversity indexes of Shannon-Wiener, Margalef and equitability, and categorized according to the total number of captured flies: 2.24% species of genus Neosilba McAlpine (Lonchaeidae), and 97.76% species of genus Anastrepha Schiner, with 12 species reported, and Ceratitis capitata . The index fly/trap/day (FTD) oscillated from zero to 1.35 with the highest capture in March and April 2012, coinciding with the fructification period. The frugivorous flies captured were Anastrepha antunesi Lima, A. bahiensis Lima, A. consobrina (Loew), A. distincta Greene, A. fraterculus (Wied.), A. grandis (Macquart), A. leptozona Hendel, A. obliqua (Macquart), A. parallela (Wied.), A. serpentina (Wied.), A. sororcula Zucchi, A. zenildae Zucchi, C. capitata (Wied.), Neosilba glaberrima (Wied.) and Neosilba zadolicha McAlpine & Steyskal. Anastrepha fraterculus was the species with the highest index of frequency, dominance, abundance and constancy. It is the first register of A. consobrina in the state of Bahia.
