title: OVIPOSITION PREFERENCE AND ITS RELATION TO THE PERFORMANCE OF DIAPHANIA HYALINATA (L., 1758) (LEPIDOPTERA: CRAMBIDAE) IN CUCURBITS.

description: ABSTRACT Diaphania hyalinata L. (Lepidoptera, Pyralidae) stands out as a major pest of the Cucurbitaceae family. This insect is oligophagous with a polyphagous habit, which arouses wide interest in studies of their behavioral ecology for reasons of pest management in crops of high economic importance such as muskmelon (Cucumis melo L.). Given this situation, basic studies aimed at an understanding of ecological aspects of this pest are needed to improve pest management systems, especially in the aspect of population monitoring. Given this, the present study was aimed to determine whether the choice of the host exerted by females of D. hyalinata corresponds to the best performance of the offspring and how the hosts influence their population dynamics. Oviposition-choice tests were performed on melon, watermelon, cucumber, loofah, balsam apple and cucumber, to establish a ranking of preference. For the performance of larvae and reproduction the melon was chosen (among the most preferred hosts) along with loofah and cucumber (among the least preferred hosts). The results support the hypothesis that the choice of host is related to the performance of the offspring and D. hyalinata has demonstrated plasticity in dealing with different hosts which may be indicative of ability to adapt to fluctuating food resources in terms of quality and availability. However, generally this plasticity is expensive, especially in reproductive terms.

title: IN VITRO EVALUATION OF THE SUSCEPTIBILITY OF CORYNEBACTERIUM PSEUDOTUBERCULOSIS TO DIFFERENT KINDS OF ANTISEPTICS AND DISINFECTANTS

description: ABSTRACT The aim of this study was to evaluate the in vitro effect of antiseptics and disinfectants against Corynebacterium pseudotuberculosis, and to define the growth curve of this microrganism inoculated in brain heart infusion broth plus 0.1% of Tween 80 (BHI + T), for 48 hours incubation. For the susceptibility test, evaluations were made using 10% iodine, 2.5% sodium hypochlorite, 5% potassium permanganate, Aseptol® liquid soap, and absolute ethyl alcohol (99.8%), by way of the disc-diffusion method. A sterile swab was immersed in a bacterial suspension and plated in Mueller-Hinton agar. Sterile discs were immersed in each solution to be tested and distributed on the agar surface. The results were obtained according to the inhibition circle diameter formed around the disc. For the growth curve determination, colonies were inoculated in a bottle containing BHI + T. Every 4 hours, 2 mL was withdrawn to evaluate the cell mass in a spectrophotometer, and 1 mL was taken to perform serial dilutions, blood agar base plating and counting of viable cells. It was observed that in order to reach the maximum concentration of C. pseudotuberculosis, close to 1,200 x 105 viable cells/mL, the inoculum must be maintained at appropriate incubation for a period of 28-40 hours. The sensibility test indicated

title: SEROLOGIC INQUIRY OF TOXOPLASMA GONDII IN SHEEP IN NORTHERN BRAZIL

description: ABSTRACT Toxoplasmosis is a serious zoonosis and widespread parasitic disease. A serologic inquiry in Santo Antonio do Tauá and Santa Izabel do Pará counties in the Castanhal Microregion, state of Pará, Northern Brazil, demonstratedahighfrequency,(44.29%) ofanti-Toxoplasmagondii antibodies detected by indirect hemaglutination test, with a distribution at titers 1:64, 1:128, 1:256, 1:512, 1:1024 and 1:2048 of, respectively, 50 (32.26%), 42 (27.10%), 29 (18.70%), 11 (7.10%), 12 (7.74%) and 11(7.10%). A statistically significant difference was observed between the 0 up to 2 and &gt; 2 age groups in both sexes (?2 = 13.42, p = 0.0002) with a greater frequency in the &gt; 2 years age group, (58.71%), and between the sexes (?2 = 23.51, p = 0.0001) with a greater frequency in females, (72.26%). Although the two counties presented similar frequencies (49.33% and 40.50% for Santa Izabel do Pará and Santo Antonio do Tauá, respectively) no association was observed between them. Sanitary surveillance measures are recommended to prevent health risks to humans and animals.

title: DAMAGES CAUSED BY MASTITIS IN SANTA INÊS BRAZILIAN SHEEP BREED

description: ABSTRACT In meat sheep herds in Brazil, mastitis has provoked many damages, causing mortality and decreasing the numbers of lambs born and weaned, posing heavy economic impacts for the production system. The objective of this study was to quantify the damages caused by mastitis in a Santa Inês breed herd, reared in a semi-intensive production system, in São Paulo State, Brazil. Clinical exams were conducted and the California mastitis test was carried out, and milk samples were taken from the ewes for microbiological assay. The lambs were weighed at birth and on the days when the milk samples were taken. Forty-one ewes gave birth to 55 lambs (birth rate of 1.34) during the parturition season from 23 October 2008 to 4 January 2009. Twenty (36%) of them died, 14 (70%) in the first 2 weeks following birth, and 6 (30%) before weaning, which occurs at about 70 days. A total of 70% (14) of the deaths were imputed to the occurrence of mastitis in the respective ewe, and 30% (6) to other causes, mainly pneumonia. Mastitis decreased the average daily gain of the lambs from birth to weaning (P &lt; 0.10). Most of the positive microbiological samples (85.8%) where positive for Staphylococcus spp.

title: MICROBIOLOGICAL PROFILE OF FISH AND POND WATER IN FEE-FISHING LOCATED IN THE NORTHEAST REGION OF SÃO PAULO STATE, BRAZIL

description: ABSTRACT The objective of this study was to determine the number of total and thermotolerant coliforms, coagulase-positive Staphylococcus, and the presence of bacteria of the genus Salmonella in the muscle, surface tissue, and gastrointestinal tract of fish, and in the pond water of fee-fishing establishments located in the Córrego Rico microwatershed in the state of São Paulo, Brazil. Coagulase-positive Staphylococcus was not detected in any sample of pond water or fish. The most probable number (MPN) of total coliforms in fish ranged from 2.0 x 10 to &gt; 1.1 x 104 NMP.100 mL-1, while in pond water it ranged from 4.2 x 104 to &gt; 2.4 x 105 NMP.100 mL-1. The count of thermotolerant coliforms in fish ranged from &lt; 3 to 5.1 x 103 NMP.g-1, while in pond water it ranged from 3.8 x 102 to 2.0 x 104 NMP.100 mL-1. There was no statistical difference (P &gt; 0.05) among the studied populations of microorganisms in pond water, surface tissue and gastrointestinal tract, which reflects a relationship between the presence of microorganisms in the water and in the two tissues analyzed. Salmonella sp. was isolated in one sample of muscle and in two samples of gastrointestinal tract. The fish can be a vehicle for cross contamination, having the gastrointestinal tract and the surface tissue as a source of microorganisms for its muscles. Therefore, monitoring the water quality is important to ensure the production of fish with good quality.

title: RESISTANCE TO ANTIMICROBIALS AND ANALYSIS OF STAPHYLOCOCCUS AUREUS GENETIC DIVERSITY USING RAPD-PCR

description: ABSTRACT The aim of this study was to analyze in vitro antimicrobial susceptibility of Staphylococcus aureus strains isolated from teats of cow udders and milking workers’ hands as well as to verify polymorphism among them by using RAPD-PCR technique. Tests were conducted by disk diffusion technique and after the collection of the genetic material PCR and RAPD techniques were performed with the use of 40 different initiators. The analysis of polymorphism was conducted by using the NTSYS program of numerical taxonomy. The susceptibility of antimicrobials in the strains collected from teats of cow udders was 4% to penicillin, 88% to tetracycline, 92% to gentamicine, 96% to vancomycin and 100% to chloranfenicol. As for the strains collected from milking workers’ hands, susceptibility results were 0% to penicillin, 70% to tetracycline and 90% to vancomycin and 100% to gentamicine and chloranfenicol antimicrobials. E-test showed minimum inhibitory concentration (MIC) greater than 256 ?g/mL to strains resistant to the antimicrobial vancomycin. The studies made it possible to detect S. aureus resistance upon the use of the tested antimicrobials and to determine the genetic diversity found among strains of staphylococcus due to the presence of many polymorphic bands found in all initiators.

title: BEHAVIOUR OF YELLOW PASSION FRUIT, AFRUVEC VARIETY, IN RELATION TO A POPULATION OF FUSARIUM SOLANI, CAUSAL AGENT OF COLLAR ROT

description: ABSTRACT The objective of the present work was to verify the behavior of yellow passion fruit, Afruvec variety, in relation to a population of Fusarium solani, obtained from this crop. The experimental delineation was random blocks, containing 10 treatments [9 isolates and 1 control treatment], with 4 repetitions, each plot being represented by a vase containing a plant. A disk of culture medium colonized by each isolate of the fungus was inoculated in the wounded collar region of the plants of the Afruvec variety two months after sowing. The appraised parameters were: the pathogenicity, the incidence (number of dead plants) and the severity of the disease (length of the lesion in the collar region), until 60 days after inoculation. The Afruvec variety was susceptible to the fungus and also presented variability as to the severity of the disease and incidence in relation to the different isolates. The population of the fungus showed variability in regard to aggressiveness. In light of the evidence of genetic diversity in the F. solani population, it is also suggested, in the tests of selection of materials to the pathogen, that these materials should be evaluated in different places with a history of the disease or inoculation with a pool of isolates of the fungus, in order to know the wide resistance of the genotype to the pathogen.

title: EVALUATION OF THE HEALING ACTIVITY OF PEQUI (CARYOCAR CORIACEUMWITTM) OIL IN CUTANEOUS WOUNDS INDUCED EXPERIMENTALLY IN RATS

description: ABSTRACT The main objective of this study was to demonstrate the effects of topical treatment with ointment containing pequi oil (Caryocar coriaceum Wittm), using 40 male 60-day-old mice (Rattus norvegicus albinus) from the Wistar line. These were divided into two groups: I) composed by 20 mice with cutaneous wounds treated by topical application of the ointment based on 10% pequi oil; II) the same number of mice, receiving the topical application of ointment without pequi oil. After antisepsis and local anesthesia, round 1-cm-diameter wounds were made on the lower back region. The wounds were evaluated in regard to clinical, morphometric and histological aspects on the 3rd, 7th, 14th and 21st postoperative days. The group treated with the pequi ointment presented acceleration in the healing process. The animals’ wounds of this group showed a meaningful reduction from the 14th postoperative day, when histological characteristics from the ending of the healing process were noted, such as a large amount of fibroblasts, collagen fibers and a complete process of reepithelialization, while the wounds of the control group needed more time for the healing process.

title: SHIGATOXIN-PRODUCING ESCHERICHIA COLI DETECTED IN DAIRY CATTLE FECES

description: ABSTRACT The purpose of this study was to determine the prevalence of Shigatoxigenic Escherichia coli (STEC) and serogroups O157, O111 and O113 in dairy cattle from Jaboticabal, state of São Paulo, Brazil. Feces samples were collected from 10 herds and assessed for the presence of the virulence genes stx1, stx2 and eae by polymerase chain reaction (PCR). All samples positive for stx and eae were submitted to a second PCR reaction targeting the sequences rfb O157, rfb O111 and rfb O113. A high prevalence of stx (72.16%) was detected in the fecal samples, the most frequent being stx1 associated to stx2. The prevalence of sequences rfb O157, rfb O111 and rfb O113 was 14.77%, 0.2% and 30.83%, respectively. STEC and serogroup O113 was identified in all herds (100%), and serogroups O157 and O111 were observed in 60% and 10% of the herds. In conclusion, the high STEC prevalence detected in dairy herds evidences that bovine feces might play an important role as a contamination source in the region of Jaboticabal.

title: FREQUENCY OF LEPTOSPIROSIS IN OVINE SLAUGHTERED IN PATOS, PARAÍBA, BRAZIL

description: ABSTRACT Placenta, ampulla of the deferent duct, and seminal vesicle samples were collected from 80 sheep slaughtered in the public slaughterhouse of Patos, Paraíba state, Northeastern region of Brazil, for isolation of Leptospira spp., and blood samples were taken from the same animals to check for the presence of anti-Leptospira spp. antibodies. Ellinghausen-McCullough-Johnson-Harris (EMJH) medium modified with the addition of 10% rabbit serum was used for the leptospira isolation, while the microscopic agglutination test (MAT) was used to check for the presence of antibodies. The cultures were observed weekly by dark field microscopy for 16 weeks. Six animals (7.5%) were seropositive by MAT, the serovar Autumnalis being the most frequent, with 5 reactant sera, followed by the serovar Icterohaemorragiae, with 1 reactant serum. A microorganism morphologically similar to Leptospira spp. was isolated from 1 ampulla of the deferent duct sample and 1 placenta sample.

title: BIOSAFETY: A REVIEW

description: ABSTRACT Biosafety is a set of actions directed to the prevention, minimization or elimination of risks that could jeopardize the human’s and animal’s health and of the environment. The first debates about biosafety were held in the early 1970’s due to the outbreak of transmissible diseases and to the concern to the safety in laboratory arenas. In Brazil, the regulations to activities related to these areas began in 1995 with the formation of the National Technical Biosafety whose functions are the inspection of the manipulated Genetically Modified Organisms (GMO) and of the laboratory arena safety. This review describes the biosafety concepts and their applicability known in order to improve the human safety as well as the environment in related issues to the research activities, production, teaching, technological development and given service.

title: CHEMICAL MANAGEMENT OF THE SOYBEAN ASIAN RUST BASED ON DIFFERENT MONITORING METHODS

description: ABSTRACT The objective of this study was to determine the ideal time for the application of the fungicides of preventive action (Opera + Assist)* and (PrioriXtra + Nimbus)*, based on the initial detection of early spores associated with environmental conditions, climate monitoring and conventional monitoring (after the detection of the first symptoms), verifying their effectiveness in the control of Asian soybean rust. The study was conducted at the Londrina State University Experimental Station, where spore collectors were installed in the area for early detection of spores and the climate conditions were monitored in a climate station. The applications were made at 1, 7, 14 and 21 days after first detection of spores, according to the climate monitoring and conventional monitoring. Evaluations were made of the infected leaf area, defoliation and soybean yield. There was a lower percentage of leaf infection when the products were applied early in the detection of spores (1, 7 and 14 days after detection), and according to the climate monitoring. Moreover, despite that the product (Nimbus + PrioriXtra)* presented lower percentages of infected leaf and defoliation when applied at the different times, it was observed that in the final yield of the crop there was no difference between the products tested.

title: EVALUATION OF THE POTENTIAL OF THE MEDICINAL PLANT ADIANTUM CAPILLUSVENERIS (L.) FOR THE CONTROL OF PHYTOPATHOGENS

description: ABSTRACT The use of secondary compounds of medicinal plants, with antimicrobial properties, can be an alternative for the control of phytopathogens. The aim of the present study was to evaluate the antimicrobial activity of derivatives obtained from the medicinal plant Adiantum capillus-veneris (maidenhair fern) against phytopathogenic fungi and bacteria. The derivatives, obtained from the powder of shadow-dried maidenhair fern leaves, were prepared by infusion, maceration and decoction, autoclaved and non-autoclaved, in the concentration of 0.1%, 0.25%, 0.5%, 1%, 1.25%, 2.5%, 5%, 10%, and 20%. The germination of Phakopsora euvitis and Pseudocercospora vitis spores, the mycelial growth of Colletotrichum musae and Sclerotium rolfsii, and the multiplication of Erwinia sp. and Bacillus subtilis bacteria were evaluated. The extract obtained by non-autoclaved maceration presented the best effect against P. euvitis, with reduction of 75% on uredospores germination in the concentration of 20%. Against P. vitis, the derivative obtained by non-autoclaved maceration was more effective, presenting 99% of reduction on conidia germination in the concentration of 20%. The smallest mycelial growth of C. musae and S. rolfsii was obtained by autoclaved maceration with 39% and 83% reduction, respectively. For Erwinia sp., the greatest inhibitory effect was obtained with the 25% autoclaved maceration that inhibited the bacterial growth at 99%. For B. subtilis, there was no significant inhibition. These results indicate the potential of maidenhair fern derivatives for the control of phytopathogens.

title: IN-VITRO EVALUATION OF EXTRACT OF MEDICINAL PLANTS FROM CERRADO AGAINST THE STAPHYLOCOCCUS AUREUS ISOLATED FROM DIFFERENT ORIGINS ON DAIRY FARMS

description: ABSTRACT The objective of this study is to evaluate the potencial microbial activity in-vitro from the extract of some endemic plants from Cerrado such as Baccharis dracunculifolia. Cochlospermum regium. Croton antisyphiliticus. Eugenia dysenterica and Lippia sidoides, against the agent Staphylococcus aureus isolated from bovine mastitic milk, osteo from cow’s teat, milker equipament, nasal cavitites and milker’s gullet. The extracts were prepared from aerial parts as well as the reticular systems of plants using the solvents methanol, hexane and chloroform at a concentration of 10%. To evaluate the antimicrobial activity, the technique of microdilution in broth was used for determining the Minimal Inibitory Concentration (MIC) followed by the determination of Minimal Bactericidal Concentration (MBC). The extracts from Baccharis dracunculifolia and Croton antisyphiliticus, followed by extracts from Lippia sidoides, reported respectively, presented better inhibitory activity against the multiplication of the bacteria Staphylococcus aureus. Furthermore, the results demonstrate that the isolated strains from the milk and nasal cavities of the milker showed strong resistance against gentamicin, active agent commonly applied to combat mastitis bovine. However, there was sensitivity against extracts from the reported plants, reinforcing the importance of the medicinal plants as a therapeutic resource and its aplicability.

title: PREVALENCE OF ANTIBODIES AGAINST THE AGENTS OF MAEDI-VISNA AND CHLAMYDOPHILOSIS IN SHEEP FROM UBERLÂNDIA COUNTY, MG, BRAZIL

description: ABSTRACT The aim of this study was to carry out the first investigation into the serological prevalence of maedi-visna virus and Chlamydophila spp. on 12 sheep breeding farms in Uberlândia County, MG, Brazil. A total of 334 blood serum samples were used and an epidemiological survey was completed by each farm. The tests to detect maedi-visna and Chlamydophila spp. antibodies were an agar gel immunodiffusion (AGID) and a complement fixation test (CFT), respectively. None of the sheep were reactive to maedi-visna. The detection of antibodies against Chlamydophila spp. was 3.3%, with titers varying from 32 to 64. There was no statistically significant difference (p &gt; 0.05) in regard to the risk factors analyzed. The importance of epidemiological surveillance systems to aid in the control of these infections is emphasized, in order to avoid the introduction of maedi-visna virus and a wider spread of Chlamydophila spp. in this county.

title: RESISTANCE PROFILE OF ESCHERICHIA COLI ISOLATED FROM THE ENVIRONMENT.

description: ABSTRACT The aim of this study was to determine the antimicrobial resistance of 43 Escherichia coli strains isolated from the Santo Antonio weir (Fortaleza, CE, Brazil) from January to April 2007. Susceptibility tests performed with 8 antimicrobials indicated that 67.5% of the strains were susceptible to all of them. Resistance to tetracycline (25.6%), sulfazotrim (18.6%), nalidixic acid (9.3%), and ciprofloxacin (4.7%) was observed. The strains did not show resistance to betalactamics. Nine strains (21%) were multiresistant, the resistance being chromosome (78%) and plasmid (56%) mediated. The presence of resistant bacteria may be related to antimicrobials in the sewage discharged into the weir, and the inappropriate use of this body of water may pose human health risks.
