| ABSTRACT. Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability of roosts are important aspects of their ecology. Karst areas have great potential for the availability of day roosts, since they form caves, which serve as bat shelters. Here we characterize the caves used by bats in a preserved karst area of Southeastern Brazil. Using logistic regression analysis we identified the cave characteristics that influence bat occupation. Sixty-six caves were characterized based on measurements of internal height and width, height and width of the entrance(s) of the cave, number of entrances, maximum horizontal development of cave, and internal temperature and humidity. In nineteen months we found 14 species in 32... |

| ABSTRACT: This study was accomplished with the aim to evaluate and to characterize the risks for the presence of Megninia spp. in poultry farms from Minas Gerais, using for that Correspondence Analysis (CA). A secondary database was used and adapted for this study, with information from 402 chicken houses of 42 laying hens commercial properties. Variables used to compose the correspondence model were selected through tests of Qui-square being considered the significant result of P≤0,05. A risk index was built to the presence of Megninia spp. starting from variables considered as risk factors for the presence of those ectoparasites. The CA graph produced for the epidemiological characterization of the presence of Megninia spp. presented an accumulated... |

| ABSTRACT Veterinary drug residues in bulk tank milk are important to all sectors of the dairy chain because they are one of the major factors which determine the safety of the final product. This study attempted to identify milk quality parameters that are associated with the occurrence of veterinary drug residues using multivariate principal component analysis (PCA). A total of 132 raw milk samples were collected from 45 dairy farms in the state of Minas Gerais - Brazil and analyzed for 42 analytes, including pyrethroids, macrocyclic lactones and antibacterials, using liquid chromatography coupled with mass spectrometry in tandem mode and gas chromatography with electron capture detection. Out of the 132 milk samples, 40 samples tested positive for at... |

| O presente estudo teve como objetivo determinar a prevalência e a distribuição espacial da leishmaniose visceral em cães (LVC) do município de Juatuba, Minas Gerais, Brasil, no ano de 2010. Foi realizado um estudo observacional transversal por meio de coleta de amostras sanguíneas de 957 cães, definidos aleatoriamente em todos os bairros do município. No diagnóstico sorológico, foram utilizados os testes de Imunofluorescência Indireta (IFI) e Teste de Adsorção Enzimática (ELISA), preconizados pelo Ministério da Saúde (MS). Foram marcadas as coordenadas geográficas dos imóveis participantes da pesquisa para verificar a distribuição espacial dos casos caninos. A prevalência da LVC foi estimada em 10,6%, com variação de 3 a 50%, distribuída em 70,6% dos... |

| ABSTRACT: This study aimed to determine the virulence factors, phylogenetic groups, and the relationships between pathovars and phylogenetic groups of E. coli strains isolated from feces of buffalo calves. A total of 217 E. coli strains were obtained from feces after culture and were screened by PCR for detection of virulence factors EAST-1, enterohemolysin, Saa, CNF2, F41, F5, STa, intimin, Stx1 and Stx2. One hundred and thirty-four isolates were positive for one or more virulence factors: eighty-four from diarrheic animals, and fifty from non-diarrheic calves. The pathovars of E. coli identified in diarrheic feces were ETEC (F5+) (2/84), NTEC (16/84), STEC (20/84), EPEC (3/84), EHEC (3/84), and EAEC (EAST-1+) (33/84). Pathovars identified in... |
