25. ESQUEMA SIMPLIFICADO PARA IDENTIFICAÇÃO DE ESTAFILOCOCOS COAGULASE-POSITIVOS ISOLADOS DE MASTITE BOVINA
Os testes de produção de acetoína, determinação da atividade da enzima b-galactosidase e utilização anaeróbica do manitol em conjunto com a susceptibilidade à acriflavina foram avaliados para diferenciação de amostras de Staphylococcus coagulase-positivas (SCP) isoladas de mastite bovina. As amostras foram classificadas no gênero Staphylococcus p

26. COMPORTAMENTO DE ESTAFILOCOCOS COAGULASE NEGATIVOS PAUCIPRODUTORES DE ENTEROTOXINAS, EM ALIMENTOS EXPERIMENTALMENTE INOCULADOS
Linhagens de estafilococos coagulase negativos e pauciprodutores de enterotoxina de A a E, com capacidade de síntese variando de 1,4 a 16ng/mL oriundas de sítios anatômicos de cabras sadias, procedentes da Espanha, foram estudadas com o intuito de se avaliar a capacidade de desenvolvimento e produção de enterotoxina estafilocócica ("SE"), em alimentos

27. Características bioquímicas de cepas típicas e atípicas de Staphylococcus aureus isoladas de leite mastítico e de amostras ambientais de fazendas leiteiras brasileiras
Esse trabalho relata as características bioquímicas de 274 cepas de Staphylococcus aureus isoladas de leite mastítico, de mãos de ordenhadores e de ordenhadeiras mecânicas. Foram avaliadas as características morfológicas em agar Baird Parker (BPA) e os resultados para os testes de catalase, coagulase e termonuclease. API-Staph foi empregado como siste

28. Determinação da microbiota bacteriana de mosto e de dornas na fermentação alcoolica
Samples of concentrated yeast cell suspension diluted before the addition of sulfuric acid, of the same concentrated yeast cell suspension after addition and action of sulfuric acid, of must added to the same concentrated yeast cell suspension collected and of fermented must from the same fermentation tank, were collected between July and December of 1986, a

29. Identification of coagulase-positive Staphylococcus intermedius and Staphylococcus hyicus subsp. hyicus isolates from veterinary clinical specimens.
Coagulase-positive isolates of Staphylococcus intermedius from dogs and coagulase-positive isolates of Staphylococcus hyicus subsp. hyicus from a pig and cows were identified initially by a simplified scheme which can be readily performed in a routine diagnostic laboratory. Characters tested in the scheme included coagulase activity, colony pigment, and aero

30. Differentiation of staphylococci on the basis of nuclease properties.
The quantity, thermostability, and serological pattern of nucleases produced by different staphylococci were studied. Staphylococcal strains were isolated from nine different species of animals or from humans. Staphylococcus aureus, Staphylococcus intermedius, and Staphylococcus hyicus subsp. hyicus were vigorous producers of nuclease, whereas the coagulase-

31. Characteristic bacteriolytic activities of Staphylococcus hyicus.
Staphylococcus hyicus demonstrated characteristic bacteriolytic activities towards a Micrococcus luteus reference strain. This lytic activity was demonstrated on medium containing M. luteus cells as large zones of transparency around the culture streak. Smaller zones of transparency were observed with Staphylococcus intermedius, Staphylococcus chromogenes, a

32. Possible receptor for exfoliative toxins produced by Staphylococcus hyicus and Staphylococcus aureus.
Exfoliative toxin produced by Staphylococcus hyicus bound to the GM4-like glycolipid extracted from the skin of 1-day-old chickens but did not bind to glycolipid from adult chickens or suckling mice. Exfoliative toxin produced by Staphylococcus aureus bound to the GM4-like glycolipid extracted from the skin of suckling mice but not to glycolipid from 1-day-o

33. Biochemical properties of a novel metalloprotease from Staphylococcus hyicus subsp. hyicus involved in extracellular lipase processing.
Two extracellular proteases from Staphylococcus hyicus subsp. hyicus, ShpI and ShpII, have been characterized. ShpI is a neutral metalloprotease with broad substrate specificity; the gene has been cloned and sequenced. ShpII, characterized here, is mainly produced in the late logarithmic growth phase in contrast to ShpI, which is mainly produced in the late

34. Patterns of antibodies to staphylococcal DNases in dog sera.
Sera from clinically healthy dogs and from dogs with a history of skin disease were examined for the presence of antibodies to the DNases of Staphylococcus aureus, Staphylococcus hyicus subsp. hyicus, and Staphylococcus intermedius. The antibodies found most frequently and in the largest amounts were those to the DNase of S. intermedius.

35. Complete nucleotide sequence of the lipase gene from Staphylococcus hyicus cloned in Staphylococcus carnosus.
The lipase gene from Staphylococcus hyicus subsp. hyicus was cloned in Staphylococcus carnosus and Escherichia coli. In both host organisms the lipase gene is expressed and the enzyme is released to the medium. The cloned DNA insert is 2.5 kb in length and DNA sequencing has revealed the location of the gene, the ribosomal binding site and the presence of a

36. Cloning and Sequence Analysis of Genes Encoding Staphylococcus hyicus Exfoliative Toxin Types A, B, C, and D
Exfoliative toxins produced by certain strains of Staphylococcus hyicus mediate exudative epidermitis in pigs. In this study the genes coding for four different exfoliative toxin from S. hyicus (ExhA, ExhB, ExhC, and ExhD) were cloned and sequenced. The coding sequence of the four toxin genes ranged from 816 to 834 bp. The amino acid sequences of these four
