Ramírez C. Multidisciplinarias (Ciencias Sociales) capsule mastitis hemolysins clumping factor Staphylococcus aureus A total of 117 bacterial isolates obtained from bovine mastitis and positives to catalase, coagulase thermonuclease, mannitol and PCR tests were analyzed for virulence factor production: hemolysins (alpha and beta), clumping factor, and capsule. Additionally penicillin, oxacillin, streptomycin and oxytetracycline sensitivity were determined. Hemolysins and clumping factor production were two virulence factors expressed in the majority of the isolates (78%) and (73%) respectively, whereas that capsule formation was detected in 31% of the bovine isolates. A strong relationship between capsule absence and hemolysins production was observed since 72 of the 92 hemolytic strains were non capsulated. The absence of capsule was associated to Clfa production in 89% of the isolates positive to this factor. Sixty eight and sixty nine percent of the bacterial isolates were resistant to penicillin and oxacillin, respectively. Most of the isolates (116) expressed at least one virulence factor (hemolysins, capsule, clumping factor). The role of virulence factors and their relationship in the pathogenicity of S. aureus in bovine mastitis in México is under discussion. 2008 artículo científico 1665-5745 https://www.redalyc.org/articulo.oa?id=73011197007 en http://www.redalyc.org/revista.oa?id=730 e-Gnosis application/pdf Universidad de Guadalajara e-Gnosis (México) Vol.6 |
