Summary: The resistance patterns of Staphylococcus aureus isolated from milk of dairy cows with mastitis, teat orifices and mouthpieces of the liners were studied. The samples from the milk and teat orifices were obtained before milking and samples from mouthpieces were obtained before and in the course of milking. The Kirby and Bauer standardized disc diffusion test was performed with previous confirmation of isolates by molecular method. The resistance to penicillin was predominant to the isolates from milk, teat orifices and mouthpieces (48.3%, 36.8% and 25.9%, respectively). The resistance to oxacillin was found in all sources studied, with characteristics of multidrug resistance. The bovine mastitis treatment is recommended after sensitivity tests to the different antimicrobials of microorganisms responsible by aetiology. The identification of strains oxacillin-resistant explains the care with the possibility of transmission of S. aureus by milk.

As amostras de leite e dos óstios foram obtidas antes da ordenha dos animais e as das teteiras antes e durante a ordenha. Os testes de sensibilidade in vitro foram realizados de acordo com a técnica de Kirby e Bauer, utilizando-se 12 princípios ativos, com confirmação prévia de todas as amostras de S. aureus por técnicas moleculares. O perfil de resistência mais comum de S. aureus isolados no leite, óstios e insufladores foi à penicilina (48,3%, 36,8% e 25,9%, respectivamente). Além disso, em todas as fontes estudadas encontrou-se S. aureus com resistência à oxacilina, com características de multiresistência a outros antimicrobianos. O tratamento da mastite bovina deve ser realizado somente após o conhecimento da sensibilidade dos microrganismos responsáveis pela etiologia da doença aos diversos antimicrobianos. O isolamento de estirpes resistentes à oxacilina ilustra os riscos de transmissão destes patógenos pelo leite.Instituto Adolfo Lutz2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://periodicos.saude.sp.gov.br/RIAL/article/view/3277810.53393/rial.2008.67.32778Instituto Adolfo Lutz Journal - RIAL; Vol. 67 No. 2 (2008); 118-125Revista del Instituto Adolfo Lutz - RIAL; Vol. 67 Núm. 2 (2008); 118-125Revista do Instituto Adolfo Lutz; v. 67 n. 2 (2008); 118-1251983-38140073-9855reponame:Revista do Instituto Adolfo Lutz (Online)instname:Instituto Adolfo Lutzinstacron:IALporhttps://periodicos.saude.sp.gov.br/RIAL/article/view/32778/31609Copyright (c) 2008 Luiz Francisco Zafalon, Juliana Rodrigues Pozzi Arcaro, Antônio Nader Filho, Luciano Menezes Ferreira, Lívia Castelani, Fabiane Benvenuttoinfo:eu-repo/semantics/openAccessZafalon, Luiz FranciscoArcaro, Juliana Rodrigues PozziNader Filho, AntônioFerreira, Luciano MenezesCastelani, LíviaBenvenutto, Fabiane2024-01-22T18:16:19Zoai:ojs.periodicos.saude.sp.gov.br:article/32778Revistahttps://periodicos.saude.sp.gov.br/RIAL/indexPUBhttps://periodicos.saude.sp.gov.br/RIAL/oairial@saude.sp.gov.brhttps://doi.org/10.53393/rial1983-38140073-9855opendoar:2024-01-22T18:16:19Revista do Instituto Adolfo Lutz (Online) - Instituto Adolfo Lutzfalse
