Resumo: | Abstract Milk is extremelly valuable to the human diet and an excellent substrate for the growth of a wide range of microorganisms, including Staphylococcus aureus, frequently found in raw milk and one of the most prevalent microorganisms in cases of bovine mastitis in the world. The objective of this study was to evaluate the sensitivity of S. aureus strains isolated from raw milk to commercial antimicrobials. For this end, antibiotics based on research were selected from commercial establishments of veterinary drugs in the municipality of Zé Doca (Maranhão State, Brazil). The antibiotics were identified by association with penicillin, streptomycin, isoniazid and prednisolone (PCB), oxytetracycline base (TOR), a combination of penicillin and streptomycin (MPP), and tetracycline hydrochloride (TCA). Subsequently, Staphylococcus spp. counting was perfomed, with isolation and biochemical identification of strains of S. aureus, which were then submitted to antibiograms with identification of beta-lactamase producing strains. The results showed contamination in all samples by Staphylococcus spp., with counts ranging from 1.9 x 103 to 5.24 x 106 CFU/mL. Among the antibiotics tested, TOR showed the highest efficiency in elimination or reduction of all S. aureus strains. We found that 50% of S. aureus strains isolated produced the enzyme beta-lactamase. It is necessary to create measures to combat the emergence of new bacterial strains and to promote action by public authorities, supervising the commercialization of veterinary drugs. |

Objetivou-se avaliar a sensibilidade de cepas de S. aureus isoladas de leite cru à antimicrobianos comerciais. Para isso, selecionaram-se antibióticos com base em pesquisas junto a estabelecimentos comerciais de medicamentos veterinários no município de Zé Doca, Estado do Maranhão, Brasil. Esses antibióticos foram identificados por associação à base de penicilina, estreptomicina, isoniazida e prednisolona (BPC), oxitetraciclina base (TOR), associação à base de penicilina e estreptomicina (MPP) e cloridrato de tetraciclina (TCA). Posteriormente, realizou-se contagem de Staphylococcus spp., com isolamento e identificação bioquímica das cepas de S. aureus as quais, em seguida, foram submetidas à antibiogramas com identificação de ce,pas produtoras de beta-lactamase. Os resultados demonstraram contaminação em todas as amostras por Staphylococcus spp., com contagens de 1,9 x 103 a 5,24 x 106 UFC/mL. Dentre os antibióticos testados, o TOR apresentou maior eficiência na eliminação ou redução de todas as cepas de S. aureus. Verificou-se que 50% das cepas de S. aureus isoladas produziram enzima beta-lactamase. Torna-se necessário a criação de medidas de combate ao surgimento de novas cepas bacterianas e atuação das autoridades públicas, fiscalizando a comercialização de medicamentos veterinários.Universidade Estadual do Norte FluminenseInstituto Federal do MaranhãoUniversidade Federal do MaranhãoUniversidade Estadual PaulistaUniversidade Estadual PaulistaUniversidade Federal de GoiásUniversidade Estadual do Norte FluminenseInstituto Federal do MaranhãoUniversidade Federal do MaranhãoUniversidade Estadual Paulista (Unesp)Carvalho, Aparecida Selsiane SousaSerra, Josilene LimaRodrigues, Lucélia Da CunhaRodrigues Junior, Luciano De SouzaMouchrek, Adenilde NascimentoFerreira, Elka Machado2019-10-03T17:31:42Z2019-10-03T17:31:42Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article-application/pdfhttp://dx.doi.org/10.1590/1809-6891v19e-47159Ciência Animal Brasileira.
