Resumo: Considering the high prevalence of subclinical mastitis and its impacts on milk production, thematic studies are needed and can provide strategic data for its control. This study aimed at investigating the most frequent microorganisms associated with subclinical mastitis in dairy cows in the northwest State of Paraná, Brazil and its sensitivity to antibiotics. A total of 478 foremilk samples were tested. Streptococci were the most frequently genus observed (63%), followed by staphylococci (31%). Streptococcus mutans, S. sanguis, and S. uberis were the most frequently identified species. For Streptococcus spp., the antimicrobial resistance was higher for Ceftiofur, whereas for Staphylococcus spp. it was also possible to verify a high occurrence of resistance for Gentamicin + Amoxicillin. Our results strengthen the knowledge of the microbiological agent and antibiotic-resistance patterns of pathogens at regional level, targeting future strategies to reduce the environmental spread of pathogenic strains resistant to antibiotics.

Este estudo teve como objetivo investigar os microrganismos associados à mastite subclínica em vacas leiteiras no noroeste do estado do Paraná e sua sensibilidade a antibióticos. Foram testadas 478 amostras de leite. Os estreptococos foram os micro-organismos mais frequentemente observados (63%), seguidos pelos estafilococos (31%). Streptococcus mutans, S. sanguis e S. uberis foram as espécies identificadas em maior frequência. Para Streptococcus spp., a resistência antimicrobiana foi maior para Ceftiofur, enquanto para Staphylococcus spp. foi possível verificar alta ocorrência de resistência para Gentamicina + Amoxicilina. Esses resultados ampliam os conhecimentos sobre os agentes microbiológico envolvidos em mastites subclínicas e seus padrões de resistência a antibióticos em nível regional, possibilitando estratégias para reduzir a propagação ambiental de cepas patogênicas resistentes a antibióticos.UEL2022-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionObservational - cross-sectional studyAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4580610.5433/1679-0359.2022v43n5p2385Semina: Ciências Agrárias; Vol. 43 No. 5 (2022); 2385-2394Semina: Ciências Agrárias; v. 43 n. 5 (2022); 2385-23941679-03591676-546Xreponame:Semina.
