Resistência bacteriana e ação das bacteriocinas de Lactobacillus spp em Staphylococcus aureus isolados de mastite bovina

Staphylococcus aureus is the major pathogen causing intramammary infections in dairy cattle worldwide. Among the factors that contribute to its spread and infectious potential is the ability to overcome the mechanisms of antimicrobials activity. The present work investigated the antimicrobial resistance pattern and sensibility to bacteriocins produced by strains of Lactobacillus spp of 30 isolates of S. aureus from mastitis. From this, 29 are beta-lactamase producers. Eight isolates (26.6%) showed resistance to at least four antibiotics being considered multiresistent. All of them were mecA-po...
