local.description.resumoThis study aimed to evaluate the inhibitory effect of lactic acid bacteria (LAB) isolated from fermented transition milk against Staphylococcus aureus from cows with mastitis adhered to teat cup rubber and stainless steel surfaces of cows. Transition milk, collected from multiparous Holstein cows, was fermented for 33 days. LAB were isolated based on their different colony morphologies on MRS agar and identified using MALDI-TOF MS analysis. The antagonistic activity was determined by the double-layer diffusion assay and the inhibition of S. aureus biofilms by LAB supernatant. Among the LAB isolates evaluated, Lacticaseibacillus paracasei, Lacticaseibacillus casei, Lactobacillus rhamnosus, Enterococcus faecalis, and Enterococcus faecium were identified. Out of the fifteen LAB isolates, nine exhibited zones of inhibition ranging from 12.53 to 25.83 mm against two strains of S. aureus. Lower concentrations of both S. aureus strains adhered to stainless steel and rubber coupons were detected after 20 min of contact with the supernatants of three selected LAB when compared to the control. These findings suggest that the metabolites produced by the selected LAB could potentially be used as an alternative method to inhibit and control antimicrobial-resistant S. aureus strains, as well as reduce their biofilm formation.
