Biofilm formation and antimicrobial resistance of Salmonella spp. isolates
Abstract
Abstract
The objective of the study was to evaluate the presence of Salmonella spp. in 89 samples of meat products marketed in southern Rio Grande do Sul and from isolates obtained was verified the ability of resistance to antimicrobials and biofilm formation on polystyrene surfaces. The presence of Salmonella spp. was found in 19.1% of the samples. Of the isolates obtained, 40% showed resistance to at least one of the tested antimicrobials and 33.3% expressed multiresistant. Only the antimicrobial amikacin (30 ?g) was effective in inhibiting all isolates tested. No isolate was able to form biofilms on polystyrene surfaces.
