The objective of this work was to evaluate biofilm production, the susceptibility profile and the detection of resistance genes present in Salmonella isolates. spp isolates from fresh chicken carcasses sold in a Brazilian metropolis. Of a total of 61 samples of fresh poultry carcasses, 21 were positive for the presence of Salmonella spp. Regarding the antimicrobial susceptibility test, (13/21) the tested isolates were resistant to at least one antibiotic, corresponding to 61.9%, and 38% (21/08) were resistant to multiple drugs.
At least two resistance genes were identified in all isolates, especially genes related to β-lactamases and quinolone resistance. It was also observed that some Salmonella spp isolates presented identical genetic patterns. And all 21 isolates were capable of forming biofilm. The identification of Salmonella spp. biofilm. forming and transporting different β-lactamase genes and europe mobile number list quinolone resistance determinants demonstrates the ability of these bacteria to accumulate various mechanisms of virulence and resistance to antimicrobials. Therefore, the dissemination of different clonal groups of Salmonella spp. MDR in poultry meat carcasses expressed in this attest to the need for effective controls to contain this microorganism, which in addition to being a risk to public health, is also responsible for considerable economic losses. Keywords: Beta-lactams, Food poisoning, PCR, Public market. INTRODUCTION Salmonellosis is a foodborne illness caused by pathogenic strains of Salmonella spp.
Cases of salmonellosis in humans occur mainly through consumption of contaminated food or water. In most cases, foods of animal origin, especially poultry, are the main sources of Salmonella spp. infections. The symptoms of enteric infection are nausea, vomiting, non-bloody diarrhea, fever, cold, abdominal pain, myalgia and headaches, and in immunocompromised patients it can lead to bacteremia, endocarditis and death (GRIMONT and WEILL, 2007).
