Presence and Resistance Profile of spp. Isolated from Slaughtered Pigs.

The objective of this study was to isolate spp. and to characterize the resistance profile in nasal samples from pigs slaughtered for consumption. Intranasal swabs were collected from 100 pigs immediately after bleeding in a slaughterhouse located in the largest pork production region in Brazil, these samples were cultured and isolated to identify spp.

Presence of Staphylococcus spp. carriers of the mecA gene in the nasal cavity of piglets in the nursery phase.

The presence of Staphylococcus spp. resistant to methicillin in the nasal cavity of swine has been previously reported. Considering the possible occurrence of bacterial resistance and presence of resistance genes in intensive swine breeding and the known transmissibility and dispersion potential of such genes, this study aimed to investigate the prevalence of resistance to different antibiotics and the presence of the mecA resistance gene in Staphylococcus spp.

Pet dogs as reservoir of oxacillin and vancomycin-resistant Staphylococcus spp.

The aim of this study was to verify the bacterial resistance profile and detect the presence of mecA gene in Staphylococcus spp. isolated from the nasal microbiota of domiciled dogs. For this purpose 100 nasal swabs from 100 domiciled dogs were collected from the central area of the city of Umuarama (PR), along with a questionnaire answered by their owners.

Antimicrobial Resistance and Extended-Spectrum Beta-Lactamase Production in Enterobacteria Isolated from Free-Living Primates.

The aim of this study was to evaluate the profile of antimicrobial resistance in members of the family Enterobacteriaceae and to detect strains of extended-spectrum beta-lactamases (ESBL) in free-living . Oral and rectal swabs were collected from 15 primates to isolate and identify bacteria, conduct phenotypic tests to detect antimicrobial sensitivity and ESBL-producing strains, and calculate the multiple antimicrobial resistance index. The least effective antimicrobial was amoxicillin (72.

Detection of Enterotoxigenic Potential and Determination of Clonal Profile in Staphylococcus aureus and Coagulase-Negative Staphylococci Isolated from Bovine Subclinical Mastitis in Different Brazilian States.

Epidemiological studies have identified Staphylococcus aureus as the most common agent involved in food poisoning. However, current research highlights the importance of toxigenic coagulase-negative staphylococci (CoNS) isolated from food. The aim of this study was to characterize Staphylococcus spp.
