Antimicrobial resistance (AMR) is one of the leading threats in healthcare management system. Staphylococcus aureus is a commensal bacteria commonly seen on skin and nasal passage that can turn as an opportunistic pathogen. The present study was carried out to evaluate the nasal carriage of S. aureus and methicillin-resistant S. aureus (MRSA) among apparently healthy companion animals and livestock. A total of 160 nasal swabs were collected from dogs (30), cats (30), cattle (40), goats (30), and pigs (30). All the samples were initially screened for prevalence of S. aureus, which was confirmed by PCR using species specific primer (nuc gene). All the S. aureus isolates were screened for occurrence of MRSA, both phenotypically (by double disc diffusion using cefoxitin and oxacillin discs) and genotypically (by PCR targeting mecA gene). There was significant difference in nasal carriage of S. aureus among animal population (Chi-square value – 33.206, p-value < 0.001), which was found as 76.67 per cent, 23.33 per cent, 53.33 per cent, 62.5 per cent, and 86.67 per cent among dogs, cats, cattle, goats, and pigs respectively. None of the nasal swabs from animals were positive for MRSA. The present study signifies the occurrence of nasal carriage of S. aureus and absence of MRSA among domestic animal population of Wayanad district.
