Prevalence and characterization of Panton-Valentine leukocidin-positive Staphylococcus aureus in bovine milk in Jabalpur district of Madhya Pradesh, India
2. Department of Veterinary Pharmacology and Toxicology, College of Veterinary Science and Animal Husbandry, Jabalpur, Madhya Pradesh, India.
Background and Aim: The study aimed to investigate the Panton-Valentine leukocidin (PVL)-positive Staphylococcus aureus in bovine milk due to its public health significance.
Materials and Methods: A total of 400 milk samples of bovines taken from different dairy farms and outlets of Jabalpur were screened for the S. aureus and methicillin-resistant S. aureus (MRSA). The strains were tested for the PVL gene and antimicrobial sensitivity toward 10 different classes of antimicrobial agents. The PVL-positive S. aureus strains were further characterized by staphylococcal protein A or spa typing.
Results: The prevalence of PVL-positive S. aureus was 10.53%. All the isolates positive for the PVL were resistant to methicillin, while the methicillin-sensitive S. aureus isolates were negative for the PVL. Five different spa types were found.
Conclusion: The presence of PVL-positive MRSA in bovine milk close to consumer poses a potential public health risk to the community. Keywords: bovine milk, methicillin-resistant Staphylococcus aureus, Panton-Valentine leukocidin.
Keywords: bovine milk, methicillin-resistant Staphylococcus aureus, Panton-Valentine leukocidin.
