Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) is a significant public health concern due to its zoonotic potential and multidrug resistance. This review provides a comprehensive overview of MRSA prevalence in livestock and companion animals in Pakistan, emphasizing its molecular epidemiology and resistance mechanisms. MRSA has been detected in bovine mastitis, raw milk, meat, and companion animals, with alarming prevalence rates across species and regions. Risk factors include poor hygiene, inappropriate antibiotic use, and close human-animal interactions, which contribute to its spread at the animal-human-environment interface. Advanced diagnostic tools like PCR and chromogenic media tests have facilitated rapid and accurate MRSA detection. The review also highlights alternative treatment strategies, including the use of medicinal plants, bacteriophage therapy, nanoparticles, and probiotics, as promising options to combat MRSA infections. Implementation of stringent hygiene measures, prudent antibiotic use, and further research into vaccines are critical to controlling MRSA in animals and safeguarding public health.
