Antibiotic Sensitivity Pattern of Staphylococcus spp. Associated with Mastitis in Cow's Milk

Abstract

Bovine mastitis is an inflammation of the mammary gland and udder tissue caused by physical trauma or bacterial infection. This condition manifests through physical changes in the udder or biochemical changes in milk, posing a concern for public health due to potential economic losses from reduced milk yield and quality. Treating bovine mastitis has become increasingly challenging due to antimicrobial resistance (AMR) developed by pathogens like Staphylococcus aureus, a major cause of mastitis known to acquire resistance to methicillin and other critical antibiotics. There is also a risk of transferring these resistant bacteria or their antibiotic resistance genes (ARGs) to humans and the environment. This has become a significant concern making it crucial to monitor the presence of resistance associated with mastitis in the dairy sector. This study specifically focuses on profiling antibiotic resistance patterns of S. aureus isolated from mastitis-infected milk samples collected from a farm in Melaka.
