Dairy Staphylococcus aureus: Epidemiology, Drug Susceptibilities, Drug Modulation, and Preventive Measures

Staphylococcus aureus is an emerging pathogen from dairy animals’ mammary glands. Among various risk factors associated with this pathogen are unhygienic milking procedures, improper preventive techniques, and lack of germicidal teat dipping before and after milking. Methicillin-resistant S. aureus, coagulase positive S. aureus, vancomycin-resistant S. aureus, and biofilm-producing S. aureus are common strains of S. aureus being isolated from dairy milk these days. They have huge economic and public health concerns. Trials of antibiotic susceptibility proposed variable responses, while drug modulation and drug synergistic proved to be hope for its treatment. Some of the plant derivative, phages, and nanoparticles are non-antibiotic sources to treat S. aureus. Various attempts to treat S. aureus at the world level have been carried out but require more researches to be undertaken in order to prevent it. The chapter concludes that S. aureus from dairy needs equal attention as is given to S. aureus from the human origin, and researches are required to probe solutions
