ABSTRACT=<p>Bovine mastitis is one of the most common diseases of dairy cattle. Even though different infectious microorganisms and mechanical injury can cause mastitis, bacteria are the most common cause of mastitis in dairy cows. Staphylococci, streptococci, and coliforms are the most frequently diagnosed etiological agents of mastitis in dairy cows. Staphylococci that cause mastitis are broadly divided into <italic>Staphylococcus aureus</italic> and non-aureus staphylococci (NAS). NAS is mainly comprised of coagulase-negative <italic>Staphylococcus</italic> species (CNS) and some coagulase-positive and coagulase-variable staphylococci. Current staphylococcal mastitis control measures are ineffective, and dependence on antimicrobial drugs is not sustainable because of the low cure rate with antimicrobial treatment and the development of resistance. Non-antimicrobial effective and sustainable control tools are critically needed. This review describes the current status of <italic>S. aureus</italic> and NAS mastitis in dairy cows and flags areas of knowledge gaps.</p>
