The most related microorganism in cases of bovine mastitis are Staphylococcus spp. Some strains of these microorganisms have shown virulence factors like antibiotic resistance genes, such as the resistance to methicillin, which represents a public health problem. This literature review aims to compile data related to bovine mastitis caused by Staphylococcus spp. Methicillin-resistant (MRS). Despite this antimicrobial not be commonly used in the treatment of mastitis, the frequency of cases of infection of the mammary gland caused by MRS has ranged from 1.34 to 47.6%. It is believed that the contact of humans with animals positive for MRS and vice versa favors the transmission of this pathogen among species, contributing to the variation in infection rates. MRS detection can be performed by phenotypic tests, molecular tests or serological tests and control measures must be taken such as the identification of cases, animal segregation, epidemiological study of the infection source of herd and the constant cleanliness and hygiene of the confined environment, equipment and milking utensils. Mastitis cases caused by this pathogen are of great relevance to public health because the ingestion of contaminated and/or derived from milk may trigger the transfer of MRS for human. Thus, a constant warning is required on the epidemiological surveillance in dairy farms.
