Abstract:
Mastitis is a complex disease and is considered one of the main causes of losses to the global dairy industry. The objective of this review was to compile information for the last ten years of mastitis in ruminants in Brazil. The prevalence of subclinical mastitis was 48.64% in cattle, 30.7% in goats, 31.45% in sheep and 42.2% in the buffalo species, with especial participation of Staphylococcus spp. in the etiology. Risk factors associated with the occurrence of mastitis were related to problems in environmental sanitation and handling of animals. The largest percentage of resistance of microorganisms to antimicrobials was for penicillin, ampicillin, amoxicillin and neomycin. The use of molecular tools for diagnosis of mastitis-causing agents in the country is still scarce, making it difficult to obtain a faster, sensitive and specific diagnosis.
