Abstract

The main pathology presented on intensive dairy farms around the world and costing significant economic losses to the farmer mas. Despite handling good asepsis and antisepsis protocols of milking teams and staff, cases of bovine mastitis continue to present a high prevalence and incidence. Mastitis is an inflammation of the mammary gland and its secretory tissues, which leads to a reduction in milk volume, alteration of its composition and an increase in its normal bacterial load. Through the California Mastitis Test (CMT), 418 rooms belonging to 112 cows were evaluated at the Paysandú agrarian station in the city of Medellín Antioquia. From the positive rooms (reactions from traces to clinical cases) samples of milk were taken to isolate the microorganisms that cause cases of bovine mastitis. Negative Staphylococcus coagulasa, Staphylococcus aureus, Enterobacter, Streptococcus uberis, were of the most representative pathogens agents that were isolated in this study; microorganisms were presented in smaller amount as Streptococcus no agalactiae, Corynebacterium spp, Enterococcus, Streptococcus agalactiae, Citrobacter, E. coli. Subsequently, an antibiogram was performed on persistent cows to mastitis processes in order to implement an adequate treatment
