Abstract: The mastite in its subclinica form is the responsible one for the biggest losses of milk production representing raised economic damages. With the objective to study the etiology of the bovine subclinica mastite in the city of Parauapebas-Pará, they had been submitted to California Mastitis test. - CMT 174 (8.4%) cows in its majority crossbred, pparently healthful of 15 located milk properties in the related city, situated in the Southeastern Mesorregião of the state of Pará. ++ were observed that 84 (48.33%) animal ones had presented resulted of +, +++ to the CMT. The milk of each ceiling that had reacted to the CMT in a total of 178 samples was analyzed bacteriologically aiming at the isolation and the identification of the microorganisms, had been analyzed the macrocospic, microscopical characteristics and biochemists of the isolated cultures. Of the total of samples 208 had been isolated cepas of microbianos agents in pure cultures or in associations being all proceeding ones from mamitico milk, of which 141 (67.79%) cepas was positive coconuts Gram S.aureus (29%) and S.epidermidis (19.14%) and 67 (32.21%) were enterobactérias.
