A subclinical mastitis study was conducted in nine dairy goat herds in the semi-arid region of Paraíba state, Northeastern Brazil, to determine the occurrence of infection, to evaluate microbiological and cellular profiles of the milk, to test the sensitivity of isolated microorganisms to antimicrobials, and to identify risk factors. One hundred thirty-one dairy goats were used, 261 samples were collected for microbiological culture and 131 samples for somatic cells count (SCC). During collection, the California Mastitis Test (CMT) was conducted and an epidemiological questionnaire was applied for each herd. There was bacterial growth in 30 samples (11.49%), with 25 (83.33%) coagulase-negative Staphylococcus and five (16.66%) Staphylococcus aureus isolated. The SCC mean was 1.39x10 6 cells/ml. CMT presented low sensitivity (46.7%) and low specificity (60.6%) compared with microbiological culture. Gentamicin and the association of neomycin, bacitracin and tetracyclin were the antimicrobials against which the microorganisms isolated showed 100% sensitivity. Penicillin and ampicillin had the greatest resistance rates (66.67% and 63.89%, respectively). Goat breeding is not the main activity on the farms and do not isolate diseased animals were identified as risk factors for caprine subclinical mastitis. Program for the control and prophylaxis of mastitis must be implemented focusing primarily on hygiene cares at milking and correction of the risk factors identified in this study.
