There were collected 4.329 milk samples of all cows in lactation. Previously sampling, there were realized clinical exams of udder, strip cup test and California Mastitis Test (CMT). There were isolated microorganisms as: Staphylococcus aureus, 131 (26.28), Staphylococcus sp. coagulase negative (SCN), 114 (23.22%), Streptococcus agalactiae, 6 (1.22%), Streptococcus sp. esculin positives (ESCPOS), 82 (16.70%), Streptococcus sp. esculin negatives (ESCNEG), 37 (7.54%), Corynebacterium sp. 90 (18.33%), Pseudomonas 5 (1.02%) and yeasts, 26 (5.29%). In total, there were isolated 491 microorganisms, being 381 from infections caused by single pathogen and 10 from multiple agents. Three thousand seven hundred fifth seven milk samples were classified as negative according microbiologic exams, and in 70 (1.62%) samples, it were not possible isolation and microbiological identification due contamination problems.
