Abstract

The study was carried out in the region of Placas, Pará. Objective: identify the main causing agents of mastitis, as well as evaluating the resistance profile of the isolated agents against antimicrobials. Methods: Ten properties were evaluated, where 161 animals were submitted to the California Mastitis Test (CMT) for the diagnosis of subclinical mastitis, and milk samples were collected from positive animals and led for culture and antibiogram. Results: In total, 31.06% of the animals were positive for CMT. The main agents identified were Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae and Streptococcus bovis. The antibiogram indicated resistance to Penicillin, Ceftazidime and Cephalothin. Conclusion: The properties surveyed showed a high rate of subclinical mastitis, regarding antimicrobial resistance, in general, all agents showed high resistance.
