To verify the dynamics of antimicrobial resistance in a property in Santa Maria da Boa Vista city - Pernambuco were evaluated 14 Staphylococcus epidermidis isolates from goats with subclinical mastitis. The profile of antimicrobial resistance was determined by disk diffusion test. The genotyping was performed using the marker REP (Repetitive Extragenic Palindromic) - PCR, using RW3A primer, where the degrees of similarity and clustering phenogram were established by means of the Sorensen-Dice coefficient (SD) algorithm UPGMA, program NTSYS-pc, which allowed the identification of 4 patterns of 14 S. epidermidis isolates, being eight in the profile A, four in a profile B, one in profile C and one in profile D. For all groups to penicillin resistance was observed, while for groups A and C this was associated with lincomycin, for group B this was associated with tetracycline.
