Abstract

It was verified the spectrum of susceptibilities/resistance of 76 samples of Staphylococcus coagulase positive and 51 samples of Streptococcus sp., isolated from milk of 231 cows presenting clinical mastitis. The diffusion method was used in plate of Kirby-Bauer, being tested ten active principles used in cases of clinical mastitis. Natural penicillin, chloranphenicol, tetraciclyne, kanamicyn, gentamicyn, nitrofurantoin, trimetopryn + sulfametoxazol, enrofloxacyn, perlimicyn and ceftiofur were tested. The samples of Staphylococcus coagulase positive presented a spectrum of larger resistance for the penicillin (78.9%), followed by trimetoprim + sulfametoxazol (59.2%) and nitrofurantoin (57.8%). The largest susceptibility frequency was found in enrofloxacyn (96%), in perlimicyn (94%) and in ceftiofur (94%). For the samples of Streptococcus sp. there was a profile resistance for penicillin (92%), chloranphenicol (74.5%) and trimetoprim + sulfametoxazol (52%). A sensibility profile was also verified for enrofloxacyn (96%), ceftiofur (92%) and perlimicyn (92%).
