Resistência de Staphylococcus coagulase positiva e Streptococcus sp. isolados do leite de vacas com mastite clínica na bacia leiteira de Goiânia. Anais da Escola de Agronomia e Veterinária, Goiânia, v. 27, n. 2, p. 61-68, jul./dez. 1997.

Toe diffusion method was used in plate of Kirby-Bauer, being tested ten active principies used in cases of clinicai mastitis. Natural penicillin, chloranphenicol, tetraciclyne, kanamicyn, gentamicyn, nitrofurantoin, trirnetopryn + sulfametoxazol, enrofloxacyn, perlimicyn and ceftiofur were tested. Toe samples of Staphylococcus coagulase positive presented a spectrum of larger resistance for the penicillin (78,9%), followed by trirnetoprirn + sulfametoxazol (59,2%) and nitrofurantoin (57,8%). Toe largest susceptibilitys frequency was found in enrofloxacyn (96%), in perlirnicyn (94%) and in ceftiofur (94%). For the samples of Streptococcus sp. there was a profile resistance for penicillin (92%), chloranphenicol (74,5%) and trimetoprirn + sulfametoxazol (52%). A sensibility profile was also verified for enrofloxacyn (96%), ceftiofur (92%) and perlirnicyn (92%).porAcesso AbertoMastite bovinaSensibilidadeResistênciaBovine mastitisResistanceSusceptibilitiesArtigo
