Abstract
Venereal campylobacteriosis is associated with infection of Campylobacter fetus subsp. fetus and Campylobacter fetus subsp. venerealis. The etiological agent is transmitted by natural bull breeding or artificial insemination using contaminated semen. The present study aimed to determine the in vitro susceptibility of C. fetus subsp. venerealis isolates to antimicrobial drugs generally used in clinical and semen treatment. Reference strains of C. fetus subsp. fetus and C. fetus subsp. venerealis and 21 C. fetus isolates were tested. The susceptibility test was performed by using the modified Kirby-Bauer diffusion disc method. C. fetus subsp. fetus reference strain was resistant to lincomycin and penicillin. C. fetus subsp. venerealis was susceptible to all antimicrobial tested, with exception to C.C. KrewerDnalidixic acid. C. fetus subsp. venerealis samples were sensible to amikacin, ampicillin, cefalotin, streptomycin, gentamycin, penicillin and tetracycline. Drug resistance was observed on 42.86% of lincomycin, 4.76% of enrofloxacin, and 100% to nalidixic acid. In addition 4.76% of the isolates showed intermediate susceptibility to enrofloxacin, neomycin, polimixin B and 9.52% to lincomycin. The susceptibility of C. fetus isolates to antimicrobial drugs commonly used in clinical and semen treatment was demonstrated.
