Universidade Federal de Minas Gerais, Escola de Veterinária, Departamento de Medicina Veterinária Preventiva, Laboratório de Bacteriologia AplicadaSusceptibility pattern of 45 Campylobacter spp.isolates – 16 C. jejuni, eight C. coli, and 21 C. fetus isolated from different animal species in Brazil – to twelve antimicrobial agents was determined. All Campylobacter spp. isolates were susceptible to gentamicin, sulfadiazine, and sulfamethoxazole. C. jejuni and C. coli were also sensitive to chloramphenicol, whereas all C. fetus strains were susceptible to kanamycin. Cefoperazone showed the highest percentage of resistance among C. jejuni (68.75%), followed by nalidixic acid (31.25%), ampicillin (37.50%), tetracycline (37.50%), erythromycin (12.50%), and kanamycin (6.25%). Likewise, cefoperazone exhibited the highest percentage of resistance among C. coli (75.00%), followed by nalidixic acid (50.00%), tetracycline (50.00%), erythromycin (37.50%), ampicillin (12.50%), and kanamycin (12.50%). Among C. fetus strains, nalidixic acid showed the highest resistance rate (85.71%), followed by cefoperazone (71.43%), tetracycline (42.86%), ampicillin (19.05%), chloramphenicol (9.52%), and erythromycin (4.76%). Therefore, it was found that the majority of Campylobacter spp. isolated from animals was sensitive to gentamycin, chloramphenicol, kanamacyn, and sulfonamides; however, a high proportion of the strains showed reduced susceptibility to nalidixic acid, ampicillin, cefoperazone, and tetracycline. Moreover, C. coli and C. fetus isolates showed a high percentage of multidrug resistant strains.
