Sažetak
Bacteria Campylobacter spp. are the leading causes of acute bacterial gastroenteritis all over the world. Most of the human outbreaks are related to preparation and/or consummation of poorly cooked poultry meat. Overuse of different antibiotics in poultry production caused increasing number of resistant strains that could be also transmissioned to human. The antimicrobial susceptibility to azithromycin, ciprofloxacin, enrofloxacin, erythromycin, gentamicin and tetracycline of altogether 56 C. jejuni and C. coli strains isolated from 616 samples of poultry of different species, age and production type were detected by using three methods –disc diffusion, agar dilution and E test. The highest in vitro resistance by using disk diffusion method was observed to azithromycin (from 90.9% up to 100%), erythromycin (from 63.3% up to 65.4%), but also to tetracycline (from 65.4% to 76.6%) and gentamycine (from 11.1% up to 62.5%). The study determined also the high frequency of resistant Campylobacter strains (from 40% to 43.3%) to enrofloxacin and ciprofloxacin. Altogether 20 strains were multiresistant, to two or more antibiotics. Out of them, four C. jejuni strains isolated from toms, two from parent turkey flocks and 12 strains isolated form broilers of 10 weeks of age were resistant to all five antibiotics. The highest sensitivity was observed to gentamycin and eritromycin. Correlation between disk diffusion and agar dilution method revealed statistically significant results, and disk diffusion method can be used as relevant for the antimicrobial susceptibility testing. High percentage of resistant strains to all antibiotics tested, revealed the uncontrolled use of medicaments in poultry production. Antimicrobial agents will continuously be used in human and veterinary medicine, but it should be judiciously and under control, together with routinely susceptibility testing.
