Pigs are known as the mainCampylobacter colireservoirs. Campylobacteriosis, the most commonly reported gastrointestinal disease in humans, is mainly caused by the consumption of poultry meat, and little is known about the role of pork. Pigs are often associated withC.coli, including antimicrobial-resistant isolates. Therefore, the entire pork production chain must be considered as an important source of antimicrobial-resistantC.coli. This study aimed to determine the antimicrobial resistance ofCampylobacterspp. isolated from caecal samples of fattening pigs at the Estonian slaughterhouse level over a five-year period. The proportion ofCampylobacter-positive caecal samples was 52%. AllCampylobacterisolates were identified asC.coli. A high proportion of the isolates were resistant to most of the studied antimicrobials. The resistance to streptomycin, tetracycline, ciprofloxacin and nalidixic acid was 74.8%, 54.4%, 34.4% and 31.9%, respectively. In addition, a high proportion (15.1%) of the isolates were multidrug-resistant and, in total, 93.3% were resistant to at least one antimicrobial.
