The aim of our paper is to expose microbiological and epidemiological situation regarding campylobacters in humans and broilers in Slovenia in the period 2007-2011, and to compare data on antimicrobial resistance of human and broiler C. jejuni isolates. The incidence of campylobacteriosis in humans in Slovenia is increasing since 2008 and is all the time superior to European average. In 2010 it was 49.9 cases per 100,000 population. The rate of campylobacter colonization in broilers, chicken carcass contamination and meat contamination ranged from 73% to 88%, 81% to 93% and 49% to 79%. Resistance of human and poultry C. jejuni isolates has always been very low against gentamicin and erithromycin. Resistance to tetracycline was moderate to high in humans and very high in poultry. Resistance to ciprofloxacin has been very high and stable in humans and is particularly high in broilers. High campylobacter colonization rate in broilers, high proportion of contaminated carcasses and chicken meat and extremely high C. jejuni resistance to ciprofloxacin in humans and broilers have become a problem in Slovenia.
There is a concern that widespread use of biocides is responsible for the selection and maintenance of antibiotic-resistant bacteria. For 42 Campylobacter strains from food, water, animal and human sources in Slovenia, different antibiotic and biocide resistance levels were determined. However, this study does not provide evidence to confirm that tolerance to biocides is connected to antibiotic resistance in Campylobacter.
