ABSTRACT
Campylobacter jejuni and C. coli have recently become the most frequent cause of bacterial foodborne enteric infection in most industrialised countries. Consumption and handling of undercooked contaminated poultry meat was identified as an important risk factor for human campylobacteriosis. The aim of this study was to ascertain the genetic diversity of C. jejuni and C. coli strains isolated from poultry in Slovenia. A total of 68 isolates (42 C. jejuni , 26 C. coli ) from faeces (n = 48), meat (n = 15) and skin/carcasses (n = 5) of chicken (n = 60) and turkey samples (n = 5) were analysed by pulsed-field gel electrophoresis. Sma I macrorestriction discriminated between C. jejuni and C. coli isolates. C. jejuni isolates exhibited a higher degree of diversity compared to C. coli isolates. In the C. jejuni group, a number of small clusters were apparent, while C. coli strains formed less but larger clusters. Additional Kpn I digestion of selected isolates resulted in poor subtyping. Strains with identical or very similar profiles were found on different farms, either in the same or different regions and time periods. Some of the clones indicated possible cross-contamination at slaughterhouses.
