Table 1.
Description of isolates included in the study. Species distribution and number of sero-ribotypes among isolates from human cases, retail food samples (mainly chicken and turkey products) and broiler chickens at slaughter. No species distribution is given for pigs and cattle as isolates from these sources were selected differently (only C. jejuni isolates were included, and these were from the whole country)
No information regarding travel was available for 297 of the human isolates.
For thee food isolates the country of origin was not registered.
Only C. jejuni were selected from cattle and pigs.
Not speciated or C. lari (one domestic human isolate).
Typable with both typing methods: serotyping and RiboPrinting.
Average number of isolates per subtype; subtype is defined as combined serotype and ribotype.
The discriminatory index, calculated as described by Hunter & Gaston [16], shows the probability of the typing system to assign different types to two unrelated strains.
