Characterization of Campylobacter jejuni from Norwegian broilers

Characterization of Campylobacter jejuni originating from Norwegian broiler farms with recurrent Campylobacter spp. positive flocks and from broiler farms with sporadic detection of Campylobacter spp. Comparison of isolates from the same farm to detect possible persistence of Campylobacter jejuni over time, and comparison of isolates from "case" and "control" farms to detect possible genetic traits associated with isolates detected from flocks at farms with recurrent Campylobacter jejuni detections.
