A sample was considered presumptive Campylobacter positive when samples cultured on mCCDA and BA produced colonies with typical Campylobacter morphology and at least one isolate was positive by the Campylobacter genus PCR.
A sample was considered C. jejuni positive when at least one isolate from that sample was confirmed as C. jejuni by PCR.
