Chicken-to-Human Infection with Campylobacter jejuni and Campylobacter coli : Biotype and Serotype Correlation.

Isolates of Campylobacter jejuni and Campylobacter coli isolated from two flocks of parent hens and their progeny which were followed from hatch to slaughter in 10 different farms within a 6-month period in the area of Ljubljana, Yugoslavia were bio- and serotyped. They were compared to those isolated from diarrheic patients within the same period of time. C. jejuni biotype I of Lior's biotyping scheme was found most predominant. Using 25 unabsorbed antisera raised against live C. jejunicoli cultures, 62.2% and 44.8% of the isolates from patients and chickens, respectively, could be serotyped. Penner sergroups (PG) 1, 2, 5, 7, 9, and 22 were found common to both patients and chickens. PG 2 was the most common isolate. PG 8, which was the second most frequently isolated serogroup from patients was not isolated from chickens. No Campylobacters were isolated from 71 farm family members.
