Background and Objectives: Campylobacter jejuni is one of the most common bacterial cause of diarrheal
disease in humans throughout the world.
Contamination is mainly linked to the consumption of undercooked food products contaminated with
Campylobacters. The most characterized toxin proposed is CDT, which has been detected in several
Campylobacter species. With regard to the role of broiler chickens in transmission of campylobacter to
human and the possible role of CDT in the pathogenesis of Campylobacter, detection of Campylobacter
producing CDT is necessary .
Material and Methods: In this study 368 rectal swabs were collected from chikens . All the specimens were
cultured on Skirrows & Blood agar and incubated in microaerophilic conditions at 42º C for 48-72 h . Hella
cell was applied to detect CDT in C.jejuni and coli.
Results: Campylobacter strains were isolated from 114 (31%) of 368 chicken (101 C. jejuni and 13 C.
coli). Toxin production inC. jejuniand C. coli was 94% and 76.9 % respectively.
Conclusion: It seems that the majority of C.jejuni and C.coli produce CDT although C. jejuni produces a
higher titer.
