Prevalence of Campylobacter spp. in slaughtered cattle and buffaloes in Vientiane, Lao People's Democratic Republic.

This is the first report regarding isolation of Campylobacter in caecum and bile samples obtained from ruminants in Vientiane, Lao PDR. Campylobacter was isolated from 3 (1.6%) of the 184 caecum samples and 1 (1.0%) of the 100 bile samples obtained from buffaloes. Three of the 4 isolates were determined to be C. jejuni, which was detected in 2 caecum samples and 1 bile sample; the other caecum sample contained C. fetus. Campylobacter was not isolated from any of the 82 cattle caecum samples. Our results suggest that cattle and buffaloes may not be important sources of Campylobacter food poisoning in Lao PDR.
