Abstract:
A procedure for direct detection of Campylobacter in feces has been developed using a biotin-labelled DNA probe. A species-specific probe (Bio-pCJ174 probe) for C. jejuni and a multivalent probe (Bio-pooled probe) for the thermotolerant Campylobacter species were developed with Bio-11-dUTP. Both probes were used to detect Campylobacter in 100 specimens of chicken feces. The coincidence rate of the results obtained by the Bio-pooled probe and cultivation was 90% and that of the Bio-pCJ 174 probe and cultivation was 96%. Identification of isolates was also carried out with both probes.
