Aims: The efficiency of eight enrichment broths for the selective isolation of Campylobacter jejuni was compared to identify an optimal enrichment broth. Methods and Results: Brucella-FBP, Preston, Doyle and Roman, modified CCD (mCCD), Park and Sanders, Bolton, Hunt and Radle and Hunt broths were compared for their recovery of (i) Camp. jejuni in suspension, (ii) Camp. jejuni from inoculated ground pork, (iii) heat-injured Camp. jejuni (55°C for 20 min) in suspension and (iv) heat-injured Camp. jejuni from inoculated ground pork. Hunt broth and Bolton broth showed the highest and most rapid enrichment efficacy for the cell suspensions and ground pork, respectively. Preston, Park and Sanders and mCCD broths had relatively high enrichment efficiencies, while Brucella-FBP broth was significantly inferior to the other broths (P < 0·05). Conclusions: Cell recovery from the eight enrichment broths was dependent on the sample type and the state of the cells. The use of the appropriate broth is important for the rapid and efficacious enrichment of Camp. jejuni. In particular, heat-injured Camp. jejuni require a longer cultivation time and a suitable enrichment broth. Significance and Impact of the Study: The results from the present study provide information for selecting the most appropriate enrichment broth for Camp. jejuni and may contribute to improved detection methods for the organism.
