Campylobacter Enrichment Broth Base (Preston Enrichment Broth Base) is recommended for selective enrichment and cultivation of Campylobacter species. This medium is recommended by APHA for enrichment of thermotolerant Campylobacter species from foods. It has a rich basal medium to aid resuscitation of sublethally damaged Campylobacter. Preliminary incubation of the medium complete with antibiotics for 4 hours at 37deg C was recommended to aid resuscitation of injured organisms followed by 42deg C for 18-48 hours.
