Comparative efficacy of liquid enrichment medium for isolation of Campylobacter jejuni

Isolation of Campylobacter jejuni from 1,249 human fecal specimens by direct inoculation on selective Columbia agar and liquid enrichment medium was compared. The use of liquid enrichment medium provided a 30% higher isolation rate of C. jejuni. The overall isolation rate achieved by using direct plating and enrichment together was 8.2%.
