Isolation of Campylobacter spp. from pigeon feces by a combined enrichment-filtration technique

A technique combining enrichment in Preston enrichment broth and direct filtration onto chocolate agar was used to isolate Campylobacter species from pigeon feces. Campylobacter jejuni was isolated from 106 of 200 samples tested; 105 strains were isolated by enrichment-filtration, and 84 strains were isolated by direct plating. Most of the strains grew after 48 h at 37 degrees C.
