Abstract

Distribution of Campylobacter jejuni in wild birds and serogroup of isolates by slide agglutination technique.

Abstract

Thermophilic campylobacters were isolated from 55 (7.9%) of the 700 birds examined. By species, they were detected in 51 (13.5%) of 378 feral pigeons, 2 (2.4%) of 82 pintails and 3 (60.0%) of 5 sparrows. In pigeons, large differences were demonstrated in the detection rates, depending on the site of capture and even among the groups captured in the same area, varying from zero to 50.0%. All the strains isolated from pigeons and sparrows were C. jejuni. Two strains isolated from pintails were identified as C. coli, while no C. laridis was detected. Seventeen (34.7%) of 49 strains of C. jejuni isolated from feral pigeons and 2 strains (100.0%) from sparrows were serotyped by slide agglutination. TCK 20 was frequently found in feral pigeons. Two strains of C. coli isolated from pintails were not serotyped by any of the antisera to C. jejuni.
