Campylobacter jejuni in black-headed gulls (Larus ridibundus): Prevalence, genotypes, and influence on C. jejuni epidemiology
(2002) In Journal of Clinical Microbiology 40(12). p.4594-4602- Abstract
- Campylobacteriosis is a zoonotic disease in which birds have been suggested to play an important role as a reservoir. We investigated the prevalence of Campylobacter jejuni subsp. jejuni in black-headed gulls (Larus ridibundus) in southern Sweden with the aim of examining the nature of C. jejuni infection in this bird species. Birds were sampled in four sampling series each year during 1999 (n = 419) and 2000 (n = 365). Longitudinally sampled C. jejuni isolates from individual gulls were subjected to macrorestriction profiling (MRP) by pulsed-field gel ellectrophoresis to investigate the genotypical stability during the natural course of infection. Furthermore, a subset (n 76) of black-headed gull isolates was compared to isolates from... (More)

Longitudinally sampled C. jejuni isolates from individual gulls were subjected to macrorestriction profiling (MRP) by pulsed-field gel ellectrophoresis to investigate the genotypical stability during the natural course of infection. Furthermore, a subset (n 76) of black-headed gull isolates was compared to isolates from broiler chickens (n = 38) and humans (n 56) originating from the same geographic area. We found a pronounced seasonal variation in C. jejuni carriage, with the highest rates found in late autumn. MRP similarities were higher between isolates of human and broiler chicken origin, than between those of wild bird origin and either of the other two hosts. However, identical MRPs were found in two gull isolates and one human isolate after digestion with two restriction enzymes, strongly indicating that they may have been colonized by the same clone of C. jejuni. The MRPs most prevalent in gull isolates did not occur among isolates from humans and broiler chickens, suggesting the existence of a subpopulation of C. jejuni adapted to species-specific colonization or environmental survival.
