Campylobacter jejuniin Black-Headed Gulls ( Larus ridibundus): Prevalence, Genotypes, and Influence on C. jejuni Epidemiology
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...
