Campylobacter jejuni sequence types show remarkable spatial and temporal stability in Blackbirds.

Background: The zoonotic bacterium Campylobacter jejuni has a broad host range but is especially associated with birds, both domestic and wild. Earlier studies have indicated thrushes of the genus Turdus in Europe to be frequently colonized with C. jejuni, and predominately with host-associated specific genotypes.

Genetic diversity and host associations in Campylobacter jejuni from human cases and broilers in 2000 and 2008.

Campylobacter jejuni is an important food-borne pathogen, with a global distribution. It can colonize numerous host species, including both domestic and wild animals, but is particularly associated with birds (poultry and wild birds). For human campylobacteriosis, poultry products are deemed the most significant risk factor for acquiring infection.

Multilocus sequence typing and FlaA sequencing reveal the genetic stability of Campylobacter jejuni enrichment during coculture with Acanthamoeba polyphaga.

Low concentrations of Campylobacter jejuni cells in environmental samples make them difficult to study with conventional culture methods. Here, we show that enrichment by amoeba cocultures works well with low-concentration samples and that this method can be combined with molecular techniques without loss of genetic specificity.

Marked host specificity and lack of phylogeographic population structure of Campylobacter jejuni in wild birds.

Zoonotic pathogens often infect several animal species, and gene flow among populations infecting different host species may affect the biological traits of the pathogen including host specificity, transmissibility and virulence. The bacterium Campylobacter jejuni is a widespread zoonotic multihost pathogen, which frequently causes gastroenteritis in humans. Poultry products are important transmission vehicles to humans, but the bacterium is common in other domestic and wild animals, particularly birds, which are a potential infection source.

We evaluated the occurrence of three Campylobacter species--C. jejuni, C. coli, and C.

Campylobacter jejuni colonization in wild birds: results from an infection experiment.

Campylobacter jejuni is a common cause of bacterial gastroenteritis in most parts of the world. The bacterium has a broad host range and has been isolated from many animals and environments. To investigate shedding patterns and putative effects on an avian host, we developed a colonization model in which a wild bird species, the European Robin Erithacus rubecula, was inoculated orally with C.

Amoebae and algae can prolong the survival of Campylobacter species in co-culture.

Several species of free-living amoebae can cause disease in humans. However, in addition to the direct pathogenicity of e.g.

Multilocus sequence typing of Campylobacter jejuni from broilers.

Campylobacter jejuni isolates from a national Swedish Campylobacter monitoring in broilers were characterized by multilocus sequencing typing (MLST) in order to study the genetic diversity of this bacterial population. Isolates were initially characterized by pulsed-field gel electrophoresis (PFGE). One hundred were chosen for MLST genotyping.
