Observations supporting hypothetical commensalism and competition between two Campylobacter jejuni strains colonizing the broiler chicken gut.

ABSTRACT: Campylobacter jejuni is the most prevalent bacterial foodborne pathogen in humans. Given the wide genetic diversity of C. jejuni strains found in poultry production, a better understanding of the relationships between these strains within chickens could lead to better control of this pathogen on farms. In this study, 14-day old broiler chickens were inoculated with two C. jejuni strains (10³ or 10⁷ CFU of D2008b and 10³ CFU of G2008b, alone or together) that were previously characterized in vitro and that showed an opposite potential to compete for gut colonization in broilers. Liver samples and ileal and cecal contents were collected and used to count total C. jejuni and to quantify the presence of each strain using a str
