RESUMO
Bacterial enumeration and histologic examination of organs and tissues of 8-day-old chicks 7 days after peroral inoculation with Campylobacter jejuni revealed that the organism colonized primarily the lower gastrointestinal tract. The principal sites of localization were the ceca, large intestine, and cloaca, where densely packed cells of C. jejuni were observed in mucus within crypts. Examination of C. jejuni-colonized crypts by transmission electron microscopy revealed that the campylobacters freely pervaded the lumina of crypts without attachment to crypt microvilli. Understanding the mechanism of colonization may lead to approaches that will reduce the incidence of C. jejuni carriage by poultry.
