Colonization of gastrointestinal tracts of chicks by Campylobacter jejuni.

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