Experimental infection of broiler chickens with Campylobacter jejuni

Abstract

Introduction Campylobacteriosis is recognized as the most common foodborne bacterial zoonosis worldwide. The species most frequently involved in cases of gastroenteritis in humans is Campylobacter jejuni, followed by Campylobacter coli. Transmission to humans typically occurs through the consumption of contaminated poultry meat. This study aimed to perform an experimental infection assay in broiler chickens with C. jejuni to evaluate its excretion dynamics, cecal invasion, and colonization of internal organs.
