Autoclaved or non-autoclaved used broiler litter that was experimentally contaminated with Campylobacter jejuni was capable of infecting specific-pathogen-free chicks maintained in modified Horsfall isolators. Artificially infected chicks became fecal shedders of C. jejuni, resulting in contamination of both autoclaved and non-autoclaved used broiler litter. Fecal shedding of C. jejuni by litter-reared, artificially infected chicks persisted for at least 63 days after chicks were transferred to an isolation unit with a wire floor, which prevented coprophagy. C. jejuni was consistently recovered from water and litter in units housing directly and indirectly infected birds, indicating environmental contamination. These experiments demonstrate the potential role of litter in the perpetuation and transmission of C. jejuni infection in commercial chickens.
经实验感染空肠弯曲菌的经高压灭菌或未经高压灭菌的用过的肉鸡垫料，能够感染饲养在改良霍斯福尔隔离器中的无特定病原体雏鸡。人工感染的雏鸡成为空肠弯曲菌的粪便排出者，导致经高压灭菌和未经高压灭菌的用过的肉鸡垫料均受到污染。在用垫料饲养、人工感染的雏鸡转移到带有金属网地板以防止食粪癖的隔离单元后，空肠弯曲菌的粪便排出持续了至少63天。在直接和间接感染鸟类的饲养单元中，始终能从水和垫料中分离出空肠弯曲菌，表明存在环境污染。这些实验证明了垫料在商品鸡空肠弯曲菌感染的持续存在和传播中的潜在作用。
