The fate of Listeria monocytogenes in chicks perorally dosed with these bacteria at 2 days of age was determined by bacterial enumeration, immunoperoxidase staining and histological examination of the liver, muscle and gastrointestinal tract. Results revealed listerial egress from the digestive tract and elimination of the organism from the body in most of the chicks within 9 days post-inoculation. L. monocytogenes was isolated from the caecum of only one of 10 chicks examined at 4 weeks post-inoculation. Results indicate that chickens are not likely to be common reservoirs of L. monocytogenes. Intestinal carriage of L. monocytogenes by poultry may frequently be transient, resulting from ingestion of Listeria-contaminated feed and soil.
通过细菌计数、免疫过氧化物酶染色以及对肝脏、肌肉和胃肠道进行组织学检查，确定了2日龄雏鸡经口接种这些细菌后，单核细胞增生李斯特菌在雏鸡体内的命运。结果显示，在接种后9天内，大多数雏鸡体内的李斯特菌从消化道排出并被机体清除。在接种后4周检查的10只雏鸡中，只有1只的盲肠中分离出了单核细胞增生李斯特菌。结果表明，鸡不太可能是单核细胞增生李斯特菌的常见宿主。家禽肠道携带单核细胞增生李斯特菌可能经常是短暂的，这是由于摄入了受李斯特菌污染的饲料和土壤所致。
