영문 초록

This study was conducted to investigate the colonization characteristics of Listeria monocytogenes in chickens. A total of 70 chickens were challenged orally with either 10², 10⁴, and 10⁶ cells of L. monocytogenes strain Scott A (serotype 4b) and wild strain(serotypel) at newly hatched chicks. Seven days after the challenge, the cecum, duodenum, spleen, liver and cloacal swabs were sampled from each chick and were analysed for the presence of L. monocytogenes. Serotype 4b strain was a dose-related colonization response(10⁶＞10²) ; and more recoveries were obtained from the cecum, duodenum and cloacal swabs than from the spleen and liver. L. monocytogenes was discharged(1.0-5.7 CFU log₁₀) for 7 days after the challenge, and after that, organisms were not recovered from any cloacal swabs.
