一日龄雏鸡通过饲料或直接口服接种沙门氏菌，这是无论是侵入性或非侵入性（血清型鼠伤寒和Kedougou，分别）。经口接种沙门氏菌的鸡消化道和内脏器官的定植速度更快。血清型鼠伤寒沙门氏菌与饲料激发的鸟类相比。相比之下，S.血清型Kedougou仍然局限于消化道。在经口或饲料接种的鸡中，S.通过免疫染色在盲肠固有层中鉴定出鼠伤寒血清型，但未鉴定出Kedougou血清型。电子显微镜检查证实微生物在巨噬细胞内。
Day-old chicks were inoculated either via the feed or by direct oral inoculation with salmonellas which were either invasive or non-invasive (serotypes Typhimurium and Kedougou, respectively). Colonization of the alimentary tract and visceral organs, determined by microbiological examination, occurred more quickly in birds inoculated orally with S. serotype Typhimurium compared with feed-challenged birds. By contrast, S. serotype Kedougou remained confined to the alimentary tract. In birds inoculated either orally or via the feed, S. serotype Typhimurium, but not serotype Kedougou, was identified in the lamina propria of the caecum by immunostaining. Electron microscopic examination confirmed that the organisms were within macrophages.
