Dynamics of leucocyte infiltration and bacterial invasion in the caecal wall were studied after oral infection of 2-day-old chicks with Salmonella enterica ser. Enteritidis. Bacteria invaded the lamina propria of the caecal wall from 12h post-challenge onwards. Bacteriological examination of internal organs (liver, spleen) showed a peak in Salmonella bacteria at 3days post-infection, after which the number of bacteria decreased. Immunohistochemistry revealed macrophages and T-lymphocytes invading the caecal propria mucosae from 24h after challenge onwards, while B-lymphocytes came somewhat …
