Enteric permeability and inflammation associated with day of hatch Enterobacteriaceae inoculation.

ABSTRACT: Early exposure to Enterobacteriaceae may result in inappropriate microbial colonization of the gastrointestinal (GI) tract, induce mild GI inflammation, alter immune system development, and predispose poultry to opportunistic infection. Four experiments were conducted to test Enterobacteriaceae isolates Escherichia coli LG strain (LG), E. coli Huff strain (Huff), Salmonella Enteritidis LB (SE) and Salmonella Typhimurium (ST) on ability to induce GI inflammation. All 4 experiments included a noninoculated control, and day of hatch (DOH) oral inoculation of LG, Huff, SE and ST in experiment 1, LG and SE in experiment 2, and LG, Huff, SE, and ST in experiment 3. Experiment 4 included LG, Huff, a noninoculated control (NIC), and Clostridium perfringens only (NCP) wherein birds received oral C.
