Abstract:
Salmonella enterica serovar Enteritidis (S. Enteritidis) can colonize in the intestinal tract of chickens and transmit to humans. In order to decrypt the mechanism of avian resistance to S. Enteritidis, we utilized two China local chicken breeds to generate the reciprocal crosses (the Cross and the Reverse-cross). The two lines of hybrids were orally inoculated with S. Enteritidis at 2-day old and sampled at 3 days post-inoculation. Along the analysis direction of multi-omics, differential metabolites, functional pathways and correlated microbes, we found that 12 species of microbes thrived upon S. Enteritidis challenge and probably contributed to the intestinal stability in the Cross by enhancing the production of phenylpropanoids. Our findings can help to understand the symbiotic and resistant mechanisms derived from the intestinal microbiota.
