Abstract: This research was undertaken to understand the effect of Salmonella enteritidis (SE) on the Enterococcus counts in the gastrointestinal tract of China racing pigeon. Researchers applied a FQ-PCR assay to detect the genomic DNA of Enterococcus which extracted from duodenum, jejunum, ileum, cecum and rectum of 3 weeks old pigeon after orally injection by SE at different time points. The results showed that Enterococcus were consistently detected from all segments of the gastrointestinal tract. It mainly distributed in the cecum of the gastrointestinal tract of pegion. At 12-72 h postinfection there were obviously undulation change of the Enterococcus counts. The Enterococcus populations in the jejunum were decreased at 24 h postinfection (p<0.05). At 6 days postinfection, the residual Enterococcus can re-grow to normal condition. The research indicated that the Enterococcus counts in the gastrointestinal tract were decreased after SE-infected. The residual Enterococcus can re-grow, outcompete SE and thereby re-establish colonization resistance.
