Journal ArticleDOI

Diversity and phylogenetic analysis of bacteria in the mucosa of chicken ceca and comparison with bacteria in the cecal lumen

Jianhua Gong, +6 more
- 01 Feb 2002 - 
TL;DR: Bacteria in the mucosa were highly diverse but mainly Gram-positive with low G+C and Fusobacterium prausnitzii and butyrate-producing bacteria comprised the largest groups among 116 cloned sequences.
Journal ArticleDOI

Molecular analysis of bacterial populations in the ileum of broiler chickens and comparison with bacteria in the cecum

Jianhua Gong, +6 more
- 01 Sep 2002 - 
TL;DR: Comparative studies by T-RFLP and sequence analyses indicated a less diverse bacterial population in the ileum (mucosa and lumen) than in the cecum, which may have good potential in the development of novel probiotics for poultry.
Journal ArticleDOI

Effects of zinc bacitracin, bird age and access to range on bacterial microbiota in the ileum and caeca of broiler chickens

Joshua Gong, +6 more
- 01 May 2008 - 
TL;DR: Determining the effects of zinc bacitracin, bird age and access to range on bacterial microbiota in the ileum and caeca of broilers is investigated.
Journal ArticleDOI

The gene encoding xylulose-5-phosphate/fructose-6-phosphate phosphoketolase (xfp) is conserved among Bifidobacterium species within a more variable region of the genome and both are useful for strain identification.

Xianhua Yin, +4 more
- 01 May 2005 - 
TL;DR: Oligonucleotide sequences from the conserved and variable xfp regions were used as PCR primers, in combinations of appropriate specificity, for the detection and identification of Bifidobacterium isolates.
Journal ArticleDOI

Contributions of O Island 48 to Adherence of Enterohemorrhagic Escherichia coli O157:H7 to Epithelial Cells In Vitro and in Ligated Pig Ileal Loops

Xianhua Yin, +6 more
- 15 Sep 2009 - 
TL;DR: The data suggest that Ter, Iha, and urease may contribute to EHEC O157:H7 pathogenesis by promoting adherence of the pathogen to the host intestinal epithelium.
