3.2. Global diversity of intestinal microbial communities across all treatment groups
A total of 49,031 16S rRNA sequences were generated from the contents of the intestinal ileum of unsupplemented/uninfected (control), unsupplemented/co-infected (NE), and leoresin supplemented/co-infected (NE + XT) Cobb, Hubbard, and Ross chickens (Table 1). Individual pyrosequencing reads corresponding to specific OTUs were assigned to bacterial phyla and genera by homology comparison using the RDP and Silva databases. Table 2
