Analysis of 16S rDNA and Metagenomic Sequences Revealed Microbial Community and Host-Specific Sequences of Canadian Geese Feces
There is an increasing concern regarding the public health risks associated with waterfowl fecal pollution as a result of the increase in geese populations (Branta canadensis) in or near U.S. and Canadian recreational waters. Currently, there are no methods that can be used to detect this important...

Currently, there are no methods that can be used to detect this important source of pollution in part because of the scarcity of information on waterfowl fecal microbial communities. To address this, the molecular microbial diversity of Canadian geese feces was studied using 16S rRNA gene and metagenome clone libraries. Analyses of the fecal 16S rDNA clones (319) demonstrated that these communities are diverse.

In contrast with mammalian gut systems, only a very small fraction of the 16S rDNA sequences were similar to the Bacteriodetes group. Putative protein-coding sequences (270) were identified using bioinformatic analysis of a total of 354 metagenomic clones. Approximately 40% of the protein-encoding sequences identified could be classified into functional groups. Similarity analyses indicated that a significant fraction of the proteins identified was similar to known proteins in Bacilli, Clostridia and gamma Proteobacteria.
