Background: Uncovering the taxonomic composition and functional capacity within the swine gut microbial consortia is of great importance to animal physiology and health as well as to food and water safety due to the presence of human pathogens in pig feces. Nonetheless, limited information on the functional diversity of the swine gut microbiome is available. Results: Analysis of 637, 722 pyrosequencing reads (130 megabases) generated from Yorkshire pig fecal DNA extracts was performed to help better understand the microbial diversity and largely unknown functional capacity of the swine gut microbiome. Swine fecal metagenomic sequences were annotated using both MG-RAST and …

Identification and quantification of phylogenetically defined bacterial populations in the environment are often performed using molecular tools targeting 16S rRNA. Fluorescence in situ hybridization has been used to monitor the expression and processing of rRNA by targeting the 3' tail of precursor 16S rRNA. To expand this approach, we employed reverse transcription of total RNA using primer S-D-Bact-0338-a-A-18. Length heterogeneity detected by slab gel analysis, denaturing high-performance liquid chromatography (DHPLC) was used to differentiate the 5' tail of the precursor from mature 16S rRNA, and the relative abundance of the precursor compared to the abundance of mature 16S rRNA was …
