Comparative Genomics and Virulence Mechanisms to Identify Genes Related to Mucin O-Glycan Degradation and Pathogenicity in a Potentially Multidrug-Resistant Clostridium tertium Strain.

ABSTRACT: Clostridium tertium is a pathogenic bacterium that directly colonizes the gastrointestinal mucosa, causing inflammation and neutropenia. The virulence factors and pathogenic mechanisms of C. tertium are not well known. In this study, C. tertium HGMC01 was isolated by enrichment culture of human feces, and its whole chromosome genome was sequenced without extra plasmids. C. tertium HGMC01 had a larger genome and a higher gene count compared with five other C. tertium strains. A pangenome analysis of six strains showed that C. tertium HGMC01 had the highest number of unique genes and the lowest number of accessory genes clustered phylogenetically with C. tertium src5, a strain of animal origin. C. tertium HGMC01 genome showed a variety of secreted glycoside hydrolases and carbohydrate-bindin
