3.4. Putative Virulence Proteins Expressed by C. concisus P6CDO-S1 Strain Cultured under AnaeroH2− and AnaeroH2+ Conditions
Proteins expressed by strain P6CDO-S1 under AnaeroH2+ and AnaeroH2− conditions were subjected to mass spectrometry analysis. A number of putative virulence proteins such as fibronectin-binding protein, outer membrane protein (Omp), protease htpx, S-layer-RTX protein, hemagglutinin/hemolysin-related protein, CjaC, and EvpB family type VI secretion protein were identified. The expression levels of these putative virulence proteins, indicated by the spectral counts, were not statistically different when C. concisus strain P6CDO-S1 was grown under AnaeroH2+ and AnaeroH2− conditions (Table 3).
