∗Putative virulence proteins were identified using mass spectrometry analysis.
SC: the value of the mean spectral counts from four replicates with standard deviation. The SC values of virulence proteins in C. concisus P6CDO-S1 strain cultured under AnaeroH2+ and AnaeroH2− conditions were not significantly different (P > 0.05).
AnaeroH2+: anaerobic condition with H2.
AnaeroH2−: anaerobic condition without H2.
P6CDO-S1 strain is an oral strain isolated from a patient with CD.
