Clostridium difficile contains plasmalogen species of phospholipids and glycolipids.

ABSTRACT: Analysis of the polar lipids of many pathogenic and non-pathogenic clostridia has revealed the presence of plasmalogens, alk-1'-enyl ether-containing phospholipids and glycolipids. An exception to this finding so far has been Clostridium difficile, an important human pathogen which is the cause of antibiotic-associated diarrhea and other more serious complications. We have examined the polar lipids of three strains of C. difficile by thin-layer chromatography and have found acid-labile polar lipids indicative of the presence of plasmalogens. The lipids from one of these strains were subjected to further analysis by liquid chromatography coupled to electrospray ionization-mass spectrometry (LC/ESI-MS), which revealed the presence of phosphatidylglycerol, cardiolipin, monohexosyldiradylglyce
