Sphingolipid composition in Bacteroides species.
Sphingolipid profiles of strains from species of genus Bacteroides, and representative strains from Prevotella and Porphyromonas, were analyzed by thin-layer chromatography and infrared spectrophotometry. Two major types of phosphosphingolipid, ceramide phosphorylethanolamine and ceramide phosphorylglycerol, were detected in B. fragilis, B. ovatus, B. uniformis, B. caccae, B. eggerthii, B. thetaiotaomicron, and B. stercoris, but not in B. merdae, B. distasonis, and B. vulgatus. Strains from the genera Prevotella and Porphyromonas also contained these two sphingolipids. These sphingolipid profiles were conserved within the species tested, and may be useful for differentiation and recognition of relationships within the genera Bacteroides, Prevotella and Porphyromonas.
