Abstract

The lipids of different species of Helicobacter (H. felis, H. muridarum, H. mustelae, H. fennelliae, and H. cinaedi) were studied. Different types of cholesteryl glucosides were found in all of the species studied except H. cinaedi. The total amount of cholesteryl glucosides varied from 14.8% of total lipids in H. mustelae to 33.1% of total lipids in H. felis. The different types of cholesteryl glucosides and their species distribution are cholesteryl-6-O-acyl-α-D-glucopyranoside (cholesteryl-6-O-tetradecanoyl-α- D-glucopyranoside in H. felis and cholesteryl-6-O-dodecanoyl-α-D- glucopyranoside in H. muridarum), cholesteryl-α-D-glucopyranoside (H. felis, H. muridarum, H. mustelae, and H. fennelliae), and cholesteryl-6-O- phosphatidyl-α-D-glucopyranoside (H. fennelliae). The neutral lipid fractions showed a high percentage of cholesterol, with selective accumulation of free cholesterol. The study thus shows that the characteristic presence of steryl glycosides in Helicobacter spp. may be an important chemotaxonomic marker for many of the species, and the helicobacters show a selective accumulation of free cholesterol from the media.
