The cellular fatty acid profiles of newly described campylobacters were determined on a polar, capillary cQlumnI. Six isolates of the gastric spiral organism, Campylobacter pylori subsp. mustelae, from ferrets from Australia, England, and the United States were all found to have a similar fatty acid profile which was different from that of C. pylori from humans; C. pylori subsp. mustelae did not have 3-hydroxyoctadecanoic acid (3-OH C18:0) and had much less tetradecanoic acid (C14:0) and much more hexadecanoic acid (C16:0). Inasmuch as

The heterogeneous oxidation of sulfides and selenides by copper(II) permanganate octahydrate or a mixture of potassium permanganate and copper(II) sulfate pentahydrate has been studied. Conditions under which quantitative conversions of the sulfides and selenides to the corresponding sulfones and selenones take place have been determined and an attempt has been made to visualize a mechanism for the reaction.
