Microbiological aspects of Helicobacter pylori (Campylobacter pylori).
The human gastric pathogen Campylobacter pylori has recently been reclassified as Helicobacter pylori, and a related spiral bacterium found in the stomach of ferrets has been designated Helicobacter mustelae. The general microbiological features of Helicobacter pylori are delineated here, with details of phenotypic differences between Helicobacter pylori and Helicobacter mustelae; comparisons are made with Wolinella succinogenes and Campylobacter jejuni. The Helicobacter organisms possess an external glycocalyx which can be visualised by electron microscopy, and which may be involved in bacterial adherence. The finding of soluble and cell-associated haemagglutinins of Helicobacter pylori is reported. Detection of Helicobacter pylori in clinical specimens, susceptibility of the organism to antibacterial agents, and other aspects of practical and clinical significance are briefly reviewed.
