[Microbiology of Campylobacter pylori]

Campylobacter pylori is a hitherto unknown spiral bacterium. It is implicated in the pathogenesis of chronic antral type B gastritis and also of duodenal and gastric ulcer disease. However, its causal role has not yet been unequivocally established. Taxonomically, C.pylori appears to belong to a genus different from genuine campylobacters, but a precise classification is likewise lacking. The in vitro sensitivity analyses of various antibiotics are complicated by a number of technical difficulties. This is one of the reasons, that results of in vivo eradication trials have to be interpreted with considerable caution.
