Identification of Campylobacter pylori by using the rapID NH system.

Campylobacter pylori has been associated with chronic active antral gastritis. The organism was isolated from 19 of 45 gastric mucosal biopsies on blood agar plates with increased CO2 at 35 degrees C. The RapID NH system, a set of dehydrated substrates for preformed enzymes, was used to assist in the identification of C. pylori. All C. pylori gave the same biochemical profile, and it was different from those of all other organisms in the profile index of the manufacturer. The RapID NH system is useful in the identification of C. pylori.
