Urease-positive thermophilic Campylobacter (Campylobacter laridis variant) isolated from an appendix and from human...

Urease-positive thermophilic campylobacters were isolated for the first time from the feces of two adults with diarrheal disease and from the appendix of a child with appendicitis. They were identified as Campylobacter laridis by a hybridization dot blot assay. Urease testing should be included in the tests used for the identification of campylobacters at the species level, even for those strains which are not of gastric origin.
