an uncommon helicobacter isolate from blood: evidence of a group of helicobacter spp. pathogenic in aids unusual helicobacter sp. was isolated from the blood of a human immunodeficiency virus (hiv)-infected patient. this organism had spiral morphology, with single amphitrichous flagella, and was negative for hippurate hydrolysis, production of urease, and reduction of nitrate. 16s rrna gene sequence analysis verified that the isolate was a species of helicobacter, most closely related to an undescribed helicobacter-like isolate from vancouver, british columbia, canada, and to helicobacter westme ...199910405434
the rapid detection of low molecular mass proteins differentially expressed under biological stress for four helicobacter spp. using proteinchip technology.helicobacter pylori is one of the most prevalent human pathogens in the world and is the aetiological agent of gastritis, peptic ulcer disease and gastric malignancies. in addition h. pylori and other novel members of the genus are capable of successfully colonising the bile-rich niche of the upper intestine and are associated with a diverse range of intestinal pathologies. surface-enhanced laser desorption/ionisation-time of flight mass spectrometry was used to analyse surface extracts from h. ...200312627380
