Helicobacter salomonis sp. nov., a Canine Gastric Helicobacter sp. Related to Helicobacter felis and Helicobacter bizzozeronii [PDF]

International Journal of Systematic Bacteriology, 1997
During a study of the prevalence and distribution of gastric helicobacters in domestic pets, a novel group of Helicobacter-like organisms were identified. These "Helicobacter group 2" strains were initially distinguished from the species Helicobacter felis and Helicobacter bizzozeronii by their cellular morphology and the type of motility exhibited ...

Misidentifying Helicobacters: the Helicobacter cinaedi Example [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACT Whole-cell protein electrophoresis and biochemical examination by means of a panel of 64 tests were used to identify 14 putative helicobacters to the species level. The results were confirmed by means of DNA-DNA hybridization experiments and were used to discuss misidentification of helicobacters based on 16S rRNA gene ...
