Helicobacter is a gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces and blood of homosexual men, and can cause bacteremia in immunocompromised patients.
The organism was identified at the University of Colorado Hospital Clinical Laboratory in the microbiology department.
