| Abstract |
We report a case of infected abdominal aortic aneurysm caused by "Helicobacter rappini". A female in her 80s who had fever, anorexia, abdominal pain, and left lower back pain was admitted to the hospital because of suspicion for infected abdominal aortic aneurysm by computed tomography scans. Blood cultures obtained on hospital admission grew spiral-shaped, gram-negative bacteria. Helicobacter species was suspected due to its shape and biochemical characteristics. She received antimicrobial therapy, underwent artificial blood vessel replacement, and discharged without any recurrence for at least one year. We identified "H. rappini" by 16s rRNA genetic analysis of the bacteria isolated from blood cultures and the infected tissue. This species has not been formerly accepted and its clinical presentation is rarely known. |
