ABSTRACT
OBJECTIVES: Aeromonas species is a gram-negative, facultative anaerobe of the family Vibrionaceae. The organism has been recognized as a pathogen associated with illness in human, such as acute gastroenteritis, cellulitis, septicemia, and other rare diseases. METHODS: To evaluate the clinical significance of Aeromonas bacteremia in Korea and it's susceptibility of antibiotics, we evaluated the 17patients with Aeromonas bacteremia. Identification was done by use of API 20E system and antibiotic susceptibility was tested with disk diffusion method. RESULTS: Male to female ratio was 11:6, and mean age was 54.1years(8-85years) old. Liver cirrhosis was the most common underlying disease(10cases of 17patients, 58.8%a). Other underlying diseases were as follows: gallstone in 2cases, cholangiocarcinoma in 2cases, and aplastic anemia in 1case, cerebral infarction in 1case. But one had no underlying disease. So Aeromonas bacteremia were occurred in 14immunocompromised patients(82.3%), and in 10patients with hepatobiliary diseases, A. hydrophila was most commonly isolated(13cases, 764%), and the A sobria(4cases, 23.5%) was infrequently isolated. The overall fatality was 47%, and there had no significant difference in fatality between A. hydrophila and A sobria All Aeromonas species had resistance to ampicillin and carbenicillin. CONCLUSION: Because Aeromonas bacteremia may occur through water-borne route, especially in immunocompromised host. We should pay attention to immunocompromised patients, espacially having hepatobiliary disease.
