Bacteremia Caused by Aeromonas hydrophila Complex in the Caribbean Islands of Martinique and Guadeloupe

Aeromonas species are Gram-negative bacilli of the water environment whose survival appears facilitated by warm climates. There have been no reports on Aeromonas hydrophila complex ( A. hydrophila , A. caviae , A. veronii ) in the Caribbean to date. Our aim was to describe clinical and bacteriological features in patients presenting with such bacteremia in Martinique and Guadeloupe. During a 14-year period, we retrospectively identified 37 patients. The mean age was 55 years and in 89% of cases underlying disease such as digestive diseases, cutaneous wounds, and malignancy were identified. One case was related to severe strongyloidiasis and one with snake bite. Polymicrobial bacteremia was identified in 38%, essentially with Enterobacteriaceae . All Aeromonas isolates were resistant to amoxicillin but extended-spectrum beta-lactam and fluoroquinolone were active against more than 95%. During hospitalization 10 patients died (27%). Older age, occurrence of multiorgan failure, and impaired renal function were associated with in-hospital mortality.
