Vibrio Albensis Bacteraemia in a Decompensated Cirrhotic Patient with an Atypical Transmission Source
Abstract
Introduction: Vibrio albensis is a rare Gram-negative halophilic bacterium belonging to the Vibrio cholerae non-O1/non-O139 (NOVC) group, which rarely causes infections in humans. To date, only approximately 5 cases of V. albensis infection in humans have been reported in the global medical literature. This bacterium is typically found in marine and brackish water environments (estuaries), with primary transmission routes including exposure to seawater through open wounds or the consumption of raw seafood.
Case description: We report a 49-year-old male with decompensated cirrhosis secondary to alcohol abuse and hepatitis C virus infection who presented with acute liver failure. On day 5 of hospitalization, the patient developed fever (39.5°C) and rigors. Two sets of blood cultures were positive for V. albensis. Notably, the patient denied any recent exposure to seawater, brackish water, or raw seafood consumption. The isolate demonstrated full susceptibility to all tested antimicrobial agents. The patient was successfully treated with ertapenem combined with levofloxacin for 7 days and discharged in stable condition after 11 days of hospitalization.
Conclusion: This is a rare case with distinctive features: (1) V. albensis bacteraemia without typical environmental exposure, (2) to the best of our knowledge the first reported case of hospital-acquired V. albensis infection, and (3) the case supports the hypothesis of opportunistic pathogenic bacteria originating from the…
