BackgroundMembers of the genus Aeromonas are Gram-negative bacilli, belonging to family Aeromonadaceae, and are widely found in various aquatic environments. The most common species associated with human infections are A. hydrophila, A. caviae, and A. veronii biovar sobria. Aeromonas species are recognized as emerging opportunistic pathogens in humans mainly causing gastrointestinal infections and wound infections with or without progression to septicaemia. Aeromonas organisms rarely cause urinary tract infection (UTI) and are not known uropathogens.CaseWe report a series of UTI due to Aeromonas species in three adult patients, specifically identified as A. veronii biovar sobria in two patients and A. hydrophila in one patient. Two patients had history of occupational exposure to aquatic environment.ConclusionsThe cases highlight another expanded range of infections caused by Aeromonas spp. that can be encountered in a community setting and indicate that infections with Aeromonas spp. should be kept in mind while investigating for the etiology of UTI, especially in adult patients with occupational exposure to aquatic ecosystems.Copyright © 2020 National Medical Association.
