Aeromonas are gram-negative bacteria that grow in freshwater and marine environments and can cause wound infections ranging from mild cellulitis to necrotizing fasciitis. Aeromonas strains may be resistant to antibiotics commonly used to treat SSTIs caused by other bacteria. In addition, Aeromonas infections have been associated with gastroenteritis, sepsis, and involvement of multiple extraintestinal sites.
