Aeromonas caviaeRANK: Species
TAXONOMY: Bacteria -> Proteobacteria -> Gammaproteobacteria -> Aeromonadales -> Aeromonadaceae -> Aeromonas -> Aeromonas caviae
Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped bacteria that morphologically resembles members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ubiquitous in fresh and brackish water. Two major diseases associated with Aeromonas are gastroenteritis and wound infections, with or without bacteremia. Gastroenteritis typically occurs after the ingestion of contaminated water or food, whereas wound infections result from exposure to contaminated water. In its most severe form, Aeromonas spp. can cause necrotizing fasciitis, which is life threatening, usually requiring treatment with antibiotics and even amputation.
This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
