Aeromonas veronii is a
Gram-negative,
rod-shapedbacterium found in
fresh water and in association with animals.[2] In humans A. veronii can cause diseases ranging from wound infections and
diarrhea to
sepsis in
immunocompromised patients. In
leeches, this bacterium is thought to function as a
symbiote aiding in the digestion of blood, provision of nutrients, or preventing other bacteria from growing.[3] Humans treated with
medicinal leeches after
vascular surgery can be at risk for infection from A. veronii and are commonly placed on prophylactic antibiotics.[4] Most commonly ciprofloxacin is used but there have been reports of resistant strains leading to infection.[5]
Protective effect
A 2005 study showed the potential for using
probiotics for controlling Streptococcus iniae infection in
trout. This study used the gastrointestinal contents of
rainbow trout to screen for bacteria that inhibited growth of S. iniae and Lactococcus garvieae. They identified A. veronii as a potential candidate for control of S. iniae and L. garvieae infections in aquaculture. A. veronii, given live in the feed, protected the trout when challenged with S. iniae or L. garvieae.[6]
