Introduction
Aeromonas species are motile Gram negative rods of the family Aeromonadaceae. They are emerging human pathogens suspected to cause gastroenteritis ranging from mild enteritis to cholera-like diarrhoea. Aeromonas species have also been reported to cause infections such as septicaemia, endocarditis, osteomyelitis, myonecrosis, haemolytic uraemic syndrome, meningitis, peritonitis, respiratory tract disease and ocular infections. In addition to humans, they are also important pathogens in amphibians, reptiles and fish, causing major problems in fish farming. Aeromonas species have also been isolated from a variety of foods such as vegetables, raw milk, ice cream, meat and seafood. Quorum sensing in Aeromonas has been shown to control both the production of extracellular proteases and biofilm formation.
