Virulence factors of aeromonads--an emerging food borne pathogen problem.

Aeromonas spp. possess a number of virulence properties which are considered responsible for intestinal and extra-intestinal infections in human beings and also for a wide variety of infections in animals. The paper discusses current status of colonization and toxic factors of Aeromonas spp., especially in relation to food and biochemical markers. Future research needs are also identified.
