A Impact of Aeromonas veronii Infection in Freshwater Fishes and Its Threat to Mankind: A Review

Abstract

The emerging pathogen Aeromonas veronii is extensively dispersed and can infect fishes, humans and animals. It is a broadly distributed gram-negative, facultatively anaerobic bacterium. It causes Epizootic Ulcerative Syndrome (EUS) and fish sepsis in several freshwater fishes such as tilapia, catfish, carp, and loach etc. The high mortality rates among commercial fish species leads to huge financial losses to the aquaculture sector. Antibiotics were once a successful preventative measure in this regard. However, the widespread use of antibiotics in recent years has resulted in antibiotic resistance. Probiotics, vaccines, and phytochemicals are some of the control measures that can be used in place of antibiotics. The present review will provide information about overview of A. veronii infection in fishes, its effect on both human and animal wellbeing, virulence, and its management approaches in aquaculture.
