An overview of motile Aeromonas septicaemia management

Motile Aeromonas septicaemia is most commonly caused by Aeromonas hydrophila . It is an opportunistic pathogen causing disease in fish under stress. The bacterium produces a number of pathogenic factors, and the most important among them are the haemolysin and the aerolysin, provoking the disease. Freshwater and saltwater fish species are susceptible. The disease is manifested clinically with haemorrhages, ulcerations, abscesses, ascitic fluid and anaemia. Mortality rates are high, and they incur substantial economic losses, thereby necessitating timely measures of control for prevention and treatment. Therefore, the aim of this overview was to provide up-to-date information related to the control of motile Aeromonas septicaemia in fish through application of chemotherapeutic drugs, phytobiotics, probiotics, yeast extracts, vaccines and disinfectants.
