Fresh insights into Aeromonas hydrophila in aquaculture

A new paper describes the complex dynamic interplay between Aeromonas hydrophila bacterium and its environment in aquaculture settings.

Fish infected with A. hydrophila can develop ulcers, tail rot, fin rot, and haemorrhagic septicaemia, which causes lesions that lead to scale shedding, haemorrhages in the gills and anal area, exophthalmia and abdominal swelling.

Published in Aquaculture International, the study, which was published under the title of "Aquaculture and Aeromonas hydrophila: a complex interplay of environmental factors and virulence", confirms the close connection of environmental conditions in shaping the prevalence and pathogenicity of A. hydrophila in aquaculture environments. Water quality, temperature, pH levels, and high ammonia concentrations exacerbate A. hydrophila infection by compromising host immunity and creating favourable conditions for bacterial proliferation. Oxygen concentration and nutrient availability complexly influence the spread and virulence of this pathogen.
