Aeromonas hydrophila, one reason causing the death of freshwater crayfish Procambarus clarkii (Girard, ۱۸۵۲)

Procambarus clarkii crayfish has been developed as an excellent animal model to study the characteristics and pathogenesis of white spot syndrome virus and the host defense mechanisms of crustacean. However, due to pathogen infections of crayfish in Chinese farms, research based on this model has been slowed down. Using triplex polymerase chain reaction, we found the virulence Aeromonas hydrophila was one reason that caused the death of crayfish. The isolated AH-۳ produced ۱۰۰% mortalities with ۳-۲۴h after inoculation of ۱×۱۰۶ colony-forming units of live cells per crayfish at ۲۰ ˚C.
