Abstract/Description: | Enterocytozoon cytopenaei (EHP) belongs to a group of microbes called microsporidia classified as fungus, and was first reported in tiger shrimp in 2009 in Thailand. There are no specific signs and symptoms in shrimp due to EHP infection. However, EHP has been reported to be associated with growth retardation and white faeces syndrome (WFS) in shrimp (needs to be proved). The target organ of EHP is hepatopancreas and affects its digestive and absorptive functioning resulting in poor growth and immunity. EHP can be detected microscopically and by polymerase chain reaction technique. There is no drug for the control of EHP infection in shrimp. SPF broodstock, live feed such as polychaete worms, clams, oysters, Artemia and other inputs have to be screened and ensured free from EHP. The EHP spores in fecal pellets or dried cadavers can remain viable up to six months and retain infectivity for over a year under aqueous conditions. Application of lime and maintaining the soil pH to 12 has been suggested for the disinfection of ponds. Better management practices (BMPs) and proper biosecurity is the only way to keep this parasite away from the aquaculture ecosystem. |
