Lymphocystis Is A Common Virus In The Fish Industry

Lymphocystis is a common virus in saltwater and freshwater fish systems. It is a member of the iridoviridae family. Fortunately, these bump do not cause serious health symptoms. They tend to be self-limiting. Lymphocysticis is caused by a group of large iridsoviruses. The skin and fins of fish develop small dark-colored nodules. The nodules are made up of infected cells. They become enlarged as the virus replicates. The cell is enlarged from 50,000 to 100,000 times the size of a normal, healthy cell. It can be confused with white spot disease because of its similar appearance. Other diseases like encysted parasites, epitheliocystitis, epistylis, digenean trematodes and others can cause these symptoms. A correct diagnosis should be made by a qualified aquatic veterinary animal prior to treatment. Lymocyst is naturally occurring in the aquatic environment. It may be passed through fish living in crowded conditions. In aquariums, it usually develops from poor water quality or stressors that may not be obvious to newer aquarium owners. Treatment can be diagnosed by taking a skin sample for microscopic evaluation. Treatment will vary based on test results. Some asymptomatic fish may have signs of the disease affecting their internal organs. L lymphocyst can be triggered by stress. To keep water conditions optimal. It's important to gently handle fish. . . .
