Papillomatosis is a poorly studied viral disease with a chronic course. In appearance resembles warts on the legs. The disease was first discovered in the fifties of the XX century in natural populations and on fish farms. Papillomatosis is a benign tumor of connective tissue, covered on top of keratinized skin. It occurs due to viruses that affect DNA cells, causing their deformation. The source of infection is always a sick fish, which is kept together with healthy individuals, or if the fish have the same care equipment. The incubation period of the virus is 2-3 weeks from the time of infection. The diagnosis is established by histological examination and observation of the clinical picture of the disease. Most often, labyrinth species of fish are susceptible to the disease, such as pineapples, gourami, laliuses, striped colises.
Symptoms of the disease
The disease can be suspected by the presence of tumor-like growths of white-gray color on the fins, in the area of the oral opening, near the gill covers or in other places. Papillomas grow slowly in the form of villi, warts or flat tumors. They spread along the free surface, when located on the mucous organs, can disrupt its function. The size, quantity and external state of tumors in different individuals manifests itself in its own way. In size, tumors can range from one to five millimeters, and can appear both simultaneously and one after another. They look like millet or lentil grain.
There is no specific treatment for papillomas (papillary tumors). Often, self-healing of infected tissue occurs. Sometimes during treatment they use surgical intervention or cauterization of places with hot metal papillomas. The disease is not fatal, that is, the fish do not die. However, for prevention, in order to avoid the spread of the disease among other inhabitants of the aquarium, sick fish are removed from there, and the aquarium itself is subjected to thorough disinfection.
