Among the many diseases caused by various parasites, opisthorchiasis occupies a special place. Opisthorchiasis – a disease that affects the liver and pancreas. These organs are affected as a result of infection human intestinal worms – opisthorchis. Infection occurs through a sick fish. The causative agent of this disease is a cat fluke. Most of this parasite is common in the Ob, Irtysh, Volga and Kama rivers. Excretion a sick person or animal parasite eggs get into water, ingested snails and other mollusks, multiply there and go into the water already in the form of larvae cercariae.

Cercariae introduced in cyprinids, where live up to the moment when the fish are not caught. People from eating bad fried or undercooked fish, gets live larvae into the duodenum. From there the larvae migrate to their favorite places – the bile ducts liver and pancreas. After 3-4 weeks the parasites mature and begin laying eggs. Alarming state of affairs in terms of incidence of opisthorchiasis, especially in the Tyumen region, where in 2007 only victims opisthorchiasis has more than 4000 residents of the area and still not achieved a positive clinic. Pathogens opisthorchiasis live in such delicious representatives of fish populations, like roach, chebak, ide, dace, rudd, bream, crucian carp, tench and others. And still the main cause of the disease is non-compliance with hygiene.

Let us assume, dressed fish are well treated thermally and destroyed all larvae. But if you cut the vegetables for a salad on a poorly washed fish cutting board, then the portion of the parasites you will get for sure. On this occasion, well said Tatyana Stepanova, Director of the Institute of Regional Infectious Pathology in the Tyumen region. Its meaning words is reduced to what we can determine the level of awareness of the population in terms of incidence of parasitic diseases – higher than the first, the lower the latter. Little about the symptoms of the disease opisthorchiasis. The majority of patients early stage of the disease does not manifest or observed only a slight increase in blood eosinophils. The incubation period is 2-3 weeks. The disease appears suddenly, the patient begins fever and pain in the right hypochondrium.

Main – holistic method of treatment because of chronic opisthorchiasis affected organs digestive system. Apply cholagogue, enzyme preparations, affecting the tone and motility gastrointestinal tract; diet. The most effective means for specific treatment is praziquantel.
