TOMSK, Jul 11 - RIA Tomsk. Scientists of Tomsk State Universityiversity (TSU) and Siberian State Medical University (SSMU) are studying the distribution of opisthorchiasis in Siberia and on the results of research will form a model which will help predict extent and ways of infection; scientists from Switzerland will join the study, the press service of TSU reported on Thursday.

It is specified that the Tomsk region - is one of the main centers of opisthorchiasis in Eurasia. This is due to the high contamination of fish in the rivers of the Ob-Irtysh basin. Fish is traditionally included in the diet of Siberians, hence the infection of the population. According to statistics, over a thousand new cases of the disease are registered in the Tomsk region every year, more than a quarter of which are - in children.

"The objects of the comprehensive study will be people; mollusks - as intermediate hosts; fish from the carp family - as the main source of infection; wild and domestic animals. Data on all links in the chain through which the causative agent of a dangerous parasitic disease is transmitted will help regulate the situation - to develop preventive measures for protection of the population from the traditional Siberian disease", - is said in the statement.

It is added that colleagues from Swiss Tropical and Public Health Institute (a subsidiary of University of Basel), with which Siberian State Medical University cooperates, will help Tomsk scientists to trace the entire chain of transmission of the causative agent. Earlier, the Swiss have studied the incidence of opisthorchiasis among residents of Thailand, Laos and other southeastern countries.

"The data obtained by biologists and physicians during the joint research will be the basis for the information model. It will allow, firstly, to predict the scale and ways of spreading invasion, secondly, to develop preventive measures that will help protect the population from a parasitic disease", - reports the press service.

According to the press service, the discovery of the causative agent of opisthorchiasis - the cat fluke (flat helminth from 10 to 12 millimeters long) - belongs to the professor of the Imperial Tomsk University Konstantin Vinogradov: in 1891 conducting a pathological autopsy, the scientist for the first time in history found a fluke in a liver of a man, extracted it and made a description.
