Distribution and species composition of potato viruses in the Novosibirsk region.

Among the many diseases that affect potato plants, viral infections are the most common and cause significant damage to farms, affecting both the yield and quality of potatoes. In this regard, an important condition for preserving the potato seed fund in Russia is systematic monitoring and early highly specific detection of potato viral infections. The purpose of the work is to study samples of potato varieties collected in the Novosibirsk region for the presence of viral infections using RT-PCR.

Microsatellite markers for Opisthorchis felineus to understand its genetic diversity and transmission patterns of opisthorchiosis.

Opisthorchis felineus is a food-borne trematode which causes opisthorchiosis and affects mainly the liver and bile ducts of the liver with a possible risk of bile duct carcinogenesis resulting in cholangiocarcinoma. In Russia, O. felineus is mainly endemic in Western Siberia (Ob and Irtysh river basins) and occurs throughout the Volga, Kama, Don, and Dnepr river basins.

Molecular genetic species definition of Opisthorchiidae-like cercariae from Bithyniidae snails of Chany Lake (South-Western Siberia, Russia).

The studies of opisthorchiids larval stages associated with Bithyniidae snails can provide important and the most reliable data for opisthorchiidoses foci characterization due to the low mobility of such opisthorchiid's host species as Bithyniidae snails. The foci of opisthorchiosis (caused by Opisthorchis felineus) and metorchiosis (caused by Metorchis bilis) are overlapping in the basins of the Ob and Irtysh Rivers. Thus, difficulties with determining the species of cercariae significantly reduce the accuracy of epidemiological conclusions regarding opisthorchiosis, which has a much higher medical significance.

Behavioral effects and inflammatory markers in the brain and periphery after repeated social defeat stress burdened by Opisthorchis felineus infection in mice.

The combination of 4-week repeated social defeat stress (RSDS) and Opisthorchis felineus infection was modeled in C57BL/6 mice. Various parameters were compared between three experimental groups of male mice (SS: mice subjected to RSDS, OF: mice infected with O. felineus, and OF + SS: mice subjected to both adverse factors) and behavior-tested and intact (INT) controls.

The role of non-commercial cyprinids in maintenance and spread of the opisthorchiasis focus in the middle Ob River basin (Tomsk region, Russia).

The study assessed the role of non-commercial cyprinid species in maintaining the opisthorchiasis focus in the middle Ob River basin, Tomsk region, Russia. The source of infection for humans and carnivores is fish of the family Cyprinidae. This is the most numerous family, 14 species live in the middle Ob River basin, which includes 6 commercial species and 8 non-commercial species.
