Natural foci of opistorchiasis were studied in southern West Siberia. It has been shown that the foci are of two biocenotic groups: floodplain-river and lake-interfluve. The main difference between them is that in the former intermediate hosts of opistorchides are commercial Cyprinidae fish and final hosts are humans and domestic carnivores, whereas in the(More)
In Russia, both alveolar and cystic echinococcoses are endemic. This study aimed to identify the aetiological agents of the diseases and to investigate the distribution of each Echinococcus species in Russia. A total of 75 Echinococcus specimens were collected from 14 host species from 2010 to 2012. Based on the mitochondrial DNA sequences, they were(More)
The paper analyzes data of the long-term monitoring of Hepaticola hepatica (Bancroft, 1893) Hall, 1916 prevalence in rodents in subtaiga small-leaf forests of the Northern Baraba lowland (the Severnyi raion of Novosibirsk oblast). The study found that the prevalence was (10.4 ± 1.02)% in Arvicola terrestris L., 1758; 4.5% in Microtus agrestis L., 1761; 3.4%(More)
The paper presents an analysis of the incidence of cerebrovascular diseases (CeVD) in the cohort of Russian workers involved in recovery tasks after the Chernobyl accident. The studied cohort consists of 53,772 recovery operation workers (liquidators) who arrived in the zone of the Chernobyl accident within the first year after this accident (26 April(More)
Materials reflecting opisthorchiasis infection in fish in the Novosibirsk region were analyzed. On the basis of fish population estimation and studies on its invasion with Opisthorchis felineus (Rivolta, 1884) it was shown that a considerable part in maintaining opisthorchiasis foci is played by Leucaspius delineatus. It is numerous, can easily acclimatize(More)
The water shrew population was studied in Ust-Urgulca (Novosibirsk Province) in 1978-1990; abundance, sex and age structure, reproduction rate of this animal and its helminth fauna were examined. It was found that the abiotic factors (in particular the water level of habitat areas) influenced on the water shrew populations. The number of water shrews(More)
A new genus Brachylepis gen. n. hymenolepididean cestodes associated with common shrews (Sorex) in Siberia and Russian Far East is created. These genus includes three species removed from the genus Mathevolepis: Brachylepis morosovi (Karpenko, 1994) comb. n. (type species), B. sorextscherskii (Morosov, 1957) comb. n. and B. triovaria Karpenko, 1990) comb.(More)
The redescription of the cestoda Hepatocestus hepaticus (Baer, 1932) was made on the original material from the Western Siberia shrews in connection with the first registration this species at shrews within the east palearctic. The analysis of the morphology of the H. hepaticus from the western Siberian populations of shrews hadn't reveal essential(More)
This paper continues a series of publications that analyze the impact of radiation on incidence of circulatory system diseases in the cohort of Russian recovery operation workers (liquidators) and presents the results of the analysis of cardiovascular disease (CVD) incidence. The studied cohort consists of 53,772 liquidators who arrived in the Chernobyl(More)
