Helminthiases of the Russian North

Three hundred helminthological expeditions were planned and led by the creator of Russian helminthology - academician K. I. Scrijabin in 1919-1966. In 20 of these, helminthic infections of humans, synanthropic, and wild animals in the European and the Asiatic Russian North were studied.

Opisthorchiasis (O. felineus) trichinellosis, diphyllobothriasis (D. latum) were revealed to be the principal zoonotic helminthic infections in the Russian North (Shikhobalova et al. 1969). Diphyllobothrium dendriticum was later registered in the population of the Taimir peninsula and of the North of Siberia (Klebanovskii 1980, 1985). The northern isolate of Cysticercus bovis - 'deer taeniasis' has been revealed in the indigenous population of the Yamal and the Taimir peninsulae. More than one case of E. granulosus and E. multilocularis for 100 000 of population per year are registered in the Kamchatka, Magadan, Chukotkan, Korjak regions, and in Yakutia (Bessonov 2001a,b). Anisakis simplex larvae have been found in 85.5% of 104 Siberian salmon examined, 56.7% of 231 of humpbacked salmon and in 91.2% of herring, in 89.7% in halibut, in 87.3% of Greenland halibut in the North Okchotsk Sea Region (Serdukov 1993; Vitomskova and Dovgalev 2001). The data on human anisakidosis in the northern regions of Russia are still anecdotal (Cibina and Siskova 2001).
