[PATHOGENS OF HUMAN TREMATODIASES IN THE PRIMORYE TERRITORY].

The Primorye Territory of Russia is part of a natural habitat for pathogens of four human trematodiases: metagonimiasis (caused by the two worms Metagonimus yokogawai and M. katsuradai in the region), nanophyetiasis (Nanophyetus salmincola schikhobalowi), paragonimiasis (Paragonimus westermani ishunensis), and clonorchiasis (Clonorchis sinensis). The tensest situation in the region has emerged with clonorchiasis, the pathogen of which is extending its area due to anthropogenic sources. In addition to the above mentioned trematodes, the investigators have found 18 more species that may inhabit human beings.
