| [the role of the owsianka leucaspius delineatus in maintaining opisthorchiasis foci in novosibirsk province]. | 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 itself in natural water bodies, inaccessible for predatory animals, easily infected with opisthorchis larvae, and therefore can play an impor ... | 1989 | 2628714 |
| [the outer membranes of the eggs of opisthorchis felineus and clonorchis sinensis]. | the outer coats of opisthorchis felineus and clonorchis sinensis eggs have been examined by scanning electron microscopy. the outer coat turned to be extremely sculptured, presenting as interlaced crests of various height. the authors suggested the possibility of using this indicator in the taxonomy of opisthorchiidae and studying their distribution in biocenoses as well as their ability of accumulating on the leaves of aquatic plants, thus facilitating the contact with their intermediate hosts ... | 1989 | 2693924 |

| intestinal helminths of cats in the kainji lake area, nigeria. | six parasitic helminths detected were ancylostoma sp., opisthorchis felineus, toxocara mystrax, hepaticola hepatica, taenia sp. and hydatigera taeniaeformis. the prevalence of h. hepatica, t. mystrax and h. taeniaeformis is associated with rodents hunted by cats, and that of o. felineus with fish fed to cats. the role of cats as primary host and reservoir for these helminths, which could be of zoonotic importance, is briefly mentioned. | 1986 | 3716201 |
