[Genetic differentiation of helminths on the basis of data of polymerase chain reaction using random primers]

The genetic variability of helminths belonging to the three classes Cestoda, Nematoda and Trematoda was analysed by means of polymerase chain reaction with randomly amplified polymorphic DNA (RAPD-PCR). Dendrograms of genetic relationships between some representatives of the genus Trichinella, Fasciola hepatica, Cysticerus ovis, Echinococcus granulosus, and Nematodirus spathiger were constructed on the basis of DNA amplification patterns. The formation of ecological and genetic adaptations in the helminth groups studied is discussed.
