Variability within NADH dehydrogenase sequences of Echinococcus multilocularis

The paper describes the variability of the NADH dehydrogenase sequences of Echinococcus multilocularis from 4 fox isolates in Poland, in comparison wi th the previously described genetic variants of this species. Polish isolat e was more similar to the isolate from japan than to the genetic variants M 1 and M2, both of which are found in Europe. The level of variability obser ved within ND1 sequences off, multilocularis, is comparable with the variab ility reported for some pairs of most similar strains of E. granulosus (G1/ G2, G2/G3, G1/G3, G6/G7).
