| genetic variability and differentiation of natural populations in three japanese lung flukes, paragonimus ohirai, paragonimus iloktsuenensis and paragonimus sadoensis (digenea: troglotrematidae). | the genetic differences among 3 closely related species, paragonimus ohirai, paragonimus iloktsuenensis and paragonimus sadoensis, were assessed by electrophoretic analysis of allozymes. fifteen enzymes were analyzed using starch gel electrophoresis. seven of 18 loci were polymorphic. the most variable population (pos) was polymorphic at 6 of the loci (p = 0.333) with a heterozygosity h of 0.054. genetic distances between p. ohirai and p. iloktsuenensis, between p. ohirai and p. sadoensis, and b ... | 1986 | 3746563 |
| evidence for metacercarial polymorphism in lung flukes, paragonimus ohirai and paragonimus iloktsuenensis. | cross breeding experiments between 2 species of lung fluke, paragonimus ohirai and paragonimus iloktsuenensis, were carried out using metacercarial characteristics as distinguishing markers. all metacercariae of f1 obtained were identical to those of p. ohirai. in the f2 and bf1 of f1 x p. iloktsuenensis, both the p. ohirai and p. iloktsuenensis types of metacercariae appeared. in the bf1 of f1 x p. ohirai, however, only the p. ohirai type metacercariae were produced. no intermediate type betwee ... | 1985 | 4093814 |
