Abstract : During past one year the following results were obtained: (1) As the host of P. miyazakii, a small snail, Bythinella nipponica akiyoshiensis was first determined by experiments. In addition, this snail was proved to be less susceptible to P. ohirai and non-susceptible to P. westermani. (2) The brown rat, Rattus norvegicus and the wild boar, Sus scrofa leucomystax were revealed to be the final host of P. miyazakii. (3) P. sadoensis was found as a new lung fluke on Sado Island, Niigata prefecture, which was proved to be able to mature in the albino rat, Rattus norvegicus, R. rattus, Mus molossinus and the dog. (4) Tricula minima was decided as the snail host of P. sadoensis. Its cercaria was first studied under the scanning electron microscope. (5) In Thailand, P. harinasutai was discovered as a new lung fluke, the metacercaria of which was abundantly parasitic in a crab, Potamon smithianus. Its egg was similar to that of P. westermani in morphology. (6) In Malaysia, two kinds of crab, Parathelphusa maculata and Potamicus cognatus were added to the list of the crab host for P. westermani. (7) In Indonesia, India and USSR, the existence of P. westermani was re-confirmed. (8) In Mexico, two species of Paragonimus were recognized, and one was most probably a new species and the other was similar to the new fluke found in Colombia. (Author)
