Geographical origin of aspermic Fasciola flukes, and its distribution within Japan

Hybrid origin of Asian aspermic Fasciola flukes is confirmed by analyzing two single-copy genes, pepck and pold

Nuclear gene markers, phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold), have been developed for precise discrimination of Fasciola flukes instead of internal transcribed spacer 1. In this study, these two genes of 730 Fasciola flukes from eight Asian countries were analyzed. The results were compared with their mitochondrial NADH dehydrogenase subunit 1 (nad1) lineages ...

Mesobuthus eupeus, An Indigenous scorpion from Iran. Origin and its Geographical Distribution

Molecular characterization of parthenogenic Fasciola sp. in Korea on the basis of DNA sequences of ribosomal ITS1 and mitochondrial NDI gene.

Nucleotide sequences of ribosomal internal transcribed spacer (ITS1) and mitochondrial NADH dehydrogenase I (NDI) gene were analyzed to genetically characterize aspermic Fasciola forms in Korea. From the difference in ITS1 sequences, Korean flukes were divided into 3 haplotypes represented by Kor1, Kor2 and Kor1/2, which had nucleotides identical to F. hepatica, F. gigantica and those overlappe...

Geographical distribution of leptospira-positive field rodents in Japan.

Many papers have been published on leptospira-positive rodents in selected areas of Japan. Rattus norvegicus, R. rattus, and R. rattus alexandrius trapped in urban areas and certain swamp rice fields in rural areas were found to carry L. icterohaemor-The latter two species of rodents are caught generally in the field and forest in rural areas. data), have been isolated from the rodent in Japan....
