Gnathostoma are parasites of wild mammals and larval stages of 3 native species, G. spinigerum, G. doloresi and G. nipponicum have been found in cold blooded vertebrates. Moreover, larval G. hispidum has been found in loaches imported to Japan from east Asia (Akahane et ai, 1982). Among these species, G. spinigerum had been considered to be the only causative agent of gnathostomiasis until the ...

The geographic distribution of three Misgurnus species, M. anguillicaudatus, M. bipartitus, and M. mohoity, displays a specific pattern in China, coincident with temperature zones. In this study, we sequenced the transcriptomes of these three species and used the sequences to investigate the lineage-specific adaptations within the genus Misgurnus. In total, 51 orphan genes (19 in M. anguillicau...

Abstract We have analyzed the polymorphism of ISSR fragments DNA by polymerase chain reaction in spined loaches for first time. The analysis has made it possible to successfully differentiate genomes, which were presumably involved formation polyploid forms hybrid origin: Cobitis taenia ; from Danube River basin, are diagnosed as C. elongatoides tanaitica Don basin and Lake Sinoe, also assigned...

This study aimed to explore the gill developmental mechanism of high mortality rate Paramisgurnus dabryanus larvae in early life-history process. Based on histological observations with a optical microscope, we studied ontogeny P. dabryanus. The result indicated that external gills first appeared 12 h after hatching. number branchial filaments greatly increased at 2 d hatching (DAH). internal f...
