Biochemical differentiation in bile duct cestodes and their marsupial hosts.
Isozyme electrophoresis was used to assess possible cospeciation of parasites (cestodes of the Progamotaenia festiva complex) and their hosts (Australian diprotodont marsupials) and to compare the extent of interspecific genetic diversity of the parasites and their hosts. On the basis of morphology, there are three species in the complex, although electrophoresis revealed 14 distinct genetic ty...
متن کاملCestodes of cestodes of Peruvian freshwater stingrays.
Adult tetraphyllidean tapeworms (Platyhelminthes: Eucestoda) from the spiral intestines of 3 species of potamotrygonid stingrays (Paratrygon aiereba, Potamotrygon castexi, and Portamotrygon motoro) in the Madre de Dios river in Peru were found to host numerous cysts embedded in their parenchymal tissues. Histological sections of the cysts revealed the presence of a scolex bearing 4 suckers and ...
متن کاملThe development of nonradioactive total genomic probes for strain and egg differentiation in taeniid cestodes.
Purified total genomic DNA labeled with photobiotin was used as a probe for the identification and differentiation of strains of Echinococcus granulosus and to distinguish between the morphologically identical eggs of 2 taeniid species. Such biotinylated probes are easily prepared and can be utilized effectively for rapid screening and identification of taeniid isolates by dot and Southern blot...
متن کاملIn vitro differentiation of sperm from male germline stem cell.
In this study, we developed a model of sperm in vitro differentiation to study the mechanism of spermatogenesis. We isolated newborn male germ cells for in vitro differentiation. We found that after 4-5 weeks of culture, sperm-like cells were occasionally observed in cell co-culture and the feed-layer. After 1-2 weeks of culture followed by 4-5 weeks of co-culture, sperm-like cells were observed.
متن کاملFauna of British India. Cestodes. Vol. I
After a full discussion of the many attempts that have been made in recent years to formulate a working classification of the Cestoda, the author of this book suggests still another. He divides the Class into tw? Orders, Cestodaria and Eucestoda, which has the merit of simplicity and consistency, in that it makes a clear division between the Monozootic and Polyzootic cestodes, and which consequ...
