Schistosomiasis remains a serious public health issue in many tropical countries, with more than 700 million people at risk of infection. In China, a national integrated control strategy, aiming at blocking its transmission, has been carried out throughout endemic areas since 2005. A longitudinal study was conducted to determine the effects of different intervention measures on the transmission...

Despite decades of prevention and control efforts, the water-borne parasitic disease schistosomiasis remains endemic in 74 of the world’s developing nations. Five species of the Schistosoma trematode are pathogenic to humans; S. japonicum is the infective agent of schistosomiasis in China and the Philippines. The purpose of this research is to develop a sensitive and specific technique for the ...

Sodium pentachlorophenate (NaPCP) is still one of the most commonly used molluscicides in Japan ; since 1953, the major endemic areas of schistosomiasis have been treated with this compound twice a year, in spring and autumn when irrigation is stopped. It is therefore of interest to know whether resistance of the snail to the molluscicide appears in the areas. Some authors (Okabe, Okahara and O...

Schistosomiasis is a parasitic disease mostly found in areas along the Changjiang River, Oncomelanias is the only intermediate host of schistosomiasis. Oncomelania entering into farmland or the residential zones through the flood discharge or irrigation system is the main reason of spreading schistosomiasis. Therefore it is most essential and effective way to control diffusion of oncomelanias a...

Up to the present, the experimental infection with Paragonimus ohirai larvae in the gastropod molluscus belonging to 5 genera including 10 species has been carried out by the author and some other workers. The results showed that this fluke has a high infectivity to amphibious molluscs such as Assintinea parasitologica, A. yoshidayukioi, Paludinella japonica and Oncomelania nosophora rather tha...
