New Oncomelania hupensis Foci on Taiwan

The Journal of Parasitology, 1976
Six new areas for Oncomelania hupensis were found on Taiwan: three in Nan-tou, and 1 each in Chia-i, Hua-lien and Tai-tung counties. Most of the new habitats, unlike previously known areas, are not in alluvial plains, but are at higher elevations. The Nan-shan-chi colony in Nan-tou county is located at the altitude of 740 m, which is the highest of all

Intestinal microbiome profiles in Oncomelania hupensis in mainland China

Acta Tropica, 2020
Oncomelania hupensis plays a significant role in the transmission of schistosomiasis japonica, which remains a major public health concern in China. Understanding the biological characteristics of O. hupensis is a prerequisite for its control; however, there are currently no studies investigating the intestinal microbiota of the O. hupensis snail. This

Transplantation of Schistosoma japonicum Daughter Sporocysts in Oncomelania hupensis

The Journal of Parasitology, 1985
Schistosoma japonicum daughter sporocysts obtained from infected Oncomelania hupensis hupensis were successfully transplanted to parasite-free O. hupensis hupensis. Survival and infection rates of recipient snails were 80% and 75% respectively. Intramolluscan development of transplanted daughter sporocysts in recipient snails appears to proceed in a ...

Molluscicidal activity against Oncomelania hupensis of Ginkgo biloba

Fitoterapia, 2008
In search for molluscicidal active components, petroleum ether, ethyl acetate, ethanol, and water extracts from Ginkgo sarcotesta were evaluated against the snail Oncomelania hupensis. The bioassay-oriented showed that the activity concentrates in the petroleum ether extract (LD(50) 7.81 ppm). Ginkgolic acids, isolated from the petroleum ether extract,

Effect of temperature on the development of Schistosoma japonicum within Oncomelania hupensis, and hibernation of O. hupensis

Parasitology Research, 2006
The objectives of this investigation were to assess the effect of temperature on the development of Schistosoma japonicum harboured in Oncomelania hupensis and to determine the lowest temperature threshold at which the hibernation of O. hupensis occurs. In the first experiment, adult infection-free O.

[Observation on eggs of Oncomelania hupensis hupensis with scanning electron microscope].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2003
To observe the structure of the mud hull packed Oncomelania eggs and the surface structure of colloid membrane called the third grade membrane of eggs.Scanning electron microscopy was used to observe Oncomelania snail eggs with integral mud hull collected from eastern Dongting Lake.The mud hull of eggs was made of unshapen small humification combined ...
