[Extraction and morphological observation of Oncomelania hupensis haemocytes].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2014
Haemocytes were collected from Oncomelania hupensis snails by using tissue disruption and filtration method, stained by Giemsa and methylene blue, respectively, and observed under microscope. Number of haemocytes from one snail was counted. Out of 54 haemocytes, 3 types of cells were found: big round cells with particles, small round cells with oval ...

[Seasonal changes of glycogen level in Oncomelania hupensis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2015
Oncomelania hupensis snails were collected from Qingyi River of Wuhu City from August 2012 to July 2013. Livers and pedal muscles of snails were dissected. Anthrone colorimetric method was used to evaluate the glycogen concentrations of whole-body, liver and muscle.

[Role of Oncomelania hupensis in transmission of schistosomiasis japonica].

Zhongguo xue xi chong bing fang zhi za zhi = Chinese journal of schistosomiasis control, 2013
Oncomelania hupensis is the only intermediate host of Schistosomajaponicum, and its ecological characteristics and compatibility with Schistosoma which have a great significance to the schistosomiasis control, play a very important role in the transmission of schistosomiasis.

[Spatial characteristic of distribution of Oncomelania hupensis in mountainous regions].

Zhonghua liu xing bing xue za zhi = Zhonghua liuxingbingxue zazhi, 2014
To analyze the spatial characteristic on the distribution of Oncomelania hupensis in mountainous regions.Based on the geographic database of snail distribution in Puge county, Sichuan province, spatial autocorrelation analysis and spatial scan statistics were applied to analyze the spatial characteristic of snail distribution.With regard to the rate of

[Poison effect of plant granules on Oncomelania hupensis].

Ying yong sheng tai xue bao = The journal of applied ecology, 2002
Plant granules (phi 2-3 mm) made of starch, gelatin and medicine plant powder were used to kill Oncomelania hupensis. The results showed that after eating the plant granules, the mortality of the snail was 92.5%-100% within 24 hrs. The poison effect of the plant granules was much better than that of others, e.g., they could kill snails 12-24 h earlier ...

Development of Oncomelania hupensis quadrasi embryonic cell primary culture

Parasitology International
Oncomelania hupensis quadrasi is the obligate intermediate host of Schistosoma japonicum in the Philippines and is central to sustaining environmental transmission. Although its distribution and infection dynamics have been well characterized, parasite-host interactions at the cellular level remain largely unexplored due to the lack of suitable in ...

[Research progress of control techniques on Oncomelania hupensis].

Zhongguo xue xi chong bing fang zhi za zhi = Chinese journal of schistosomiasis control, 2018
Oncomelania hupensis is the only intermediate host of Schistosoma japonicum. The elimination of Oncomelania snails is the key technique step for schistosomiasis control. This paper summarizes the progress of the techniques of snail control, including the methods of ecology engineering, biology, molluscicides and the study on novel molluscicides, and ...

[Dynamic change of population structure of Oncomelania hupensis].

Zhongguo xue xi chong bing fang zhi za zhi = Chinese journal of schistosomiasis control, 2018
Objective To understand the successive dynamic change of population structure of Oncomelania hupensis during a one-year period, so as to provide the evidence for snail control. Methods A river beach and a ditch infested with O. hupensis snails were selected and longitudinally investigated in the midmonth during one year.

[Effect of Alternanthera philoxeroides on enzymic histochemistry of Oncomelania hupensis].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2010
To investigate the mechanisms of Alternanthera philoxeroides (Mardus) Grisebach in inhibiting Oncomelania snails' locomotivity and killing effect.Uninfected snails were divided into four groups and exposed to an aqueous extract of A. philoxeroides and dechlorinated water (as control) for 12 h or 20 h, respectively.

Some aspects on the ecology and biology of Oncomelania hupensis lindoensis.

The Southeast Asian journal of tropical medicine and public health, 1977
Schistosomiasis is known to be endemic in the lake Lindu area since 1937 (Brug & Tesch, 1937). Investigations carried out later between 1940 and 1942 (Bone et al., 1942) failed to find molluscan intermediate host. It was not until April 1971 that the first specimen of Oncomelania was found (Carney et al., 1972).
