Morphological and molecular characterization of invasive Biomphalaria straminea in southern China.

Background: Schistosomiasis is a common parasitic disease designated as a neglected tropical disease by the World Health Organization. Schistosomiasis mansoni is a form of the disease that is caused by the digenean trematode Schistosoma mansoni, transmitted through Biomphalaria spp. as an intermediate host.

Predicting the spatial distribution of Biomphalaria straminea, a potential intermediate host for Schistosoma mansoni, in China.

Schistosomiasis is one of the most prevalent parasitic diseases impacting human health in the tropics and sub-tropics. The geographic distribution of Schistosoma mansoni, the most widespread species, includes areas in Africa, the Middle East, South America and the Caribbean. Snails of the genus Biomphalaria act as intermediate host for S.

[Species identification of freshwater snail Planorbella trivolvis and analysis of its potential distribution].

Objective: To identify the species classification of an ornamental Planorbidae from a flower market in Shanghai and analyze its potential distribution in China.

Methods: In August 2013, six freshwater snail specimens were collected from the Wanshang flower market. The species was identified by morphology and molecular biology.

[Species composition and distribution of medical mollusca in Shanghai City].

Objective: To investigate the species diversity and distribution of medical mollusca in Shanghai City.

Methods: From August 2012 to October 2013, all kinds of habitats in 8 districts and counties in Shanghai City, namely Jiading, Qingpu, Baoshan, Minhang, Songjiang, Jinshan, Chongming, Pudong, were selected for the field survey according to the distribution characteristics of the river system, and all the specimens of medical mollusca in the investigation sites were collected and classified by morphological identification. Meanwhile, the species composition, habitats as well as the fauna of the medical mollusca collected were analyzed.

[Investigation on the species distribution and infection status of host snails of Angiostrongylus cantonensis in Shanghai].

Objective: To investigate the species distribution and infection status of host snails of Angiostongylus cantonensis in Shanghai.

Methods: From August 2012 to October 2014, 10 districts or counties were selected for this investigation in Shanghai, including Jiading, Qingpu, Putuo, Baoshan, Yangpu, Minhang, Songjiang, Jinshan, Chongming, and Pudong. All of the snails were examined by lung-microscopy and tissue homogenate methods.

[Comparative analysis of mitochondrial genomes of Angiostrongylus cantonensis].

Objective: To compare the diversity of mitochondrial genomes of Angiostrongylus cantonensis in the mainland of China.

Methods: According to the population genetic of A. cantonensis, seven female worms were selected to characterize the mitochondrial (MT) genomes.
