Imported parasitic diseases in mainland China: current status and perspectives for better control and prevention.

Background: The high prevalence of parasitic diseases leads to millions of deaths and disabilities each year in developing countries. China has also been greatly affected by parasitic infections, including filariasis, leishmaniasis, malaria, schistosomiasis, and soil-transmitted nematodosis. However, the situation in China improved dramatically after comprehensive parasitic disease control efforts were strengthened, leading to the elimination of filariasis in 2006 and to significant control over other diseases.

Snail-borne parasitic diseases: an update on global epidemiological distribution, transmission interruption and control methods.

Background: Snail-borne parasitic diseases, such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis and schistosomiasis, pose risks to human health and cause major socioeconomic problems in many tropical and sub-tropical countries. In this review we summarize the core roles of snails in the life cycles of the parasites they host, their clinical manifestations and disease distributions, as well as snail control methods.

Main Body: Snails have four roles in the life cycles of the parasites they host: as an intermediate host infected by the first-stage larvae, as the only intermediate host infected by miracidia, as the first intermediate host that ingests the parasite eggs are ingested, and as the first intermediate host penetrated by miracidia with or without the second intermediate host being an aquatic animal.

Parasitology should not be abandoned: data from outpatient parasitological testing in Guangdong, China.

Over the past six decades, the Chinese government made parasitoses with a high disease burden, including soil-transmitted nematode infections, malaria, leishmaniasis, filariasis, and schistosomiasis, a public health priority because they were seen to be crucial impediments to the development of rural areas. As a result, these debilitating parasitic diseases that used to be widely prevalent have been well controlled or eliminated. Consequently, less attention has been paid to parasitic infection during the rapid development of the economy, especially in developed areas.

History of schistosomiasis epidemiology, current status, and challenges in China: on the road to schistosomiasis elimination.

Schistosomiasis is a snail-borne disease caused by worms of the genus Schistosoma. Worldwide, human schistosomiasis remains a serious public health problem, threatening ∼800 million people in 78 countries with a loss of 70 million disability-adjusted life years. Schistosoma japonicum is the only human blood fluke that occurs in China.

Nucleic acid detection in the diagnosis and prevention of schistosomiasis.

Schistosomiasis is an important zoonotic parasitic disease that causes serious harms to humans and animals. Surveillance and diagnosis play key roles in schistosomiasis control, however, current techniques for surveillance and diagnosis of the disease have limitations. As genome data for parasites are increasing, novel techniques for detection incorporating nucleotide sequences are receiving widespread attention.

[Pathology and pathogenesis of liver fibrosis induced by Schistosoma japonicum].

Schistosomiasis is a widely distributed parasitic zoonoses that threatens human' s health and social economic development. China is one of the most endemic countries in the world. Schistosoma egg are mainly lodged in the liver and intestinal tissues.

The expression of molecule CD28 and CD38 on CD4⁺/CD8⁺ T lymphocytes in thymus and spleen elicited by Schistosoma japonicum infection in mice model.

Schistosomiasis caused by human schistosomes such as Schistosoma japonicum (S. japonicum) is considered as an immune-related disease. It was demonstrated that specific cytokine antibodies' response elicited by S.
