Phlebotomine sand flies (Diptera: Psychodidae) transmitting visceral leishmaniasis and their geographical distribution in China: a review.

After the existence of phlebotomine sand flies was first reported in China in 1910, the distribution of different species and their role in the transmission of visceral leishmaniasis (VL) have been extensively studied. Up until 2008, four species have been verified as vectors of VL, namely, Phlebotomus chinensis (Ph. sichuanensis), Ph.

[Diagnostic potential of five natural antigens from Echinococcus granulosus in the patients of cystic echinococcosis with different clinical status].

Objective: To analyze the characteristics of serum antibody reactivity of cystic echinococcosis (CE) patients with different clinical status towards five native antigens obtained from Echinococcus granulosus (Eg).

Methods: The protoscolex somatic soluble antigen (EgPS), crude hydatid cyst fluid antigen (EgHF), partially purified hydatid fluid antigen (Burstein's antigen, EgBu), adult somatic soluble antigen (EgAs) and the native antigen B (EgAgB) were pre- pared. 369 serum samples from CE patients and 281 sera samples from healthy individuals were examined for the antibodies against 5 native antigens with indirect ELISA.

[Preliminary evaluation on the diagnostic performance of five native antigens from Echinococcus granulosus].

Objective: To evaluate the diagnostic potential of 5 native antigens obtained from Echinococcus granulosus.

Methods: The cyst fluid and protoscoleces were collected from infected livers of slaughtered sheep near Urumqi. The protoscolex somatic soluble antigen (EgPS), crude hydatid cyst fluid antigen (EgHF), partially purified hydatid fluid antigen (Burstein's antigen, EgBu) and the native antigen B (EgAgB) were prepared.

Genetic diversity of Leishmania donovani/infantum complex in China through microsatellite analysis.

The Leishmania strains from different epidemic areas in China were assessed for their genetic relationship. Twenty-nine strains of Leishmania infantum isolated from 1950 to 2001 were subjected to multilocus microsatellite typing (MLMT) using 14 highly polymorphic microsatellite markers. Twenty-two MLMT profiles were recognized among the 29 L.

Discovery and study of cutaneous leishmaniasis in Karamay of Xinjiang, West China.

Cutaneous leishmaniasis (CL) was discovered in the farms of the Karamay suburb, Xinjiang Uygur Autonomous Region in the 1990s. Between 1992 and 1994, a house-to-house survey revealed a prevalence of 1.0-1.

[Echinococcosis control in China: challenges and research needs].

Based on a review of the practices of echinococcosis control in China and of the historical experience from the international community in the field, this paper discussed the research achievements and challenges. The author indicated that it is a realistic time to launch a comprehensive control program in western China and there are urgent needs for scientific research integrating into the program.

Epidemiological evaluations of the efficacy of slow-released praziquantel-medicated bars for dogs in the prevention and control of cystic echinococcosis in man and animals.

To assess the epidemiological efficacy of type SRP III slow-released praziquantel-medicated bars for dogs in the prevention and control of cystic echinococcosis in man and livestock, praziquantel-medicated bars were implanted subcutaneously in over 90% of dogs in villages in north Xinjiang, China, where cystic echinococcosis is highly endemic. After implantation, infection rate of Echinococcus granulosus in dogs, specific antibodies in children and prevalence of echinococcosis in one-year-old lambs were observed for 3 years. Coproantigen of E.

[Dynamic observation on ultrasonographic image during chemotherapy of hepatic cystic echinococcosis and a proposal for ultrasonic classification].

Objective: To submit a proposal for the classification of ultrasonographic image in patients with hepatic cystic echinococcosis, on the basis of characteristic and distribution of ultrasonic image of hydatid cysts in cases and systematic observation on dynamic changes of sonographic image under treatment with emulsion albendazole and in relation to clinical efficacy.

Methods: The ultrasonic image of 645 cysts in 497 cases with liver cystic echinococcosis was classified. The distribution of different types of image in patients was analyzed.
