Spatial analysis of visceral leishmaniasis in the oases of the plains of Kashi Prefecture, Xinjiang Uygur Autonomous Region, China.

Background: Kashi Prefecture of Xinjiang is one of the most seriously affected areas with anthroponotic visceral leishmaniasis in China. A better understanding of space distribution features in this area was needed to guide strategies to eliminate visceral leishmaniasis from highly endemic areas. We performed a spatial analysis using the data collected in Bosh Klum Township in Xinjiang China.

West nile virus infection in Xinjiang, China.

An outbreak of fever and meningitis/encephalitis occurred in Xinjiang, China, from August 5 to September 3, 2004. In preliminary diagnostic testing, several cerebrospinal fluid (CSF) and serum samples showed positive immunoglobulin M (IgM) antibody to Japanese encephalitis virus. Here, the CSF and serum samples of 6 cases collected at that time were tested by immunofluorescence assay (IFA), enzyme-linked immunosorbent assay (ELISA), and plaque reduction neutralization assay (PRNT) for the existence of IgM antibody or neutralization antibody against West Nile virus (WNV) or other arboviruses.

Isolates of Liao ning virus from wild-caught mosquitoes in the Xinjiang province of China in 2005.

Liao ning virus (LNV) is related to Banna virus, a known human-pathogen present in south-east Asia. Both viruses belong to the genus Seadornavirus, family Reoviridae. LNV causes lethal haemorrhage in experimentally infected mice.

[Biological and phylogenetic analysis of first isolate of Tahyna virus in China].

In 2006, the first Chinese Tahyna virus isolate (XJ0625) was obtained in Xinjiang province and human infection were found in the same region. In this study, cell culture, animal experiments, electron microscopy, immunofluorescence assay and cross neutralization tests were performed to see the cell susceptibility, animal pathogenicity, morphology and antigenic and other biological characteristics of XJ0625. In addition, molecular biology software was used to analyze the characteristics of molecular evolution.

An outbreak of the desert sub-type of zoonotic visceral leishmaniasis in Jiashi, Xinjiang Uygur Autonomous Region, People's Republic of China.

Few outbreaks of the desert sub-type of zoonotic visceral leishmaniasis (VL) have been described worldwide. In 2008, the incidence rate of VL in Jiashi County, Xinjiang Uygur Autonomous Region in the western part of the People's Republic of China, increased more than twenty-folds compared to the average annual incidence rate. The majority of the cases (96.

[An epidemiological survey of visceral leishmaniasis in Hamangou coal mine area of Korla City, Xinjiang].

Objective: To investigate the epidemiological status of visceral leishmaniasis in Hamangou coal mine area of Korla City of Xinjiang Uygur Autonomous Region.

Methods: Based on a hint of possible existence of patients, a retrospective survey was carried out house by house to find cases with suspected signs/symptoms of the disease. Meanwhile, a survey on current status was conducted, including physical examination (liver and spleen palpation) to those less than 15 years-old, leishmanin skin test and rk39 immunochromatographic strip test for part of the residents.

[Study on time-space clustering regarding the distribution of visceral leishmaniasis in Kashgar Region, Xinjiang].

Objective: To probe time-space clustering on the distribution of visceral leishmaniasis (VL) in Kashgar Region.

Methods: Based on the geographic information system, a Poisson model of time-space statistical software was applied to analyze data over the past 11 years in the Kashgar Region. Zones with clustering phenomenon were conformed by geographic location and remote sensing images.

[Isolation and primary identification of viruses in mosquitoes in the south of Xinjiang].

Objective: To isolate viruses from mosquitoes in the south of Xinjiang and identify these viruses primarily.

Methods: A total of 13 491 mosquitoes were collected in the south of Xinjiang from Jul to Aug, 2005. These mosquitoes were divided into 130 groups and grinded respectively.

[A new member of Brevidensovirus, 0507JS11 virus isolated from Culex mosquitoes collected in Xinjiang].

Objective: To probe the primary characteristic of 0507JS11 virus isolated from Culex sp. and determine the classification of 0507JS11 virus in taxonomy.

Methods: 0507JS11 virus was cultured in Aedes albopictus C6/36 cells and cytopathic effects (CPEs) were recorded.

[Investigation on echinococcosis in animals in Gannan Tibetan Autonomous Prefecture].

Objective: To make an investigation on echinococcosis among animals in Gannan Tibetan Autonomous Prefecture.

Methods: 21 villages from Maqu and Luqu counties were selected for the survey in August of 2004-September of 2007. Rodents were trapped in the field.

[0507JS60 virus isolated in Xinjiang was identified as Liaoning virus].

0507JS60 virus was isolated from a pool of Culex sp. collected in Kashi, Xinjiang, which could be propagated stably on C6/36 cells and caused cytopathic effects continuously. Viral particles had no envelope and appeared round with diameter of about 55nm (n = 10).

[New type of cytoplasmic polyhedrosis virus isolated from mosquitoes in China].

0507BS3 virus was isolated from a mixed pool of Culex sp. and Anopheles sp. collected in Kashi, Xinjiang, China.

Tahyna virus and human infection, China.

In 2006, Tahyna virus was isolated from Culex spp. mosquitoes collected in Xinjiang, People's Republic of China. In 2007, to determine whether this virus was infecting humans, we tested serum from febrile patients.

[Change of knowledge rate after health education on visceral leishmaniasis among residents in a township of Kashgar City].

Health education activities including distribution of brochures, posters, and lectures were conducted in selected villages of a kala-azar endemic-township, Kashi city of Xinjiang in 2004-2006. Questionnaire was carried out before and after health education in residents and students. The percentage of correctly answering all 5 questions on leishmaniasis in residents and primary/secondary school students increased from 0.

Isolation and characterization of the full coding sequence of a novel densovirus from the mosquito Culex pipiens pallens.

During an investigation of arboviruses in China, a novel densovirus (DNV) was isolated from the adult female Culex pipiens pallens.
