Serological investigation of brucella infection using a dipstick assay among individuals with unexplained fever in farming-pastoral areas of Xinjiang, China.

Objective: To evaluate the brucellosis detection of the dipstick assay coated with LPS antigen from Brucella melitensis vaccine strain M5 compared with Rose Bengal test (RB) and serum agglutination test (SAT), and investigate the brucella infection with the dipstick assay among people with unexplained fever in farming-pastoral areas of Xinjiang, China.

Methods: The dipstick assay was repeated to verify 130 positive and 200 negative serum samples, which had been confirmed by RB and SAT, for sensitivity and specificity analysis. Subsequently, 313 sera from people with unexplained fever in farming-pastoral areas including 6 counties in 3 regions where brucellosis is endemic and 200 sera from nonendemic city area (Urumqi City) in Xinjiang were detected with the dipstick assay for population infection rate survey.

Molecular evidence of Tula virus in Microtus obscurus in the region of Yili, Xinjiang, China.

Background: Hantaviruses are important zoonotic pathogens, and they pose a profound risk to public health. So far, there has been no evidence showing that Tula virus (TULV), one species of hantavirus, is endemic in China. In this study, we captured rodents and found that the Tula virus had infected voles in Yili region, Xinjiang, China.

Seoul virus in the Brown Rat ( Rattus norvegicus ) from Ürümqi, Xinjiang, Northwest of China.

Hantavirus infections among human populations are linked to the geographic distribution of the host rodents that carry the viruses. To determine the presence and distribution of hantaviruses in the northern region of Xinjiang Uygur Autonomous Region (XUAR), northwestern China, 844 rodents were captured from five locations in four dissimilar habitats during 2010-14 and examined for Hantavirus infection. Hantavirus nucleic acids were firstly detected in the brown rat ( Rattus norvegicus ) from Ürümqi, China, indicating that the Hantavirus was transmitted into Ürümqi in XUAR and circulated by the brown rat.
