Dengue fever is an acute mosquito-borne viral disease caused by dengue virus (DENV). Temperature may affect the efficiency of the mosquito vectors in spreading DENV. Aedes albopictus mosquitoes were infected orally with a DENV2 suspension and incubated at different temperatures. Subsequently, DENV2 antigen was collected from salivary gland and(More)
Genotyping of hepatitis C virus (HCV) can provide valuable information for prognosis and treatment duration prediction. To explore the genetic diversity of HCV in Fujian Province, China, 112, 104 and 48 anti-HCV-positive serum samples were collected from volunteer blood donors, IDUs and patients, respectively, from Jan 2008 to Dec 2008 and were genotyped(More)
OBJECTIVE To construct recombinant plasmids containing the truncated gene of the major surface antigen sta56 of Orientia tsutsugamushi (Ot.) Karp strain for expression antigen in E. coli so as to compare the expression efficiency in different systems. METHODS From the recombinant plasmid TOPO-sta56 containing sta56 of Orientia tsutsugamushi Karp strain,(More)
OBJECTIVE To establish recombinant outer membrane lipoprotein LipL32-based antibody detection assays in identifying leptospirosis. METHODS Recombinant leptospiral outer membrane protein LipL32 was obtained by genetic engineering method. This purified protein was used in the indirect and sandwich ELISA assays to test the antibodies in sera of human beings(More)
