flaviviridae are viruses that cause several diseases including dengue fever, japanese encephalitis, murray valley encephalitis, tick-borne encephalitis, west nile encephalitis, yellow fever and hepatitis c virus infection. members of this family have monopartite, linear, single-stranded rna genomes of positive polarity, 9.6-12.3 kb in length. here, we have analyzed the codon usage of 13 species...

We investigated Japanese encephalitis virus (JEV) prevalence in high-altitude regions of Tibet, China, by using standard assays to test mosquitoes, pigs, and humans. Results confirmed that JEV has spread to these areas. Disease prevention and control strategies should be used along with surveillance to limit spread of JEV in high-altitude regions of Tibet.

Japanese encephalitis virus (JEV) is a fatal disease in Asia. Pigs are considered to be the effective amplifying host for JEV in the peridomestic environment. Bali Island and Java Island in Indonesia provide a model to assess the effect of pigs on JEV transmission, since the pig density is nearly 100-fold higher in Bali than Java, while the geographic and climatologic environments are equivalen...

Seasonal prevalence of members of the Culex vishnui subgroup, the major vectors of Japanese encephalitis virus (JE) in an endemic district of Andhra Pradesh, was investigated. Approximately 15,500 mosquitoes belonging to 2 genera and 5 species were collected by indoor-resting collections. The predominant species were found to be from the Cx. vishnui subgroup, which comprised 42.6% of the total ...

BACKGROUND Although a previous study predicted that Japanese encephalitis virus (JEV) originated in the Malaysia/Indonesia region, the virus is known to circulate mainly on the Asian continent. However, there are no reported systematic studies that adequately define how JEV then dispersed throughout Asia. METHODOLOGY/PRINCIPAL FINDINGS In order to understand the mode of JEV dispersal througho...

A 240-nucleotide sequence of the capsid/premembrane gene region of 23 Japanese encephalitis virus (JEV) strains isolated in Tokyo and Oita, Japan was determined and phylogenetic analyses were performed. All the strains clustered into two distinct genotypes (III and I). All strains isolated before 1991 belonged to genotype III, while those isolated after 1994 belonged to genotype I. In addition,...

OBJECTIVE To investigate the role of Anopheles subpictus Grassi as a vector of Japanese encephalitis virus (JEV) transmission in Cuddalore, an area of Tamil Nadu endemic for the disease. METHOD We collected 98 pools (4,900 specimens) of wild adult male An. subpictus mosquitoes outdoors during dusk hours and screened them for JEV antigen by antigen-capture Enzyme Linked Immunosorbent Assay. Ad...

Phylogenetic analysis of Japanese encephalitis virus (JEV) was conducted using core-premembrane and envelope gene sequence data of two strains from Vientiane, Lao People's Democratic Republic, in 1993 and five from Okinawa, Japan, in 2002 and 2003, and previously published strains. The two Vientiane strains designated as LaVS56 and LaVS145 belonged to genotype 1 (G1) and the same subcluster of ...

Japanese encephalitis virus (JEV) (Flaviviridae, Flavivirus) is an arthropod-borne flavivirus transmitted by Culex species mosquitoes. We report here the complete genome of the JEV genotype I strain JEV_CNS769_Laos_2009 isolated from an infected patient in Vientiane, Lao People's Democratic Republic (PDR) (Laos).

Forty-one children with acute laboratory confirmed Japanese encephalitis were studied. Serum iron concentrations were consistently low following Japanese encephalitis virus infection, with the levels being of prognostic significance.
