Japanese encephalitis virus (JEV) (Flavivirus: Flaviviridae) is a leading cause of encephalitis in eastern and southern Asia. The virus is maintained in a zoonotic cycle between ardeid wading birds and/or pigs and Culex mosquitoes. The primary mosquito vector of JEV is Culex tritaeniorhynchus, although species such as Cx. gelidus, Cx. fuscocephala, and Cx. annulirostris are important secondary or regional vectors. Control of JEV is achieved through human and/or swine vaccination, changes in…

The Ecology and Evolution of Japanese Encephalitis Virus

Increased surveillance and diagnosis of JE is required as climate change and social disruption are likely to facilitate further geographical expansion of Culex vectors and JE risk areas.

Japanese Encephalitis Enzootic and Epidemic Risks across Australia

Japanese encephalitis virus (JEV) is an arboviral, encephalitogenic, zoonotic flavivirus characterized by its complex epidemiology whose transmission cycle involves reservoir and amplifying hosts,

Potential Role of Birds in Japanese Encephalitis Virus Zoonotic Transmission and Genotype Shift

The role of birds in the J EV zoonotic transmission, discovery of birds as a natural reservoirs and amplifying host for JEV, species of birds susceptible to the JEV infection, and the proposed effect of JEV on the poultry industry in the future are highlighted.

Japanese Encephalitis Virus: An Emerging Pathogen

In India vaccination against Japanese encephalitis are administered in areas where the disease is hyper-endemic, and DNA based vaccines might aid the purpose of combating against JEV which are presently under clinical trials.

Japanese encephalitis: the vectors, ecology and potential for expansion

Increased surveillance and diagnosis of viral encephalitis caused by genotype 5 JE virus is required in particular, with the expansion in epidemiology and disease prevalence in new geographic areas an issue of great concern.

Better characterizing the influence of seasonal temperature variations on JE circulation in pigs in subtropical area and inferring on the potential impact onJE symptomatic infection in reproductive pigs is aimed at better characterizing.

Experimental Evaluation of the Role of Ecologically-Relevant Hosts and Vectors in Japanese Encephalitis Virus Genotype Displacement

evaluating both avian host and mosquito vector susceptibilities to infection with representatives from both G-I and G-III suggested that the characteristics of JEV infection of mosquitoes but not of ducklings, may have play a role in genotype displacement.

Isolation of Japanese encephalitis virus from Culex annulirostris in Australia.

Eight isolates of JE virus were obtained from Culex annulirostris, with a carriage rate of 2.97:1,000; among the isolates, 99% homology was obtained, suggesting a common point of origin.
