Аннотация
BACKGROUND: Japanese encephalitis (JE) causes inflammation of brain. The mortality rate due to JE is 30% while 10 -15 % of patients make full recovery. The disease spreads through infected mosquito bites breeding in rice fields and feeds on pigs, birds, and ducks.
PURPOSE: As proteins show important structure to function relationship the study was designed to carry out the identification of poly and non-structural proteins in the infective virus group using different strains of Japanese encephalitis virus i.e. JAOARS982, Nakayama Strain SA (V), Strain SA-14.
METHODS: With reference to non structural proteins we obtained protein sequences of the following Japanese encephalitis virus groups: Japanese encephalitis virus, Weatnile virus, Kunjin virus. Further comparative and phylogenetic analysis was performed to explore evolutionary relationship among these groups.
RESULTS: Results of phylogeny of alignment score was found to be 375184 using multiple alignment, Jal view, ClustalW (1.83) and ClustalW2. However, the analysis among the non-structural proteins of Japanese Encephalitis Virus, Westnile Virus, and Kunjin Virus revealed the phylogeny alignment score to be 875 through multiple sequence alignment and Tree view respectively.
CONCLUSION: Phylogenetic analysis revealed that these four strains are interrelated as well as showing high similarity with the other viruses of this group due to conserved regions among their sequences.
