Genetic Variation in the Domain II, 3' Untranslated Region of Human and Mosquito Derived Dengue Virus Strains in Sri Lanka.

ABSTRACT: Genetic variations in dengue virus (DENV) play a distinct role in epidemic emergence. The DENV 3' UTR has become a recent interest in research. The objective of the study was to examine the genetic variation in the domain II, 3' UTR region of human and mosquito-derived DENV. DENV-infected human sera were orally infected to laboratory reared Aedes aegypti mosquitoes. The domain II, 3' UTR of each human- and mosquito-derived sample was amplified. The nucleotide sequence variation, phylogenetic and secondary structure analysis was carried out incorporating respective regions of so far recorded Sri Lankan and the reference genotype strains of the DENV3 and DENV1 serotypes. The human- and mosquito-derived domain II, 3' UTR were identical in nucleotide sequences within the serotypes isola
