Abstract
Menghai flavivirus MFV was isolated from Aedes albopictus in Menghai county of Yunnan Province China during an arboviruses screening program in August 2010 Whole genome sequencing of MFV was performed using an Ion PGM™ Sequencer The complete genome of MFV was 10897 nucleotides in length and encoded a polyprotein and fairly interesting flavivirus orf FIFO The polyprotein contained three flavivirus structural proteins C prM/M and E and seven nonstructural proteins Nucleotide BLAST analysis revealed that the MFV genome showed highest similarity to Xishuangbanna Aedes flavivirus a novel insectspecific flavivirus recently isolated from the same area These species shared a query cover of 99 but only 71 identity while FIFO showed no similarity with any of the published sequences Genomic and phylogenetic analyses suggested that MFV was a novel species of the genus Flavivirus Our findings enrich our understanding of the genetics and prevalence of the family FlaviviridaeThis research was supported by grants from the National Natural Science Foundation of China No 81273138 and No 81572045 the China MegaProject on Infectious Disease Prevention No 2013ZX10004605 No 2013ZX10004607 No 2013ZX10004217 and No 2011ZX10004001 and the National HiTech Research and Development 863 Program of China No 2014AA021402 No 2012AA022003 and No 2015AA020108
