Complete Genomic and Ultrastructural Analysis of a Nam Dinh Virus Isolated from Culex pipiens quinquefasciatus in China.

ABSTRACT: The Nam Dinh virus (NDiV) was isolated from Culex quinquefasciatus in Shenzhen, China, for the first time, in 2011. In this study, we characterized the ultrastructure of NDiV, determined its complete genome sequence and made comparisons with other known nidoviruses. Electron microscopic observation revealed that the NDiV strain isolated in China produced viral nucleocapsid-like particles and vesicles in host cells. The extracellular virions were enveloped and were spherical with short spikes. The complete genome sequence of the newly isolated NDiV was submitted to the GenBank database (GenBank accession number KF522691). Sequencing of the viral genome showed that the homologies of NDiV isolated in China and Vietnam were greater than 94.0% and 89.0% at the nucleotide and amino acid sequence
