title: Complete genome sequence analysis of human echovirus 30 isolated during a large outbreak in Guangdong Province of China, in 2012.
abstract: In May and June 2012, an outbreak of aseptic meningitis caused by Echovirus 30 (E30) occurred on a large scale in Luoding, Guangdong Province, China. Our team successfully isolated one subtype, strain 2012EM161, and its complete genome was sequenced. The phylogenetic tree of viral protein (VP) 1 gene sequences showed that the viral isolate was similar to the E30 strain prevalent in Fujian (2011), with identity of 98.05-99.32 % and 98.63-99.32 % for nucleotides and amino acids respectively. Whole genome-based phylogenetic analysis indicated that 2012EM161 contained the most proximate consensus to DQ246620 (Zhejiang, 2003) and FDJS03 (AY948442, Jiangsu, 2005), with nucleotide homogeneity of 87.09 % and 86.98 % respectively. The RDP4.16 and Simplot analysis showed that the newly discovered 2012EM161 was probably a recombinant, which was closely related to the strain of E30 (DQ246620) in the first half of the genome and the strain of E6 (JX976771) in genomic P3 region. The whole genome sequence of 2012EM161 will allow further study of the origin, evolution, and the molecular epidemiology of E30 strains.
