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 20
