Abstract:
Non-Polio EnteroViruses (NPEV) are one of the known causative agents of Acute Flaccid Paralysis (AFP). In the present study, we identified, sequenced and characterized the complete genome of sixty-five Coxsackievirus-A10, an NPEV. These were isolated from stool specimens of AFP cases from Bihar, Karnataka, Kerala, and Uttar Pradesh (UP) states of India. Evolutionary analysis of complete genome (7420 nucleotides) and VP1 gene (894 nucleotides) demonstrates that there are four different intra-typic strains circulating in India which were dissimilar to Chinese strains. First intratypic strain circulating in UP, Bihar, and Karnataka; second in UP and Karnataka; third in UP and Bihar and; fourth was restricted only to Kerala state. The divergence of Kerala strain with respect to all other circulating strain of UP, Bihar and Karnataka states in India is 24%, 24.9%, and 24.4% respectively. Recombinations were observed between few of these strains which might be one of the factors of the observed intra-typic diversity.We report the identification, characterization and phylogenetic analysis of sixty-five Non-Polio Enterovirus (NPEV) isolates, performed during the year 2009–17, causing acute flaccid paralysis in pediatric cases with their divergences and recombinations from four states of India.
