Identification of new genotype of Echovirus 19 from children with Acute Flaccid Paralysis in Pakistan.

ABSTRACT: Enteroviruses are known to cause childhood paralysis. The purpose of this study was to examine the genetic diversity and to determine the association of non-polio enteroviruses (NPEVs) with acute flaccid Paralysis (AFP). Stool samples (n = 1191) of children with AFP were collected from Khyber Pakhtunkhwa and Federally Administered Tribal Areas of Pakistan. Poliovirus was isolated in 205 (17.2%) samples and NPEVs were found in 215 (18.0%) samples. Out of 215 viruses, 124 (57.7%) were typed into 19 different types of enteroviruses while 91 (42.3%) remained untypeable on microneutralization assay that were reconfirmed as NPEVs by real time PCR. Echovirus 19 (20/35; 57.1%) was found the most prevalent type based on VP1 nucleotide sequencing with increased genetic diversity. Phylogenetic analys
