#Genetic Diversity of the Non-Polio #Enteroviruses Detected in Samples of Patients with Aseptic #Meningitis in the #Ural Federal District and Western #Siberia
Abstract Human non-polio enteroviruses (NPEVs) cause a plethora of infections in humans, ranging from mild to severe neurological diseases including aseptic meningitis . NPEVs are the leading cause of aseptic meningitis in both children and adults worldwide . In Russia , reports of NPEV infections have surged, especially in the post-COVID era starting in 2022, with elevated infection rates into 2023 . A comprehensive examination of the whole genome is crucial for understanding the evolution of NPEV genes and for predicting potential outbreaks. This study focused on identifying the circulating NPEV strains in the Ural Federal District and Western Siberia , using Sanger sequencing and next-generation sequencing (NGS) methodologies. Biological samples were collected from (n = 225) patients diagnosed with aseptic meningitis. Bioinformatics analysis targeted the nucleotide sequences of the major capsid protein (partial VP1) gene fragment, and the assembly of whole NPEV genomes. A tota...
