Comparative genomics of human rubulavirus 2

Abstract

Although human rubulavirus 2 (HPIV2) is an important respiratory pathogen, little is known about its molecular epidemiology. We performed a comparative analysis of the full-length genomes of fourteen HPIV2 isolates belonging to different genotypes. Additionally, evolutionary analyses (phylogenetic reconstruction, sequence identity, detection of recombination and adaptive evolution) were conducted. Our study presents a systematic comparative genetic analysis that complements prior analyses and utilizes full-length HPIV2 genomes to provide a basis for future work on the clinical significance, molecular variation and conservation, and evolution of HPIV2.
