In common with all nonenveloped viruses, the mechanism of picornavirus membrane penetration during cell entry is poorly understood. The small, myristylated capsid protein VP4 has been implicated in this process. Here we show that recombinant VP4 of human rhinovirus 16 has the ability to associate with and induce membrane permeability in otherwise intact liposomes. This provides further evidence that VP4 plays a key role in picornavirus cell entry.

Introduction: This study, conducted in China prior to RotaTeq's launch, examined the epidemiological, molecular, and evolutionary features of the G1P[8] genotype RVA in children admitted with diarrhea, to aid in evaluating its efficacy and impact on G1P[8] RVA in China.
Methods: Data from the Chinese viral diarrhea surveillance network were collected from January 2016 to December 2018. RVA strains identified as the G1P[8] genotype were subjected to whole-genome sequencing.

Group A rotaviruses (RVAs) are a major cause of acute gastroenteritis in children under 5 years of age worldwide. Herein, the genetic sequences of 11 RNA segments from three uncommon G9P[4] RVA strains found in the stool samples of children under 5 years of age in Iran were analyzed using next-generation sequencing (NGS) technology. The genomic constellations of these three uncommon G9P[4] strains indicated the presence of the double and quadruple reassortants of two G9P[4] strains, containing the VP7/NSP2 and VP7/VP2/NSP2/NSP4 genes on a DS-1-like genetic background, respectively.
