The objective of the present study was to gain new insights into the evolution, homologous recombination, and selection pressures imposed on the porcine torovirus (PToV), by examining the changes in the hemagglutinin–esterase (HE) gene. The most recent common ancestor of PToV was estimated to have emerged 62 years ago based upon HE gene sequence data obtained from PToV isolates originating from Spain,...
The periodic and recent outbreaks of endemic Chikungunya virus (CHIKV) infection have jeopardized the public health in wider geographical regions. Particularly, full genome-based phylogenetic analyses and recombination of CHIKV have rarely been reported. In this study, phylogenetic and recombination analyses were performed on 122 complete CHIKV genomes. Three major phylogroups were identified which...
