Whole-genome sequencing of a green bush viper reovirus reveals a shared evolutionary history between reptilian and unusual mammalian orthoreoviruses

In this study, we sequenced the whole genome of a reovirus isolated from a green bush viper (Atheris squamigera). The bush viper reovirus shared several features with other orthoreoviruses, including its genome organization. In phylogenetic analysis, this strain was monophyletic with Broome virus and baboon orthoreovirus, indicating that these viruses might have originated from a common ancestor. These new molecular data supplement previous information based mainly on biological properties of reptilian reoviruses, confirming their taxonomic position and broadening our knowledge of the evolution of members of the genus Orthoreovirus

Identification and characterization of a new bocavirus species in gorillas. PLoS One 5: e11948

A novel parvovirus, provisionally named Gorilla Bocavirus species 1 (GBoV1), was identified in four stool samples from Western gorillas (Gorilla gorilla) with acute enteritis. The complete genomic sequence of the new parvovirus revealed three open reading frames (ORFs) with an organization similar to that of known bocaviruses. Phylogenetic analysis using complete capsid and non structural (NS) gene sequence suggested that the new parvovirus is most closely related to human bocaviruses (HBoV). However, the NS ORF is more similar in length to the NS ORF found in canine minute virus and bovine parvovirus than in HBoV. Comparative genetic analysis using GBoV and HBoV genomes enabled characterization of unique splice donor and acceptor sites that appear to be highly conserved among all four HBoV species, and provided evidence for expression of two different NS proteins in all primate bocaviruses. GBoV is the first non-human primate bocavirus identified and provides new insights into the genetic diversity and evolution of this highly prevalent and recentl
