Variegated Squirrel Bornavirus 1 in Squirrels, Germany and the Netherlands

View Article: PubMed Central - PubMed

ABSTRACT

We screened squirrels in Germany and the Netherlands for the novel zoonotic variegated squirrel bornavirus 1 (VSBV-1). The detection of VSBV-1 in 11 squirrels indicates a considerable risk for transmission to humans handling those animals. Therefore, squirrels in contact with humans should routinely be tested for VSBV-1.

No MeSH data available.


Analysis of 11 newly identified VSBV-1 genomes from squirrels collected in Germany and the Netherlands, 2015, in comparison with related bornaviruses. A) New sequences aligned with published squirrel-derived VSBV-1 genome (GenBank accession no. LN713680). The upper black bar indicates the reference sequence; gray boxes depict the genome. White bar sections for each animal sequence indicate nucleotide variations. The new sequences show 1–29 nucleotide differences compared to the published prototype sequence. G, glycoprotein; L, large structural protein; M, matrix; N, nucleoprotein; P, phosphoprotein; X, nonstructural protein. B) Phylogenetic tree of VSBV-1 isolates from this study (labeled) and comparison sequences. Tree was constructed using the maximum-likelihood method. Numbers along branches are bootstrap values. GER, Germany; NL, the Netherlands; VSBV-1, variegated squirrel bornavirus 1.

Mentions: Genomes of viruses detected in squirrels from holding I showed the highest similarity with 1–6 nt substitutions, resulting in 1–3 aa changes, whereas the other sequences exhibited more variability. We found <29 nt substitutions causing <19 aa changes. The mutations were evenly distributed over the coding regions, but in viral genomes of squirrels from the same holding, they often occurred at the same position (Figure 2, panel A).
