Phylogeny of Cache Valley virus (CVV) isolates in mosquitoes collected in Blacksburg, Virginia, USA (GenBank accession nos. KX583998 and KX583999), and reference isolates. The tree was inferred from the medium RNA segment of the virus polyprotein gene and estimated by using mixed model partitioned Bayesian analysis. State, year, host, and GenBank accession number are listed for each isolate. Historical lineages (1 and 2) of CVV are indicated. Shading in lineage 2 indicates strains isolated in this study. The closely related Fort Sherman virus from Panama (accession no. AF234767) is not included. Scale bar indicates expected nucleotide substitutions per site. Ae., Aedes; An., Anopheles; Cq., Coquillettidia; Cx., Culex; Oc., Ochlerotatus.
