Figure. Phylogenetic analysis of Alkhurma viruses isolated from Ornithodoros savignyi and Hyalomma dromedarii ticks in Najran Province, Kingdom of Saudi Arabia. A 390-bp region of the core protein C and preM genes was amplified and sequenced for each of the isolates (HQ443410–6) by using primers ALK244S (5′-GTGTTGATGCGCATGATGGG-3′) and ALK665R (5′-TGCAGAAACAGTCCACATCA-3′). A maximum-likelihood analysis was conducted with available sequences in GenBank for ALK (NC_004355; 3) by using Kyasanur Forest disease (AY323490) as the outgroup and the default settings in GARLI version 0.96b8 (www.phylo.org/pdf_docs/zwicklDissertation.pdf).
