Figure. Phylogenetic relationship of 110 Crimean-Congo hemorrhagic fever virus sequences obtained from this study (6 tick pools), the positive control, and 99 published isolates from GenBank. Sequences were aligned by using ClustalX (www.clustal.org), and a phylogenetic tree was constructed by using MEGA4 (neighbor-joining, Kimura 2-parameter, complete deletion of missing data, tree condensed when bootstrap calculated branch support was <0.5) (www.megasoftware.net). The 2 shaded areas indicate clustering of African isolates (AFR) and predominantly European isolates (EUR); unshaded isolates originate primarily from the Middle East.
