Low-density macroarray for rapid detection and identification of Crimean-Congo hemorrhagic fever virus.

ABSTRACT: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral zoonosis which occurs throughout Africa, Eastern Europe, and Asia and results in an approximately 30% fatality rate. A reverse transcription-PCR assay including a competitive internal control was developed on the basis of the most up-to-date genome information. Biotinylated amplification products were hybridized to DNA macroarrays on the surfaces of polymer supports, and hybridization events were visualized by incubation with a streptavidin-horseradish peroxidase conjugate and the formation of a visible substrate precipitate. Optimal assay conditions for the detection of as few as 6.3 genome copies per reaction were established. Eighteen geographically and historically diverse CCHF virus strains representing all clinically releva
