Abstract
We examined the potential for Hyalomma impeltatum Schulze & Schlottke ticks to transmit Crimean-Congo hemorrhagic fever (CCHF) virus. After feeding on 1-d-old mice that had been inoculated with CCHF virus, larval H. impeltatum became infected with and subsequently transmitted CCHF virus transstadially to nymphs. These nymphs transmitted virus horizontally to guinea pigs and transstadially to adults. A minimum of 13% of the adult H. impeltatum , exposed to virus as larvae, transmitted virus by bite to guinea pigs. An enzymelinked immunosorbent assay detected CCHF viral antigen in 63% of the adult ticks derived from those exposed to this virus as larvae. This tick species should be considered as a potential vector of CCHF virus.Keywords
