Studies on the experimental infection of Hyalomma dromedarii (Koch) ticks with tick-born encephalitis virus.

The replication dynamics of 4 strains of tick-borne encephalitis virus, differing in neurovirulence towards white mice, and their penetration to the salivary glands and ovaries of H. dromedarii were examined. The ticks were infected by being artificially fed a large dose of the virus and were observed for 44 days. The virus actively multiplied in whole ticks and examined organs. A relation between the neurovirulence of the strains towards white mice and persistence of infection in the ticks and their organs was observed.
