Experimental transmission of African swine fever virus by Ornithodoros savignyi (Audouin).
The 'sand tampan', Ornithodoros savignyi, is susceptible to oral infection with African swine fever (ASF) virus in the laboratory. Infected ticks can transmit the virus transstadially and are able to maintain it for at least 106 days. Transmission of ASF virus by infected ticks to healthy pigs was achieved on five separate occasions between 50 and 106 days after infection. Pigs infected in this way developed typical acute African swine fever. The distribution of O savignyi in Africa suggests that this tick could be a natural field vector of ASF.
