Abstract
Adult ticks (Ornithodoros moubata porcinus) collected from warthog burrows were tested for infection by examining their excretions for African swine fever virus (ASFV). All of 3 infected female ticks from one burrow transmitted virus to their eggs and nymphal offspring and filial infection rates were high (55- 81%). Nymphae infected transovarially transmitted virus regularly by feeding on pigs. Four pools of unfed first-stage nymphal ticks, collected from warthog burrows, contained ASFV. Transovarial infection of the tick is one of the natural maintenance mechallisms for ASFV
