[Isolation of Thogoto virus from Amblyomma and Boophilus ticks in Central Africa].

A survey has been carried out in the Cameroons and the Central African Republic about the role of the ticks in the ecology of arboviruses in Central Africa. Attempts for virus isolation were made for 12,678 Amblyomma variegatum, 3,276 Boophilus decoloratus and 1,769 Boophilus annulatus, by inoculation into suckling mice. From 968 pools which were inoculated, 20 yielded isolates which were identified to Thogoto virus. Considering previously published results concerning tick-borne virus isolations in the Central African Republic, it appears now that five arboviruses are present in the ticks in central Africa : Dugbe, Jos and Thogoto (in A. variegatum, B. decoloratus and B. annulatus), Bhanja (in A. variegatum) and Chf. Congo (in Hyalomma nitidum).
