[ecology of tick-borne arboviruses in the central african republic].ticks have been collected on cattle skins for seven consecutive years in bangui, berberati, bangassou and bouar. 150 strains of arboviruses have been isolated from the four following species: amblyomma variegatum: dugbe, jos, thogoto, crimean-congo hemorragic fever (cchf), yellow fever, bhanja and pétévo; boophilus annulatus: dugbe, jos and thogoto; b. decoloratus: dugbe, jos, thogoto and cchf; hyalomma nitidum: cchf. dugbe (112 isolated strains), jos (19 isolates) and thogoto (11 isolates) viru ...19854028317
[experimental transmission of the yellow fever virus by the tick amblyomma variegatum (f.) (author's transl)].experimental transmission of the yellow fever virus by the tick amblyomma variegatum (f.) (the tropical bont tick) is demonstrated for the first time. the tick transmitted the virus from one monkey to another. trans-stasial passage from nymph to adult stage was also demonstrated. the possible role of amblyomma variegatum as a vector and a potential reservoir of yellow fever is discussed.19827105284
[isolation of the yellow fever virus from an egg-cluster and the larvae of the tick amblyomma variegatum].the yellow fever virus is isolated in natura from eggs of a tick amblyomma variegatum. it is then isolated from larvae issued from the same egg-cluster and also from blood of a monkey bitten by larvae of the same origin. it is reported that the same virus has been previously obtained from adults of the same species of tick. an acarine appears for the first time as a sylvatic vector and reservoir (at least temporary) of yellow fever.1979117946
