| dissemination, replication, and trans-stadial persistence of dugbe virus (nairovirus, bunyaviridae) in the tick vector amblyomma variegatum. | the dissemination and replication of dugbe (dug) virus and its tissue tropisms in the tick vector amblyomma variegatum were examined by immunohistochemical analysis using specific antibody, in situ hybridization with a viral-complementary riboprobe, and infectivity assays of dissected tissues. dugbe virus was localized in both unfed and feeding adults inoculated as nymphs or orally infected by capillary feeding, and in nymphs infected by capillary feeding. in non-feeding ticks, the main sites of ... | 1991 | 1867347 |
| difference in vector competence of two species of sympatric ticks, amblyomma variegatum and rhipicephalus appendiculatus, for dugbe virus (nairovirus, bunyaviridae). | amblyomma variegatum was shown to be a competent vector of dugbe (dug) virus whereas rhipicephalus appendiculatus was not. when dug virus was taken up orally by a. variegatum nymphs, during capillary feeding, the virus replicated and persisted through moulting to the following adult stage. in contrast, although dug virus replicated in capillary fed r. appendiculatus nymphs, the virus did not persist trans-stadially into the adult stage. if the oral route of infection was by-passed by direct inoc ... | 1989 | 2510418 |

| [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 ... | 1985 | 4028317 |
| ticks and tick-borne viruses from livestock hosts in arid and semiarid regions of the eastern and northeastern parts of kenya. | biodiversity and relative abundance of ticks and associated arboviruses in garissa (northeastern) and isiolo (eastern) provinces of kenya were evaluated. ticks were collected from livestock, identified to species, pooled, and processed for virus isolation. in garissa, rhipicephalus pulchellus gerstacker (57.8%) and hyalomma truncatum koch (27.8%) were the most abundant species sampled, whereas r. pulchellus (80.4%) and amblyomma gemma donitz (9.6%) were the most abundant in isiolo. forty-four vi ... | 2014 | 24605478 |
