[Ticks of the family Ixodidae in Guinea and the isolation of arboviruses from them. II. Results of virologic and serologic research]. / Kleshchi semeistva Ixodidae Gvinei i vydelenie iz nikh arbovirusov. Soobshchenie II. Rezul'taty virusologicheskikh i serologicheskikh issledovanii.

55697 Ixodidae ticks of 35 species, belonging to 7 genera, were collected in Guinea in 1981-1983. Virological study of 29410 ticks was performed by intracerebral infection of newborn white mice. 49 viral strains were isolated. Authors identified 38 strains of the 8 following arboviruses: Dugbe, Bhanja, CGL-Congo (ecologically connected with ticks), blue tongue virus of sheep and Abadine (association with ticks was found for the first time), Kindia and Forekarya (the new viruses). Serological screening of cattle (by means of agar diffuse precipitation reaction) has demonstrated a wide distribution of isolated viruses in Guinea. Most active circulation was that of Abadine virus. Its peak was observed in the humid season, the period of Amblyomma variegatum imago domination on cattle, this tick being the main source and vector of the virus, as experimentally confirmed.

[Isolation of Rift Valley fever virus from bats in the Republic of Guinea]. / Isolement du virus de la fièvre de la vallée du Rift à partir de chéiroptères en République de Guinée.

Virological investigations of bats performed in the territory of Republic of Guinea permitted for the first time to isolate from the bats Micropteropus pusillus and Hipposideros abae two strains which were identified as R. V. F. V. Serological investigation revealed specific antibodies to R. V. F. V. among natives in 3.3% and among domestic animals in 6.8%. It is supposed that bats are reservoir of this virus. They can transmit agent of R. V. F. by means of mosquitoes or by being part of the native diet.
