Résumé de : BUTENKO (AM) - 1996 - Study of arboviruses in the republic of Guinea. Med. Parasitol. (URSS), Parazit. Bolezni. N° 2, pp. 40-45.


In 1978-1991 the USSR-Guinea Virological and Microbiological Laboratory functioned in Kindia, the Republic of Guinea. Arbovirus activity in this country was studied by a number of virologists and other specialists. Their personal contribution and achievements in this collaboration are reflected in the present paper. About 74,000 mosquitoes, 100,000 Ixodidae ticks, 1,500 wild birds, 2,700 bats, 106 monkeys, and 308 other mammals, 927 blood samples collected from febrile patients were examined in 1978-1989, using inoculation of new-born white mice. As a result of this work 127 strains of the following arboviruses were isolated: Chikungunia (1 strain), Dengue 2 (4), Saboya (7), Wesselsbron (1), Bunyamwera (4), M'Poko (5), Rift Valley Fever (6), CHF-Congo (9), Dugbe (22), Bhanja (6), Forecariah (2), Jos (26), Abadina (15), Kindia (2), Ark 6956 (1), Fomede (2), Bluetongue (9), Mossuril (2), AnK 6009 (1), and Kolente (2). Dengue 2, Wesselsbron, Bunyamwera, M'Poko, Kindia, Mossuril viruses were isolated from mosquitoes. Ixodidae ticks were sources for isolation of Chikungunia, Saboya, CCHF, Dugbe, Bhanja, Forecaciah, Jos, Abadina, Kindia, Ark 6956, Fomede, Bluetongue, and Kolente viruses. Saboya, RVF, Fomede, Kolente, AnK 6909 were isolated from bats (Chiroptera); Saboya, Abadina, and Bluetongue viruses from birds. One strain of Dugbe virus was originated from the brain of Cercopithecus patas. Bunyamwera and Abadina viruses were isolated from the blood of two febrile patients. Serological identification of many strains was kindly conducted at the Pasteur Institute, Dakar (J. P.Digoutte) and some at the YARU, USA (R. Shope). Kindia and Ark 6956 (Reovirus, gr. Palyam), Fomede (gr. Chobar Gorge), Forecariah (Bunyavirus, gr. Bhanja), Kolente (Rhabdovirus) were identified as an original type of Lagos bat virus. The results of seroepidemiological surveys are also presented.
