RIBEIRO, H. & RAMOS. H. Cunha -- <str<strong>on</strong>g>Research</str<strong>on</strong>g> o <strong>the</strong> <strong>mosquitoes</strong> <strong>of</strong> Agola -- X<br />
viruses in nature (96) (97). In Africa, this was shown to be <strong>the</strong> case <strong>of</strong> <strong>the</strong><br />
Germist<strong>on</strong>, Sindbis, Wesselsbr<strong>on</strong>, West Nile, Banzi, Ingwavuma and<br />
Olifantsvlei arboviruses, <strong>the</strong> first four <strong>on</strong>es known to occur also am<strong>on</strong>g<br />
human populati<strong>on</strong>s in <strong>Angola</strong> (98). C. thalassius, in turn, was shown by<br />
Kerr (99) to be a potencial vector <strong>of</strong> <strong>the</strong> Yellow Fever virus.<br />
Species <strong>of</strong> <strong>the</strong> sec<strong>on</strong>d group may be particularly important in c<strong>on</strong>veying<br />
viruses from <strong>the</strong> wild animal reservoir into human communities.<br />
Banzi, Germist<strong>on</strong> and Witwatersrand arboviruses were isolated from<br />
C. rubinotus in South Africa, while C. <strong>the</strong>ileri is a proven carrier <strong>of</strong> Germist<strong>on</strong>,<br />
Rift Valley Fever, Shuni, Sindbis and West Nile viruses.<br />
AB viruses are also associated with some species in <strong>the</strong> third group.<br />
Acado virus was isolated from a mixed pool <strong>of</strong> C. antennatus and C. univittatus<br />
in Ethiopia, while univittatus was found to be naturally infected<br />
in Africa with <strong>the</strong> viruses Ingwavuma, Mossuril, Sindbis, Sp<strong>on</strong>dweni,<br />
Usutu, Wesselsbr<strong>on</strong> and West Nile and was shown to be an experimental<br />
vector <strong>of</strong> Banzi, Sindbis and West Nile arboviruses (100). C. p. pipiens, in<br />
turn, was found naturally infected with Olifantsvlei virus in South Africa,<br />
Sudan and Ethiopia, with Tahjna virus in Kenya, Moambique and<br />
Europe and, quite recently, with viruses Sindbis and West Nile, also in<br />
South Africa (101).<br />
In <strong>the</strong> fourth group <strong>of</strong> species, Sindbis arbovirus was isolated from<br />
wild C. tigripes females in <strong>the</strong> Transvaal.<br />
Lastly, let us menti<strong>on</strong> that in <strong>the</strong> Oriental Regi<strong>on</strong> C. p. quinque/asciatus,<br />
C. bitaeniorhynchus and C. tritaeniorhynchus are known carriers<br />
<strong>of</strong> o<strong>the</strong>r AB viruses, as well as vectors <strong>of</strong> human filariasis (36) (97) (102).<br />
On <strong>the</strong> o<strong>the</strong>r hand, <strong>the</strong> role <strong>of</strong> C. p. quinque/asciatus as a sec<strong>on</strong>dary<br />
vector <strong>of</strong> bancr<strong>of</strong>tian filariasis in Tropical Africa is also now well established<br />
(103).<br />
