Viral Isolates from Ixodid Ticks of Wild Animals in Kenya

  • I. M. Solberg

Approximately 10,000 ixodid ticks were collected over a period of 24 months from 11 species of wild African ungulates. The ticks, sorted by species, were inoculated intracerebrally into infant mice as pools for attempted virus isolation. A total of 11 isolates were made, 8 from 62 pools of Rhipicephalus pulchellus, 2 from 9 pools of Amblyomma variegatum and 1 from 6 pools of Amblyomma cohaerens. Seven isolates were identified as Kadam virus, 1 isolate showed serological relationship with Bhanja virus and 3 isolates, of one antigenic type, remained unidentified. Virus was not isolated from 25 pools of Rhipicephalus evertsi, 11 pools of Rhipicephalus appendiculatus, 2 pools of Amblyomma lepidae, 9 pools of Haemaphysalis species and 4 pools of Hyalomma species.

Ungefahr 10,000 Ixodid-Zecken wurden wahrend 24 Monaten von 11 Arten wildlebender Huftiere Afrikas gesammelt. Die Zecken wurden nach Arten sortiert und im Gruppen (Pools) zusammengefasst. Isolierung von Viren wurde versucht indem Babymause intracerebral mit Extrakten aus diesen Zeckenpools inokuliert wurden. Insgesamt wurden 11 Isolate gefunden, 8 aus 62 Pools von Rhipicephalus pulchellus, 2 aus 9 Pools von Amblyomma variegatum und 1 aus 6 Pools von Amblyomma cohaerens. Sieben Isolate liessen sich als Kadam-Virus identifizieren. 1 Isolat zeigte serologisch Ahnlichkeit mit Bhanja-Virus und 3 Isolate, antigenisch einheitlich, konnten nicht identifiziert werden. Eine Virusisolierung gelang nicht von 11 Pools von Rhipicephalus appendiculatus, 25 Pools von Rhipicephalus evertsi, 2 Pools von Amblyomma lepidae, 9 Pools von Haemaphysalis species und 4 Pools von Hyalomma species.
