Ticks of the Ornithodoros moubata complex were collected from domestic pig sties and dwelling houses, and from a warthog habitat, and tested for the presence of African swine fever (ASF) virus. Collections were made in 9 of the 24 districts of Malawi, these being primarily the districts in which O. moubata is most numerous. ASF virus was isolated from ticks collected in both domestic pig sties and houses in certain villages in Mchinji district where ASF outbreaks had recently occurred. Mchinji district is in the centre of a large ASF enzootic area which stretches into other districts of Malawi and also into Zambia and Mozambique. The high titre of virus in some of the ticks demonstrates that O. moubata can act as a virus reservoir and potential vector of disease in the field situation in Malawi.
从家猪猪圈、住宅以及疣猪栖息地采集了莫氏钝缘蜱复合体的蜱，并检测其是否存在非洲猪瘟（ASF）病毒。采集工作在马拉维24个区中的9个区进行，这些区主要是莫氏钝缘蜱数量最多的区。在姆钦吉区某些近期发生过ASF疫情的村庄，从家猪猪圈和住宅采集的蜱中分离出了ASF病毒。姆钦吉区位于一个大型ASF地方病流行区的中心，该流行区延伸至马拉维的其他区，还延伸至赞比亚和莫桑比克。部分蜱中病毒的高滴度表明，在马拉维的野外环境中，莫氏钝缘蜱可作为病毒储存宿主和潜在的疾病传播媒介。
