Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at characterizing tabanid flies collected in these two countries as well as detecting protozoan parasites they are harbouring. A total of 527 tabanid flies were collected whereby 70·2% were from South Africa and 29·8% were from Zambia. Morphological analysis revealed a total of five different genera collected from the sampled areas namely: Ancala, Atylotus, Haematopota, Philoliche and Tabanus. DNA extracted from South African Tabanus par and Tabanus taeniola tested positive for the presence of Trypanosoma congolense (Savannah) and Trypanosoma theileri whilst one member from T. par was positive for Trypanosoma brucei species. DNA extracted from Zambian tabanid flies tested positive for the presence of Besnoitia species at 1·27% (2/157), Babesia bigemina 5·73% (9/157), Theileria parva 30·11% (30/157) and 9·82% (14/157) for Trypanosoma evansi. This study is the first to report on relationship of Babesia and Theileria parasites with tabanid flies. Further investigations are required to determine the role of tabanids in transmission of the detected protozoan parasites in livestock and wildlife in South Africa and Zambia.
虻是吸食家畜和野生动物血液的苍蝇。由于缺乏关于南非和赞比亚虻蝇与原生动物寄生虫关系的信息，本研究旨在对这两个国家采集的虻蝇进行特征描述，并检测它们体内携带的原生动物寄生虫。总共收集了527只虻蝇，其中70.2%来自南非，29.8%来自赞比亚。形态学分析显示，从采样地区共收集到五个不同的属，即：鞍斑虻属、阿氏虻属、斑虻属、螯虻属和虻属。从南非的平行虻和带纹虻中提取的DNA检测出刚果锥虫（萨凡纳型）和泰勒锥虫呈阳性，而平行虻的一个样本对布氏锥虫属呈阳性。从赞比亚虻蝇中提取的DNA检测出贝斯诺孢子虫属的存在率为1.27%（2/157），双芽巴贝斯虫为5.73%（9/157），小泰勒虫为30.11%（30/157），伊氏锥虫为9.82%（14/157）。本研究首次报道了巴贝斯虫和泰勒虫寄生虫与虻蝇的关系。需要进一步调查以确定虻在南非和赞比亚家畜和野生动物中检测到的原生动物寄生虫传播中的作用。
