在津巴布韦哈拉雷一家兽医医院检查的 105 只狗中，52% 的狗在间接荧光抗体测试中发现了与犬埃利希体反应的抗体，26% 的外周血涂片中发现了犬巴贝斯虫寄生虫，17% 的狗同时感染了这两种寄生虫。具有埃立克体病血清学证据的狗均未在血涂片中检测到典型的犬桑葚病。这些感染被认为是偶然发现的，与检查原因无关，在 46% 的携带犬大肠杆菌抗体的狗和 17% 的同时感染两种感染的狗中，这些感染被认为与检查原因无关。最常见的实验室异常是贫血和血小板减少，并发感染中这些异常的患病率和严重程度中等于个体感染中发现的异常。没有可用于区分个体感染和并发感染的特征性临床症状或实验室异常。然而，携带犬艾美耳球虫抗体的狗中非再生性贫血的患病率明显高于同时感染这两种病毒的狗。患有巴贝斯虫病的狗的血小板减少症患病率显着高于具有犬艾美耳球虫抗体的狗，并且患有两种感染的狗的高球蛋白血症患病率显着高于具有犬艾美耳球虫抗体的狗。
Of 105 dogs examined at a veterinary hospital in Harare, Zimbabwe, 52 per cent had antibodies reactive with Ehrlichia canis in indirect fluorescent antibody tests, 26 per cent had Babesia canis parasites in peripheral blood smears and 17 per cent had both infections. None of the dogs with serological evidence of ehrlichiosis had typical E canis morulae detectable in blood smears. The infections were regarded as incidental findings not readily related to the reasons for examination in 46 per cent of the dogs with antibodies to E canis and 17 per cent of the dogs with both infections. The most common laboratory abnormalities were anaemia and thrombocytopenia and the prevalence and severity of these in concurrent infections were intermediate to those found in individual infections. There were no pathognomonic clinical signs or laboratory abnormalities which could be used to distinguish between individual and concurrent infections. However, there was a significantly higher prevalence of non-regenerative anaemia in dogs with antibodies to E canis than in dogs with both infections. The prevalence of thrombocytopenia was significantly higher in dogs with babesiosis than in dogs with antibodies to E canis and the prevalence of hyperglobulinaemia was significantly higher in dogs with both infections than in dogs with antibodies to E canis.
