A cross-sectional study was done to determine ehrlichiosis seroprevalence and babesiosis prevalence in dogs that were presented to selected veterinary clinics in Harare. Sera from randomly selected dogs were tested for antibodies to spp. using an enzyme-linked immunosorbent assay while microscopy of peripheral blood smears was used to confirm babesiosis. Overall, 75.2% (88/117, 95% CI: 66.2-82.5) of sera samples tested were positive to spp. antibodies while the prevalence of canine babesiosis was 47.9% (56/117, 95% CI: 38.6-57.3). Age, breed, and sex were found not to be associated with the two disease conditions ( > 0.05). Most of the dogs with babesiosis (82.1%, 46/56) were also positive to spp. antibodies. Hypoalbuminaemia (53.8%, 63/117), anaemia (53.0%, 62/117) and thrombocytopaenia (40.2%, 47/117) were the most common laboratory findings. Thrombocytopaenia and hypoalbuminaemia was more pronounced in dogs with babesiosis only while anaemia was more marked in dogs with babesiosis and positive to spp. antibodies.
开展了一项横断面研究，以确定哈拉雷选定兽医诊所中犬埃立克体病血清阳性率和巴贝斯虫病患病率。使用酶联免疫吸附试验对随机选取的犬只血清进行检测，以检测针对 spp. 的抗体，同时利用外周血涂片显微镜检查来确诊巴贝斯虫病。总体而言，所检测的血清样本中有75.2%（88/117，95%置信区间：66.2 - 82.5）对 spp. 抗体呈阳性，而犬巴贝斯虫病的患病率为47.9%（56/117，95%置信区间：38.6 - 57.3）。研究发现年龄、品种和性别与这两种疾病状况均无关联（>0.05）。大多数患有巴贝斯虫病的犬只（82.1%，46/56）对 spp. 抗体也呈阳性。低白蛋白血症（53.8%，63/117）、贫血（53.0%，62/117）和血小板减少症（40.2%，47/117）是最常见的实验室检查结果。血小板减少症和低白蛋白血症在仅患有巴贝斯虫病的犬只中更为明显，而贫血在患有巴贝斯虫病且对 spp. 抗体呈阳性的犬只中更为显著。
