A study on the presence of Babesia in humans was performed in Puerto Berr o (Latitude 6.50deg. Longitude: -74.38deg. River: Magdalena. Area: 74.410km , Colombia-South America). Indirect immunofluorescence, thin and thick blood smears were used to study 194 individuals. Patients were grouped according to their risk-factors for Babesia infection: (group 1) individuals with fever, chills, sweating and other malaria-type symptoms; (group 2) symptomatic and asymptomatic individuals from local cattle ranches, which were enrolled in an active form, and (group 3) workers from the local slaughterhouse. Seven individuals were serologically positive for Babesia: Three individuals presented IgM antibodies against B. bovis, while one had IgG against this species; one individual had IgM against B. bigemina, another had IgG and a third both IgM and IgG against this species. Only one individual was parasitologically positive for Babesiaand serologically positive for Babesia bovis (IgM 1:64)
在波多贝罗（北纬6.50度，西经74.38度，马格达莱纳河，面积74410平方千米，哥伦比亚 - 南美洲）开展了一项关于人体巴贝斯虫存在情况的研究。采用间接免疫荧光法、薄血涂片和厚血涂片对194人进行研究。患者根据其巴贝斯虫感染风险因素分组：（第1组）有发热、寒战、出汗及其他疟疾样症状的个体；（第2组）来自当地养牛场的有症状和无症状个体，以主动参与形式纳入；（第3组）当地屠宰场的工人。7人巴贝斯虫血清学检测呈阳性：3人出现抗牛巴贝斯虫的IgM抗体，1人有抗该物种的IgG抗体；1人有抗双芽巴贝斯虫的IgM抗体，另1人有抗该物种的IgG抗体，第3人同时有抗该物种的IgM和IgG抗体。仅1人巴贝斯虫寄生虫学检测呈阳性且牛巴贝斯虫血清学检测呈阳性（IgM 1:64）
