and are two obligate intracellular protozoan parasites that can cause reproductive failure and production losses. To date, there is no data of and seroprevalence in black goats in Yunnan Province, southwestern China. In the present study, a total of 734 serum samples were collected from black goats in four different counties of Yunnan Province. 734 and 590 serum samples were examined for antibodies against and by using MAT and indirect ELISA, respectively. A total of 123 and 76 samples were positive and -positive, respectively. The overall seroprevalence of in black goats was 16.76% (123/734, 95% CI: 14.06-19.46) with the titer ranged from 1:25 to 1:3200. The seroprevalence of was 12.88% (76/590, 95% CI: 10.18-15.58). There was significant difference in seroprevalence of in different regions ( < 0.01, χ = 30.63) and age groups ( < 0.05, χ = 11.85). Significant differences in seroprevalence of were observed in different regions ( < 0.05, χ = 9.21) and different gender groups ( < 0.01, χ = 12.29). Results of seroprevalence of and indicated that and were prevalent parasites in black goats in Yunnan Province. This is the first report of seroprevalence of and in black goats in Yunnan Province. The results of this study indicated that some measures should be taken to control these two parasites and to reduce economic losses to the livestock industry in Yunnan Province.
[具体寄生虫名称1]和[具体寄生虫名称2]是两种专性细胞内原生动物寄生虫，可导致繁殖失败和生产损失。迄今为止，中国西南部云南省黑山羊中[具体寄生虫名称1]和[具体寄生虫名称2]的血清流行率尚无数据。在本研究中，共从云南省四个不同县的黑山羊中采集了734份血清样本。分别使用微量凝集试验（MAT）和间接酶联免疫吸附测定（ELISA）对734份和590份血清样本检测抗[具体寄生虫名称1]和抗[具体寄生虫名称2]的抗体。分别共有123份和76份样本为[具体寄生虫名称1]阳性和[具体寄生虫名称2]阳性。黑山羊中[具体寄生虫名称1]的总体血清流行率为16.76%（123/734，95%可信区间：14.06 - 19.46），滴度范围为1:25至1:3200。[具体寄生虫名称2]的血清流行率为12.88%（76/590，95%可信区间：10.18 - 15.58）。[具体寄生虫名称1]在不同地区的血清流行率存在显著差异（P<0.01，χ² = 30.63）和不同年龄组间存在显著差异（P<0.05，χ² = 11.85）。[具体寄生虫名称2]在不同地区的血清流行率存在显著差异（P<0.05，χ² = 9.21）以及在不同性别组间存在显著差异（P<0.01，χ² = 12.29）。[具体寄生虫名称1]和[具体寄生虫名称2]的血清流行率结果表明，[具体寄生虫名称1]和[具体寄生虫名称2]是云南省黑山羊中的常见寄生虫。这是云南省黑山羊中[具体寄生虫名称1]和[具体寄生虫名称2]血清流行率的首次报告。本研究结果表明，应采取一些措施来控制这两种寄生虫，并减少云南省畜牧业的经济损失。
