Anaplasmosis is a tick-borne disease that has a severe impact on livestock production and welfare. The aim of this pilot study was to investigate the presence of spp. and associated antibodies in a subset of the Swedish goat population. In 2020, six goat herds located in different parts of Sweden were visited and whole blood and serum samples were collected. The whole blood samples ( = 40) were analysed for the presence of , and using quantitative and conventional polymerase chain reaction (PCR). The serum samples ( = 59) were analysed for the presence of antibodies to spp. using a commercial competitive enzyme-linked immunosorbent assay, and the same analysis was carried out on additional serum samples previously collected in 2018, 2019 and 2020 ( = 166). One goat (2.5%) tested positive for the presence of genetic material, while the seropositivity rate ranged from 20 to 71%, depending on the surveyed year and area. These results indicate widespread exposure to spp. in the Swedish goat population. To inform future risk assessments and control efforts, further research is warranted to determine the prevalence of anaplasmosis and its impact on goat farming in Sweden.
无形体病是一种由蜱传播的疾病，对畜牧业生产和动物健康有严重影响。这项初步研究的目的是调查瑞典部分山羊群体中无形体属物种及相关抗体的存在情况。2020年，走访了瑞典不同地区的六个山羊群，并采集了全血和血清样本。对40份全血样本进行定量和常规聚合酶链反应（PCR）分析，以检测嗜吞噬细胞无形体、边缘无形体和双芽巴贝斯虫的存在。对59份血清样本使用商业竞争酶联免疫吸附测定法分析无形体属物种抗体的存在情况，并对先前在2018年、2019年和2020年采集的另外166份血清样本进行了同样的分析。一只山羊（2.5%）检测出嗜吞噬细胞无形体遗传物质呈阳性，而血清阳性率根据调查年份和地区在20%至71%之间。这些结果表明瑞典山羊群体中广泛接触无形体属物种。为了为未来的风险评估和防控工作提供信息，有必要进一步研究以确定无形体病在瑞典的流行情况及其对山羊养殖的影响。
