摘要
Anaplasmosis in animals is caused by Anaplasma spp. including A. phagocytophilum, A. marginale, A. centrale, A. ovis, and A. bovis, which are obligate intracellular rickettsial pathogens transmitted by ticks. Infection in animals is considered an important constraint on livestock production. In Korea, the prevalence of Anaplasma spp. has been investigated in several species, including cattle, dogs, and rodents, but there are no available data on anaplasmosis in goats. The purpose of this study was to investigate the presence of Anaplasma spp. in native Korean goats (Capra hircus coreanae) using a commercial competitive ELISA which specifically detects antibodies against A. marginale, A. centrale, and A. ovis. A total of 36 (6.6%) of 544 goat serum samples tested seropositive for Anaplasma spp. With regard to age, 4.9% (7/144), 9.5% (27/283), and 1.7% (2/117) of samples tested seropositive in the young (< 1 year), adult (≥ 1 year), and unknown age groups, respectively, with significant differences among groups (P < 0.05). The seroprevalence by region was 1.7% (2/121), 2.6% (2/77), and 9.2% (32/346) in the northern, central, and southern regions, respectively, with significant differences among regions (P < 0.05). With regard to the season of sample collection, 3.3% (4/122) and 7.6% (32/422) samples tested seropositive during the cold and warm seasons, respectively. To the best of our knowledge, this is the first known study reporting the seroprevalence of Anaplasma spp. in native Korean goats. Despite the relatively low prevalence of Anaplasma spp. in native Korean goats compared with that in animals from other countries, these results should not be disregarded because infection with Anaplasma spp. in animals has long been recognised, and the potential for horizontal transmission cannot be excluded.

动物的无形体病是由无形体属（Anaplasma spp）引起的。包括A. phagocytophilum，A。marginale，A。centrale，A。ovis和A. bovis，它们是由蜱传播的专性细胞内立克次体病原体。动物感染被认为是畜牧生产的重要制约因素。在韩国，无形体属的流行。已经在几个物种中进行了调查，包括牛，狗和啮齿动物，但没有关于山羊无形体病的数据。这项研究的目的是调查无形体属的存在。在韩国本土山羊（Capra hircus coreanae）中使用商业竞争ELISA，特异性检测针对A. marginale，A。centrale和A. ovis的抗体。总共36个（6.6％）的544个山羊血清样本测试了无形体属的血清阳性。关于年龄，4.9％（7/144），9.5％（27/283）和1.7％（2/117）的样本在年轻（<1岁），成人（≥1年）中测试血清反应阳性，未知年龄组各组间差异有显着性（P <0.05）。北部，中部和南部地区的血清阳性率分别为1.7％（2/121），2.6％（2/77）和9.2％（32/346），各地区之间存在显着差异（P <0.05） ）。关于样品采集季节，3.3％（4/122）和7.6％（32/422）样品分别在冷和暖季测试血清反应阳性。据我们所知，这是第一个报道无形体属的血清阳性率的研究。在韩国本土山羊。尽管无形体属的流行率相对较低。在韩国本土山羊与其他国家的动物相比，这些结果不应该被忽视，因为感染了无形体属。在动物中早已被认识到，并且不能排除水平传播的可能性。
