The occurrence of group specific complement fixing antibodies was studied in 361 cattle sera from 36 herds in 6 areas in Finland. Sixty-two (17.2%) were positive. The antibody frequency increased significantly from the south to the north and the frequency was significantly higher in forest than in field pastures. The reasons for the differences are discussed. The tick, Ixodes ricinus, perhaps has no significant epidemiological role in chlamydial epidemiology in Finland.
对来自芬兰6个地区36个牛群的361份牛血清进行了群特异性补体结合抗体出现情况的研究。其中62份(17.2%)呈阳性。抗体频率从南向北显著增加,且森林地区的频率显著高于田间牧场。文中讨论了造成这些差异的原因。蓖麻硬蜱在芬兰衣原体流行病学中可能没有显著的流行病学作用。
