Abstract

Chlamydial complement fixing antibodies were followed in 5 small Finnish dairy herds. All 53 animals in the herds were bled. In herds A, B, C and D the blood samples were collected in May and in the following autumn after the pasturing period and in herd E over a period of 2 years at about 1 ½-month intervals. The frequencies of positive reactions among the adults and the calves younger than 1 year did not differ significantly from each other, but there were considerable seasonal variations in the frequencies. The highest frequency was found during springtime and early summer and the lowest in autumn.

摘要

在芬兰的5个小型奶牛场中追踪衣原体补体结合抗体。对这些奶牛场中的所有53头动物进行了采血。在A、B、C和D奶牛场，于5月以及放牧期后的次年秋季采集血样，而在E奶牛场，则在2年时间里每隔约1个半月采集一次血样。成年动物和1岁以下犊牛的阳性反应频率彼此之间没有显著差异，但频率存在相当大的季节性变化。春季和初夏时频率最高，秋季最低。
