In the Pardubice area, the systematic examinations for Chlamydia-specific antibodies in cattle were started in 1967. In the years 1967-1978 the detectable levels of antibody to Chlamydia were demonstrated in 16.1% of 38,394 sera from cattle and in 18.6% of 5,244 sera from slinking cows. In the year 1979 the percentage of seropositivity in cattle increased significantly to 23.5% of the 4,197 sera examined. Examinations in 1980 revealed that 23.1% of 4,042 sera from cattle, 34.4% of 319 sera from slinking cows and 17.9% of 209 sera from calves were found antibody positive. Over the period from 1974 to 1978 isolates of Chlamydia organisms were obtained from 11.7% of 452 bovine slinks and from 10% of 271 dead or prematurely slaughtered calves. In the years 1979-1981 a total of 775 individuals were subjected to medical and serological examinations for Chlamydia infection using the BIOVETA group antigen. The first group of examinees included 307 farm personnel, attendants to healthy breeds of cattle. Detectable levels of antibody to Chlamydia were recorded in 1.3% of clinically healthy individuals and in 12% of the 75 healthy, randomly selected cows taken care of by this group of personnel. The second group included 280 individuals who were in charge of slinking cows or calves with chlamydial pneumonia, or who were employed in a rendering plant. A total of 7.5% of antibody-positive individuals was found in this group of examinees. Of the 439 calves attended 17.9% had serologic evidence of infection and the 30 dead calves examined were isolate-positive: sera from 176 slinking cows showed positivity in 23.8% of cases. In the third group of 188 persons serving as controls 5.3% had serologic evidence of chlamydial infection. The statistical analysis of deviations from the Gaussian variance normal curve showed neither sex-related nor inter-group differences. At the time of serologic examinations of humans the epidemiologic situation in the given area was extremely favorable. The importance of a close cooperation between the public health and veterinary service personnel (notification of abortions in cattle) and the need of a due attention of gynecologists, dermatologists and urologists are emphasized.
在帕尔杜比采地区，1967年开始对牛进行衣原体特异性抗体的系统检测。1967年至1978年期间，在38394份牛血清中，16.1%检测到衣原体抗体水平；在5244份流产母牛血清中，18.6%检测到抗体。1979年，检测的4197份牛血清中，血清阳性率显著上升至23.5%。1980年的检测发现，4042份牛血清中23.1%、319份流产母牛血清中34.4%以及209份犊牛血清中17.9%抗体呈阳性。1974年至1978年期间，从452头病牛中11.7%以及271头死亡或过早屠宰的犊牛中10%分离出衣原体。1979年至1981年期间，共有775人使用BIOVETA组抗原接受衣原体感染的医学和血清学检测。第一组受检者包括307名农场工作人员，负责健康牛群。在临床健康个体中，1.3%检测到衣原体抗体水平；在该组工作人员照料的75头随机挑选的健康母牛中，12%检测到抗体。第二组包括280名负责流产母牛或患有衣原体肺炎的犊牛的人员，或在提炼厂工作的人员。该组受检者中，共7.5%个体抗体呈阳性。在439头受照料的犊牛中，17.9%有感染的血清学证据，检测的30头死亡犊牛分离结果呈阳性：176份流产母牛血清中，23.8%呈阳性。在作为对照的第三组188人中，5.3%有衣原体感染的血清学证据。对偏离高斯方差正态曲线的统计分析表明，不存在性别相关差异或组间差异。在对人类进行血清学检测时，该地区的流行病学情况极为有利。强调了公共卫生和兽医服务人员密切合作（通报牛流产情况）的重要性，以及妇科医生、皮肤科医生和泌尿科医生给予适当关注的必要性。
