In a period of three years epidemiological studies were carried out in Styria concerning the occurrence of antibodies against BRSV (Bovine Respiratory Syncytial Virus), Adeno I Species 3-Virus, Adeno II Species 8-Virus, PI-III (Parainfluenza 3-Virus), IBR/IPV-Virus and Chlamydia. A total of 1376 serum samples were examined and showed different titers of specific antibodies against respiratory pathogens. 449 blood samples were submitted to serological examinations in the year 1984, 525 in 1985 and 402 in 1986. Antibodies against BRSV could be found in 17.4% of the sera or in 55.9% of the herds. Specific antibodies against Adeno I Species 3 occurred in 33.9% of the sera resp. in 74.2% of the units. 35.2% of the cows or 80.1% of the herds showed positive SN-titres against Adeno II Species 8. IBR/IPV-specific antibodies were detected in 2.3% of the sera resp. 3.8% of the herds. Antibodies against Chlamydia could be found in 8.8% of the cows or in 22.6% of the units. In the years mentioned above significant differences of antibodies against BRSV, Adeno I Species 3, Adeno II Species 8 and Chlamydia could be observed, but not against PI-III and IBR/IPV as well. By means of the Chi-Square-Test significant differences between Simmentaler, Austrian Brown Cattle and Holstein Friesian regarding antibodies against IBR/IPV and Adeno II Species 8 could be found. No significant differences between the serological results of herds, which contained on of the three breeds could be observed.
在三年时间里，施蒂里亚州开展了关于抗牛呼吸道合胞病毒（BRSV）、腺病毒I型3病毒、腺病毒II型8病毒、副流感3病毒（PI - III）、传染性牛鼻气管炎/传染性脓疱性外阴阴道炎病毒（IBR/IPV）和衣原体抗体出现情况的流行病学研究。共检测了1376份血清样本，这些样本显示出针对呼吸道病原体的不同特异性抗体滴度。1984年有449份血样接受了血清学检查，1985年有525份，1986年有402份。在17.4%的血清中或55.9%的牛群中发现了抗BRSV抗体。抗腺病毒I型3的特异性抗体出现在33.9%的血清中，相应地，在74.2%的牛群中出现。35.2%的奶牛或80.1%的牛群针对腺病毒II型8显示出阳性血清中和试验（SN）滴度。在2.3%的血清中或3.8%的牛群中检测到了IBR/IPV特异性抗体。在8.8%的奶牛中或22.6%的牛群中发现了抗衣原体抗体。在上述年份中，可观察到针对BRSV、腺病毒I型3、腺病毒II型8和衣原体的抗体存在显著差异，但针对PI - III和IBR/IPV则没有。通过卡方检验，发现西门塔尔牛、奥地利褐牛和荷斯坦弗里生牛在抗IBR/IPV和腺病毒II型8抗体方面存在显著差异。对于包含这三个品种之一的牛群的血清学结果，未观察到显著差异。
