The frequency of Bordetella bronchiseptica infection in Nebraska specific-pathogen-free (SPF) pigs was determined by serologic and bacteriologic cultural analysis. Serum samples from non-SPF herds were tested for comparison. A total of 1,282 of 1,397 (92%) of the SPF pigs tested had antibody to B bronchiseptica; 37 of 220 (17%) were culture-positive, and 67 of 4125 (1.6%) were considered suspicious for atrophic rhinitis during slaughter inspection. A higher percentage of the non-SPF pigs had titers to B bronchiseptica (642 of 659 pigs or 97% of the pigs tested). There was no relationship between the B bronchiseptica antibody titer, the isolation of B bronchiseptica, or the frequency of gross lesions of atrophic rhinitis from pigs within the herd. The serum agglutination test may be a more reliable procedure for determining the herd prevalence of B bronchiseptica than isolation of the organism by cultural methods.
通过血清学和细菌培养分析确定了内布拉斯加州无特定病原体（SPF）猪支气管败血波氏杆菌感染的频率。对非SPF猪群的血清样本进行检测以作比较。在检测的1397头SPF猪中，共有1282头（92%）对支气管败血波氏杆菌有抗体；220头中有37头（17%）培养呈阳性，4125头中有67头（1.6%）在屠宰检查时被认为疑似萎缩性鼻炎。非SPF猪中有更高比例的猪对支气管败血波氏杆菌有抗体效价（659头猪中的642头，即检测猪的97%）。猪群中猪的支气管败血波氏杆菌抗体效价、支气管败血波氏杆菌的分离情况或萎缩性鼻炎肉眼病变的频率之间没有关联。血清凝集试验在确定支气管败血波氏杆菌在猪群中的流行率方面可能比通过培养方法分离该病原体更可靠。
