Abstract

A lateral-flow immunoassay (LFT) was developed to detect bovine rotavirus in fecal samples. Using samples (n = 74) from diarrheic calves, a comparison of the LFT with a commercial latex agglutination test (LAT) and transmission electron microscopy (EM) was conducted. When EM was used as the reference method, initial studies of 29 samples indicated 70 and 80% sensitivities of the LFT and LAT, respectively, with both being 100% specific. When the LAT was the reference test, the LFT was 75% sensitive and 91% specific. Additional specimens (n = 45) were tested by the LFT and LAT alone, and results were identical for both methods.

摘要

开发了一种侧向流动免疫测定法(LFT)来检测粪便样本中的牛轮状病毒。使用腹泻小牛的样本(n = 74),对LFT与商业乳胶凝集试验(LAT)和透射电子显微镜(EM)进行了比较。当以EM作为参考方法时,对29个样本的初步研究表明,LFT和LAT的敏感性分别为70%和80%,两者的特异性均为100%。当以LAT作为参考试验时,LFT的敏感性为75%,特异性为91%。仅通过LFT和LAT对另外45个样本进行了检测,两种方法的结果相同。
