被动血球凝集试验(下称血凝)从70年代后普遗应用于鼠疫自然疫源地内动物病的调查,对及时发现动物间疫情以及了解其强度、范围和流行时间,发挥了重要作用。作为锡林郭勒高原布氏田鼠鼠疫疫源地主要宿主布氏田鼠Microrus bradti,其感染鼠疫后血凝抗体的动态规律,了解甚少,尚未见专门报道。为此,作了为期9个月的实验观察。 Passive haemagglutination test (hereinafter referred to as blood coagulation) from the 70’s universal application of plague natural foci within the animal disease investigation, timely detection of the outbreak of the animal and to understand its strength, scope and prevalence of time play an important role. Microrus bradti, a major host of the plague origin of Brandt’s voles in the Xilingol Plateau, has not been reported yet for its dynamic understanding of the hemolytic antibody after the plague was infected. To this end, made a 9-month experimental observation.
