The titer of FI antigen was over 1:1280 by RIHA in 12 of 15 deceased rats and the serum titer of FI antibody was over 1:20 by IHA in 7 of 247 persons, 5 of 43 domestic cats and 3 of 80 domestic d...

• 7份死鼠同时进行RIHA和鼠疫菌分离培养,两种方法均为阳性,符合率100%25。人血清检测247份,猫血清43份,狗血清80份,阳性分别为7份、5份、3份。鼠疫菌对26种抗菌药物中的22种敏感。结论RIHA是动物间鼠疫最快速诊断方法,而IHA检测指示动物FI抗体是新疫点早期发现鼠疫疫情的线索之一。
