【摘要】 1985年4～9月于县苏县鼠疫疫源地通过监测发现,该疫源地动物鼠疫仍在广泛流行;但未发生人间鼠疫。黄鼠平均染菌率为1.51％,染菌率高峰为7月,单峰型;旱獭染菌率为0.81％。黄鼠间接血凝试验平均阳性率为13.74％,阳性率高峰在4月,低峰在7月,双峰型;牧犬血凝阳性率为10.25％;检验旱獭血清90份,其它动物10份,结果皆阴性。监测期间共检出鼠疫菌47株,其中检自黄鼠10株,黄鼠体外寄生物36株,旱獭1株。更多还原

【Abstract】 The plague surveillance made in the natural plague foci of Usu during the period April - September, 1985, revealed that epizootic plague occurred widely but that no human plague cases were found. The mean infection rate for the suslik was 1.51%, with one peak in July; and that for the marmot was 0.81%. The mean frequency of positive IHA test for the suslik was 13.74%, with high peak in April and low peak in July; and that for the farm dog was 10.25%. The exa mination of sera from 90 marmots and from 10 other animals led to negative re suits. A total of 47 strains of Y. pestis were isolated during the surveillance period, of these 10 were isolated from susliks, 36 from ectoparasites on susliks, and 1 from marmot.更多还原
