摘要
用鼠疫菌强毒株883号实现了对人蚤灰旱獭株的鼠疫苗感染,其感染率,雌性为58％,雄性为51％。用大数量感染的人蚤灰旱獭株(分别为265只、102只)对健康幼獭叮咬,未出现鼠疫的传播,表明人蚤灰旱獭株感染蚤的鼠疫媒介能力甚低。
Human flea Pulex Irritans grey marmot (Marmota baibacina) strain was experimentally infected with virulent Y. pestis 883, with infection rates of 58% for female and 51% for male fleas. However, plague was not transmitted when healthy young Marmota baibacina were bitten by the infected fleas, indicating that human flea grey marmot strain played a minor role in the spread of plague.
