The four-week twice immunized hamsters acquired anti-MP in-fection capacity in local respiratory tract,as a result that swab culuturepositise was belove that of unimmunization group,and that only onehumster's lavage fluid culture was positive in immunization group.How-ever,unimmunization group positive rate of swabs and lavage fluid cul-ture was very high.This hinted that local respiratory tract's anti-MPinfection capacity was weak at the primary infection and the ability de-veloped gradually.4.The sIgA change in broncheal-lung lavage fluid.

而未免疫组咽拭子和支气管肺泡灌洗液MP分离培养的阳性均很高，说明在初次感染时，呼吸道局部防御清除MP的作用差，但随着时间的推移，其灌洗液培养的周次阳性率有下降趋势，MP培养的滴度亦随之降低，说明在感染以后随着时间的推移，呼吸道局部逐渐产生了防御、清除MP感染的作用。
