Inhalation of very small numbers of living attenuated (BCG) organisms and their multiplication in guinea pigs results in the development of acquired resistance against subsequent airborne infection with virulent tubercle bacilli. Different strains of BCG have differing capacities to immunize by this means.
吸入极少量减毒活(卡介苗)微生物及其在豚鼠体内繁殖,会导致对随后强毒结核杆菌空气传播感染产生获得性抵抗力。不同卡介苗菌株通过这种方式免疫的能力不同。
