如构建出突变体库，从中筛选出毒力减弱的副猪嗜血杆菌突变菌株，对研制出基因工程弱毒活疫苗具有重要意义。
So it's has great significance to construct the mutant storehouse and slecte the toxicity weak Hps mutant strain for developing the genetic engineering attenuated vaccine.
既有菌株中，未分型流感嗜血杆菌和溶血性嗜血杆菌在加重期和稳定期的痰菌浓度无差异；
Among preexisting strains, sputum concentrations of Nontypeable Haemophilus influenzae and Haemophilus haemolyticus were not different in exacerbation versus stable disease.
