Phenotypes and genetic relatedness of invasive Haemophilus influenzae strains were evaluated from 1989 through 2001. Among 119 isolates, multidrug resistance decreased (from 50 to 0%), the level of H. influenzae serotype b (Hib) strains declined (from 81 to 16%), the level of noncapsulated strains rose (from 19 to 80%), and the first invasive H. influenzae serotype f strain was described. This study documents changes in invasive H. influenzae infections in Portugal, i.e., the emergence of non-type-b strains that are genetically diverse and unrelated to Hib.
1989年至2001年期间,对侵袭性流感嗜血杆菌菌株的表型和遗传相关性进行了评估。在119株分离株中,多重耐药性降低(从50%降至0%),b型流感嗜血杆菌(Hib)菌株水平下降(从81%降至16%),非荚膜菌株水平上升(从19%升至80%),并首次描述了侵袭性f型流感嗜血杆菌菌株。本研究记录了葡萄牙侵袭性流感嗜血杆菌感染的变化,即出现了遗传上不同且与Hib无关的非b型菌株。
