High-molecular-weight proteins of Haemophilus influenzae mediate attachment to epithelial cells. Previous reports describe several allelic versions of hmwA genes that have different adherence properties. Here we report three new alleles of hmwA (hmwA from strain AAr96, hmwA from strain AAr105, and hmwA from strain G822), demonstrating the high degree of DNA variation of these genes among different strains.
流感嗜血杆菌的高分子量蛋白介导其与上皮细胞的附着。先前的报道描述了几种具有不同黏附特性的hmwA基因的等位基因变体。在此,我们报告了hmwA的三个新等位基因(来自菌株AAr96的hmwA、来自菌株AAr105的hmwA和来自菌株G822的hmwA),证明了这些基因在不同菌株间存在高度的DNA变异。
