幽门螺杆菌 (helicobacter pylori,HP)与消化性溃疡的发生紧密相关 ,且其致病力与是否感染 HP毒力株有关 ,产生细胞毒素相关蛋白 A (cytotoxin as-sociated gene A ,Cag A)及细胞空泡毒素A(vacuolating cytotoxin A,Vac A)的HP毒力株是引起慢性胃炎及消化溃疡众多因素中的主要?
Helicobacter pylori (HP) is closely related to the occurrence of peptic ulcer, and its pathogenicity is related to whether it is infected with HP virulence strains to produce cytotoxin as-sociated gene A (Cag A) and The HP virulence strain of vacuolating cytotoxin A (Vac A) is the main cause of many chronic gastritis and peptic ulcer diseases.
