细胞毒素相关蛋白（ｃｙｔｏｔｏｘｉｎａｓｓｏｃｉａｔｅｄｐｒｏｔｅｉｎ，ＣａｇＡ）和空泡形成毒素（ｖａｃｕｏｌａｔｉｎｇｃｙｔｏｔｏｘｉｎ，ＶａｃＡ）是幽门螺杆菌（Ｈｐ）相应的ＣａｇＡ，ＶａｃＡ基因编码产生的两种蛋白质，是Ｈｐ的重要致病因子，也作为Ｈｐ毒
Cytotoxin-associated protein (CagA) and vacuolating cytotoxin (VacA) are the corresponding CagA genes of Helicobacter pylori (Hp). The two proteins encoded by VacA gene are important virulence factors of Hp and are also used as Hp poison
