本文用免疫印迹法测定了64例幽门螺杆菌(HP)相关性上消化道疾病患者血清中VacA和CagA抗体的阳性率。结果提示VacA和CagA阳性的毒力菌株为57.8％。建议在选择HP根治治疗时先进行HP毒力菌株的测定,以减少治疗费用及耐药菌株的产生。
In this paper, immunostaining was used to determine the positive rate of VacA and CagA antibodies in serum of 64 patients with Helicobacter pylori (HP) -related upper gastrointestinal diseases. The results suggest that 57.8% of VacA and CagA positive virulence strains. It is suggested that the determination of HP virulence strains should be conducted before selecting HP radical therapy to reduce the cost of treatment and the generation of resistant strains.
