我国某些地区溶组织内阿米巴酶株群的分布

DISTRIBUTION OF ZYMODEMES OF ENTAMOEBA HISTOLYTICA FROM DIFFERENT AREAS OF CHINA

对来源于北京、天津、福建等地急性阿米巴痢疾患者和包囊携带者粪便中的5株溶组织内阿米巴的磷酸葡萄糖变位酶(PGM)、葡萄糖磷酸异构酶(GPI)、己糖激酶(HK)和L-苹果酸:辅酶Ⅱ氧化还原酶(ME)的同工酶谱进行比较分析。结果表明:5株溶组织内阿米巴均属于致病性的酶株群ⅩⅣ。提示,我国主要的致病性溶组织内阿米巴的酶株群是酶株群ⅩⅣ。

Using agarose gel electrophoresis, the electrophoretic patterns of four enzymes: ma-late NADP oxidoreducte.se (malic er.zyme) (ME), glucosephosphate isomerase (GPI), phosphogiucomutase (PGM) ar..d hexakinase (HK), were compared and analysed for five strains of Entamoeba histolytica, which had been obtained from patients with acute amebic dysentdry or asymptomatic cyst carrier in Beijing, Tianjin and Fujian Province. The results showed that the electrophoretic patterns of all the five strains of E. histolytica belong to pathogenic zymodeme. zymodeme XIV, which is suggested to be the main pathogenic zymodeme in our country.
