作者采用随机扩增多态性DNA(RPAD)技术,试图发现不同阿米巴原虫分离株毒力的差异与种内和种间遗传变异性之间的相关性。从分离的11份溶组织内阿米巴、1份侵袭性阿米巴和2份莫斯可夫斯基内阿米巴(E.moshikovskii)无菌标本中,提取总DNA The authors used random amplified polymorphic DNA (RPAD) technology to try to find out the differences between the virulence of different strains of the amoeba and the intraspecific and interspecific genetic variability. From total 11 isolates of Entamoeba histolytica, 1 invasive amoeba and 2 sterile specimens of E.moshikovskii
