摘要:   目的 分析伯氏疟原虫 ANKA株染色体分子核型 ,确定染色体的数目与大小。 方法 用脉冲凝胶电泳 (PFGE)方法对伯氏疟原虫 ANKA株进行核型分析。 结果与结论 伯氏疟原虫 ANKA株染色体共 14条 ,其大小为 0 .6~ 3 Mb。第 5~ 7和第 9~ 12条染色体在电泳中表现为共迁移。为利用多种特异性基因制作探针进行杂交 ,并对特异基因进行染色体定位提供参考。

Abstract:  Objective To analyze the molecular karyotypes of ANKA strain of Plasmodium berghei and demonstrate the size and number of chromosomes. Methods To isolate the genome DNA of P.berghei ANKA strain and analyze molecular karyotypes through CHEF-Ⅲ pulsed field gel electrophoresis (PFGE). Results The number of chromosomes was found to be 14, and their size ranged from 0.6 Mb to 3 Mb. Chromosomes number 5 to 7 and 9 to 12 appeared co-migrated in the gel. Conclusion PFGE technique is useful for analyzing the molecular karyotypes and may be also useful for further study to locate the special gene on chromosomes and carry out the genetic characters and mechanism of drug resistance.

Key words: pulsed field gel electrophoresis, ANKA strain of Plasmodium berghei, molecular karyotypes
