title: [Analysis on karyotypes of ANKA strain of Plasmodium berghei].
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.
  
  
  CONCLUSIONS
  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.
