在实验室保种的寄生虫,特别是培养的恶性疟原虫应当注意交叉污染。这一问题是英国寄生虫学会于1991年2月在爱丁堡召开的疟疾讨论会上提到的。最近许多工作均发现在恶性疟原虫种内有重要的基因变异。该种原虫野生群体的特点为存在着广泛基因多样性,包括从原发病人得到的分离物。从病人取得的分离物中,在遗传标志上还没有两 Parasites preserved in the laboratory, especially P. falciparum, should be aware of cross-contamination. The issue was raised by the British Society for Parasites at the Malaria Seminar held in Edinburgh in February 1991. Many recent work have found that there are important genetic variations in Plasmodium falciparum species. The protozoan wild population is characterized by the presence of a wide range of genetic diversity, including isolates from primary patients. There are no genetic markers in isolates obtained from patients
