Abstract
- Enzyme polymorphism, analyzed by starch gel electrophoresis, was found to be zero for acid phosphatase, phosphoglucomutase, phosphoglucose isomerase, glucose 6-phosphate dehydrogenase, lactate dehydrogenase, malate dehydrogenase and malic enzyme, in one Brazilian and two Venezuelan strains of Schistosoma mansoni. 2. All loci studied were monomorphic within strains, but the isoenzymic patterns were, however, different among the strains. 3. Results suggest a drastic loss of the genetic variability usually found in natural populations.
摘要
- 通过淀粉凝胶电泳分析发现，在一株巴西曼氏血吸虫和两株委内瑞拉曼氏血吸虫中，酸性磷酸酶、磷酸葡萄糖变位酶、磷酸葡萄糖异构酶、葡萄糖6-磷酸脱氢酶、乳酸脱氢酶、苹果酸脱氢酶和苹果酸酶的酶多态性为零。2. 所研究的所有位点在菌株内均为单态，但同工酶模式在不同菌株间存在差异。3. 结果表明，通常在自然种群中发现的遗传变异性大幅丧失。
