Isoenzyme patterns of 32 isolates of Giardia duodenalis, obtained from 6 beavers and 11 humans from British Columbia, plus 15 other isolates were evaluated using thin-layer starch-gel electrophoresis. We attempted to use 12 enzymes; 9 gave reproducible and interpretable results. The isoenzyme patterns of the isolates were classified into 12 groups with 17 (53%) of the 32 isolates confined to 1 group. The other 11 groups each comprised only 1 or 2 isolates. There was no obvious correlation between clinical symptoms and isoenzyme patterns. Our findings suggest that beavers, like humans and gerbils are receptive to organisms with many different isoenzyme patterns.
从不列颠哥伦比亚省的6只海狸和11个人身上获取了32株十二指肠贾第虫分离株，另外还有15株分离株，利用薄层淀粉凝胶电泳对这些分离株的同工酶模式进行了评估。我们尝试使用12种酶；其中9种酶给出了可重复且可解释的结果。分离株的同工酶模式被分为12组，32株分离株中有17株（53%）局限于1组。其他11组每组仅包含1株或2株分离株。临床症状与同工酶模式之间没有明显的相关性。我们的研究结果表明，海狸与人类和沙鼠一样，容易感染具有多种不同同工酶模式的生物体。
