| genetic characterization of isolates of giardia duodenalis by enzyme electrophoresis: implications for reproductive biology, population structure, taxonomy, and epidemiology. | the nature and extent of genetic variation in giardia was used to infer its mode of reproduction, population structure, taxonomy, and zoonotic potential. ninety-seven isolates of giardia duodenalis, from a defined area in western australia and throughout australia and overseas, were obtained from humans, cats, cattle, sheep, dogs, goat, beaver, and rats. enzyme electrophoresis revealed extensive genetic variation with 47 different zymodemes. the widespread occurrence of certain zymodemes and the ... | 1995 | 7776122 |
