| prevalence of cryptosporidium and giardia species in animals in irrigation catchments in the southwest of australia. | screening of 445 animal faecal samples in irrigation catchments in western australia (wa) was conducted to identify the prevalence of cryptosporidium and giardia species. of the samples positive for giardia duodenalis, 30.7% (12/36) were the zoonotic assemblage a, while approximately 13% (4/30) of cryptosporidium positives were zoonotic. this is the first finding of giardia assemblage a in native marsupials and birds and indicates that marsupials and possibly birds may potentially be a reservoir ... | 2008 | 18068157 |
| 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 |
