Abstract

Sequence analysis of the small subunit ribosomal DNA (SSU-rDNA) and elongation factor 1 alpha (ef1α) was performed on Giardia cysts isolated from faeces collected from a quenda (Isoodon obesulus) in the southwest of Western Australia. The SSU-rDNA and ef1α were sequenced in their entirety and correspondingly aligned with the published sequence information of other known species and genotypes of Giardia. Phylogenetic analysis of the SSU-rDNA and ef1α sequences identified the quenda isolate as a novel genotype of Giardia not previously reported. We believe that this quenda Giardia isolate constitutes a distinct species, which may be endemic within the Australian native fauna.
