> Giardia duodenalis is a pathogen that has been found in a variety of
> mammals, including humans, and consists of host-specific
> (assemblages C, D, E, F, and G) and zoonotic (assemblages A, B)
> genetic groups. Ferrets are popular pets, and they, like humans, are
> hosts to this pathogen. The genetic characteristics of the Giardia
> population in ferrets are unclear because only one ferret isolate
> has been genotyped. To develop a more complete picture of the
> genetic characteristics of the Giardia population in domestic
> ferrets two additional Giardia isolates, recovered independently
> from two ferrets suffering from intestinal or hepatic giardiasis,
> were analyzed genetically. The sequences of both isolates at three
> loci, small subunit ribosomal RNA (SSUrDNA, 292 bp), ss-giardin (734
> bp), and glutamate dehydrogenase (GDH, 713 bp) were identical to
> each other, but the sequences of triosephosphate isomerase locus
> (TPI, 512 bp) had five substitutions between isolates. Sequence
> homology and phylogenetic analyses at four loci identified both
> isolates as members of the assemblage A. Moreover, the sequences of
> SSUrDNA, ss-giardin, and GDH from both isolates were identical to
> those of the previous ferret isolate genotyped as assemblage A
> within the regions of overlap. The result obtained in the present
> study indicates that at least two genetically different types in
> assemblage A exist in domestic ferrets. In addition, there have been
> no reported human and animal isolates with the same sequence as
> those from ferret isolates at all four loci examined, suggesting
> that the present ferret isolates might be host-specific.
