Hillman, Alison E., Ash, Amanda L., Lymbery, Alan J. & Thompson, R. C. Andrew, 2019, Anthropozoonotic significance, risk factors and spatial distribution of Giardia spp. infections in quenda (Isoodon obesulus) in the greater Perth region, Western Australia, International Journal for Parasitology: Parasites and Wildlife 9, pp. 42-48 : 45

3.1. Giardia spp . prevalence

On immunofluorescence microscopy, 99/284 of quenda were infected with Giardia spp . (34.9%; 95% CI 29.6–40.6%). Of these, sixtythree infections (64%) were successfully differentiated to species level by PCR and sequencing. All 63 quenda were infected with G. peramelis (apparent prevalence 22.2%; 95% CI 17.7–27.4%). One quenda was concurrently infected with G. duodenalis (apparent prevalence 0.4%; 95% CI 0.1–1.9%), and another quenda was concurrently infected with G. canis genotype D (apparent prevalence 0.4%; 95% CI 0.1–1.9) — both these quenda were trapped in urbanised environments.
