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 : 47

4.3. Geographical clustering of Giardia spp . infection risk

The area of substantially decreased odds of Giardia spp . infection in quenda in north-west Perth, identified on Kulldorff' s spatial scan statistic, correlates with the best available evidence (Howard et al., 2014) and our own subjective observations of an area of Perth with low density of quenda or interrupted presence of quenda over recent times, which may indicate lower levels of environmental contamination with viable G. peramelis cysts. However, the cluster of low infection risk may have been artificially strengthened by the edge effects of the coastline.
