3.4. Associations between Giardia spp . infection and indicators of ill health

Faecal condition, skin condition and fur condition observations were available from all trapped quenda; subjective body condition was missing from one animal. There was no evidence of an association between Giardia spp . infection and any of these variables (p> 0.10; Table 3).

Forty-three out of 116 adult female quenda and 139/ 140 adult male quenda were included in testing the association between Giardia spp . infection and objective body condition. All excluded adult female quenda had pouch young, and the excluded adult male quenda did not have body weight recorded, which precluded calculation of their objective body condition scores. There was no evidence of an association between Giardia spp . infection and objective body condition in either adult female quenda (regression coefficient = −52.9, 95% CI -170.7 – 65.0; p = 0.37; adj. R 2 = −0.0043) or adult male quenda (regression coefficient = −10.8, 95% CI -97.2 – 75.6; p = 0.81; adj. R 2 = −0.0068) .
