Fig 6. Blinded evaluation of environmental fecal samples collected from CWD positive and negative herds.

Fig 6

Freshly deposited feces were collected from the ground at three different deer ranches. (A) Seeding activity of feces collected Ranch #1, with ~50% CWD prevalence. Twelve of 18 samples demonstrated seeding activity significantly higher than that of negative controls; * p<0.05, ** p<0.01, *** p<0.001, **** p<0.0001. (B) Ground-collected feces from Ranch #2 demonstrated significant seeding activity in 12 of 18 samples tested. Ranch #2 had CWD prevalence of about 30% from the pens where feces were primarily collected. (C) Ranch #3, a CWD negative herd over 100 miles from the nearest reported case of CWD in wild deer, showed no significant seeding activity in ground collected fecal samples as compared to negative controls.
