  1. Apparent prevalence (proportion of sample infected) of chronic wasting disease infection among adult mule deer (Odocoileus hemionus) from the Table Mesa herd near Boulder, Colorado, USA. Results apportioned by PRNP codon 225 genotype (serine [S] or phenylalanine [F]) and sex. Prevalence in 2018–2019 did not differ between sexes, even among 225SS deer (two-tailed Fisher’s exact tests P ≥ 0.468). Prevalence estimated from immunohistochemistry of rectal mucosa biopsies including ≥3 lymphoid follicles and reported with 95% binomial confidence limits (bCL). Data from 2005 are included for comparison5. Of the 100 deer sampled in 2018–2019, nine with inadequate biopsies, one 225FF, and one of an undetermined genotype are excluded from this tabular summary.
