RODAC results (reported in colony forming counts; CFU) by cage (n) and sampled area for group- or single-occupied mouse disposable IVCs at standard conditions (mean 72 °F [22.2 °C]) or thermoneutral conditions (TN, mean 82 °F [27.8 °C]) with diced cellulose bedding. Control values were 0 CFU for all time points.
