Mouse contact tracing protocol identifies and eliminates the outgrowth of NTCD-035 in the mouse colony

(a) Schematic of screening protocol established. (b) Total cages tested for NTCD-035 in the lab’s mouse breeding room. (c) Number of positive tests per week. ‘D’ denotes decontamination of rodent rooms. (d) C. difficile screen of sentinel mice from representative rooms and suites across campus. ‘#’ denotes the original rodent room identified with NTCD-035 positive mice. (e) C. difficile screen of sentinel mice over time. ‘New sentinels’ indicates the timepoint when naïve sentinel mice were introduced in the room without soiled bedding transfer from previous sentinel cage
