n number of isolates.

tcdA = toxin A.

tcdB = toxin B.

cdtA = binary toxin.

a One isolate from four different unexposed rooms; one isolate from one MRSA exposed room; two isolates each from two different C. difficile exposed rooms.

b Isolates from two different unexposed rooms.

c Isolate from one unexposed room.

d For one C. difficile exposed room, C. difficile could not be isolated from the patient’s specimen.

e One patient isolate from a C. difficile exposed room.

f One patient isolate from a C. difficile exposed room.
