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.
