Abstract:
Only 25 of 77 dermatophytic isolates caused dermatophyte identification medium (DIM) to turn purple after incubation at the recommended temperature (37 degrees C); the accuracy of the results was improved at 30 degrees C (71 of 77 isolates yielded positive results). Many dimorphic pathogenic fungi also tested positive at both incubation temperatures. Thus, DIM has limited usefulness for presumptive identification of dermatophytes.
