GROWTH OF DERMATOPHYTES AT 4 DEGREES C AND 37 DEGREES C - RELATION OF THIS CHARACTER TO OTHERS

The ability of the genera Epidermophyton, Microsporon and Trichopyton to grow on some media at 4° C and 37° C was studied. It has been shown that specific differences exist among these fungi in the capability or rapidity of the growth at extreme temperatures. There is high positive correlation among perfect state production, isolation from the soil and growth at 4° C (group of characters A) and between pathogenicity and growth at 37° C (group of characters B). Between the groups A and B of characters exists a slighter negative correlation. Some prognosis about the five characters by certain species of dermatophytes may be given. © 1969 Dr. W. Junk N.V.
