Effect of Relative Humidity on Growth of Clinically Isolated Three Candida spp.

Speciation of Candida species isolates from clinical specimen are described and its necessity is emphasized. A high water content in the substrate is almost a prerequisite for establishment of fungal growth and as a rule, dispersion spores are not produced unless the surrounding atmosphere has a relative humidity approaching 100%. In the present report it has been observed that C.albicans adversely affected by midrange relative humidity (60%) where as no such adversity was observed in C.parapsilosis and C.tropicalis with a slightest change of growth in the middle range of relative humidity.
