Quantitative Studies of Total Lipids of Pathogenic Fungi

Department of Botany and Microbiology, University of Oklahoma, Norman, Oklahoma

ABSTRACT

Ten species of dermatophytes and four of the systemic fungi were assayed for total lipids, acetone-soluble fraction, and phospholipid content in different types of cultures. The yeast phase of each of the systemic fungi grown on solid medium exhibited a higher total lipid content than did the mycelial growth in liquid medium, either shake or still. Shake cultures, in all the fungi tested, produced the least lipids. The yeasts were consistently higher also in the acetone-soluble fraction. Histoplasma duboisii in the yeast phase and Microsporum gypseum produced the greatest amount of phospholipid, and Blastomyces dermatitidis in the yeast phase and M. canis produced the largest acetone-soluble fraction among the systemic fungi and dermatophytes, respectively.
