Drug-induced changes in the plasma membrane of Microsporum canis.

Abstract
Commercial solutions of clotrimazole, tolnaftate and tolcyclate were tested for 12 h in cultures of M. canis. They induced modifications in particle distribution, a blebbing of particle-free areas and the appearance of lamellar figures on the plasma membrane of fungus cells. The 1st 2 changes in the plasma membrane might be ascribed to a modification of the spectrin-like meshwork, while the 3rd could be the result of a crystalline organization of membrane lipids.
