Cecropin A (CA) fungicidal properties were explored. Nongerminated and
germinated Aspergillus spp. and Fusarium spp. conidia were treated wi
th CA. CA achieved complete lethality at less than or equal to 25 mu M
(99 mu g/ml) for germinating, but not nongerminating, conidia of Aspe
rgillus spp. CA achieved total lethality for nongerminated and germina
ting conidia of Fusarium spp at 1.5 mu M (6 mu g/ml). MIC and minimal
lethal concentration assays in buffered RPMI medium gave similar resul
ts.
