Trichoderma harzianum and T. viride Crude Extracts Effect on Species of Trichophyton which Caused Skin Human Disease

Two Trichoderma species (T.harzianum and T.viride) were used in this study, in which the crude extracts of these fungi were extracted and tested (with compared ketoconazole) at the concentrations 0.1, 0.5, 1 and 2 mg/ml against different species of the human pathogenic fungi Trichophyton, the results showed a huge inhibition activities of these extracts against the tested fungi with some differences in the ratio of inhibition also when compared with ketoconazole, but the results showed that the crude extract of T.harzianum showed the greatest inhibiting activities toward the tested fungi especially at the concentrations 1 and 2 mg/ml, in which the ratio of inhibition reached 100% at the concentration of 2mg/ml against all the tested fungi, and this extract must be take many test to could be used as one of the most active and potent biological control means against the human pathogenic fungi.
