The fungicidal action of various therapeutic substances on two species of Aspergillus causing otomycosis was investigated. It was found that A. Niger was more resistant than A. Nidulans. The most effective fungicides were found to be 1% Methyl green and 50% alcohol or stronger. The results of this investigation indicate that a combination of methyl green and alcohol in the form of a 1% solution of methyl green in 50% alcohol would appear to be the best treatment for this type of otomycosis. It is suggested that a suitable wetting agent be added to facilitate contact between the therapeutic substance and the fungus.
