Use of achromycin in the preparation of selective media for fungi

The isolation of pathogenic fungi from heavily contaminated material has always been difficult uptil now. Brain Heart Infusion medium containing 30 units of penicillin and 40 units of streptomycin has been found to be the best medium for the isolation of pathogenic fungi. Better results have been obtained by using Achromycin in place of penicillin and streptomycin.
