Dermatophytosis is a potentially zoonotic superficial skin infection caused by keratinophilic fungi. Identification ofdermatophytes aids in understanding the epidemiology of infections and finding out better treatment modalities. The study aimed toidentify dermatophytes in dogs and compare the effectiveness of three different topical drugs for treating dermatophytosis. Molecularidentification of dermatophyte isolates obtained on culturing was done by restriction fragment length polymorphism of the ampliconobtained by polymerase chain reaction of the Internal Transcribed Spacer (ITS) region of the recombinant DNA. Thirty of the positivecases were divided into three groups, Group I was treated with shampoo containing 2% each of miconazole chlorhexidine, Group 2with shampoo containing 4% chlorhexidine, and the third group with lime sulphur dip. Clinical response and fungal colony countswere regularly monitored to assess improvement. Among a total of 30 dermatophyte isolates, 14 Microsporum canis, 8 Trichophytonrubrum, 6 M. gypseum, and 2 Epidermophyton floccosum isolates were identified. Increased occurrence of T. rubrum indicates frequenttransmission of dermatophytes from humans to dogs. Shampoo containing 4% chlorhexidine for an average duration of 99 days resultedin a faster cure, compared to the other topical preparations.
