ABSTRACT
This study evaluated the efficacy and safety of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Although several studies in dogs and cats with fungal dermatitis have found that oral administration of terbinafine is effective for controlling clinical signs, the topical form of terbinafine has rarely been studied in dogs and cats. Therefore, this study evaluated the efficacy of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Eight dogs infected with Microsporum spp. complicated with bacterial infection were enrolled in this study. These dogs were further blindly divided into Group 1 (no treatment, fourdogs) and group 2 (treated with medical shampoo with terbinafine/chlorhexidine, four dogs). Clinical improvement was evaluated using bacterial and fungal cultural evaluation combined with clinical evaluation. This study found that the medical shampoo has sufficient efficacy to treat varying degrees of dermatophytosis complicated with bacterial infection in dogs, although the speed of improvement differed according to the degree and type of infection. Our study also found that combined therapy using antifungal and antibacterial agents can improve clinical signs more effectively and rapidly, suggesting that concurrent bacterial infection plays a significant role in the development of dermatitis.
