Treatment of Ringworm in Shelter Cats

Newbury, S., K. Moriello, et al. (2007). “Use of lime sulphur and itraconazole to treat shelter cats naturally infected with Microsporum canis in an annex facility: an open field trial.” Vet Dermatol 18(5): 324-31.

Dermatophytosis is the most common contagious skin disease of cats. It is often a concern in shelter situations since it is zoonotic and highly contagious. It is important to find an effective and rapid treatment protocol for cats with ringworm in shelters to expedite cure and adoption. This open clinical trial in a shelter enrolled 58 cats with confirmed Microsporum canis infection and 32 uninfected bonded pairs. The cats were treated with 21 days of oral itraconazole at 10 mg/kg and twice weekly lime sulphur rinses until cured. No hair coat clipping was performed. Fungal cultures were performed once weekly on all cats. Cats were considered cured with two consecutive negative cultures. No cats developed oral ulcerations as a result of grooming after lime sulphur treatment. No uninfected cats living in contact with infected cats developed dermatophytosis. The mean number of days of treatment required for cure was 18.4 (range 10-49 days). In this shelter, a combination of oral itraconazole and topical lime sulphur treatment was effective and safe.
