Efficacy of Fluralaner in the Treatment of Sarcoptic Mange (Sarcoptes scabiei) in 12 Pet Rabbits

Sarcoptes scabiei var. cuniculi are cutaneous mites of companion rabbits. In rabbits, sarcoptic mange is characterized by intense pruritus, alopecia, erythema, scales, and crusts around the head, neck, trunk, feet, and genitals. The goal of this study was to evaluate the effectiveness of oral fluralaner in pet rabbits naturally infested by S scabiei var. cuniculi. Twelve privately owned pet rabbits with a definitive diagnosis of sarcoptic mange were included in the study if they had compatible clinical signs and positive superficial skin scrapings for S scabiei. Clinical and parasitological evaluations were performed on days 0, 7, 14, 21, 30, 60, and 90 after receiving a single oral dose of 25 mg/kg of fluralaner. On day 7, 5 of 12 rabbits had positive skin scrapings, while 8 of 12 had clinical signs (alopecia and erythema) still present. By day 14 none of the rabbits had positive skin scrapings and only 1 of 12 had persistent clinical signs. By day 21 none of the rabbit had positive skin scrapings nor had clinical signs. A reoccurrence of the clinical signs or positive skin scrapings was not observed for the duration of the study (day 90). A single oral dose of fluralaner was effective for the treatment of naturally occurring sarcoptic mange in rabbits over a 90-day period.

Abstract	Source
Sarcoptes scabiei var. cuniculi are cutaneous mites of companion rabbits. In rabbits, sarcoptic mange is characterized by intense pruritus, alopecia, erythema, scales, and crusts around the head, neck, trunk, feet, and genitals. The goal of this study was to evaluate the effectiveness of oral fluralaner in pet rabbits naturally infested by S scabiei var. cuniculi. Twelve privately owned pet rabbits with a definitive diagnosis of sarcoptic mange were included in the study if they had compatible clinical signs and positive superficial skin scrapings for S scabiei. Clinical and parasitological evaluations were performed on days 0, 7, 14, 21, 30, 60, and 90 after receiving a single oral dose of 25 mg/kg of fluralaner. On day 7, 5 of 12 rabbits had positive skin scrapings, while 8 of 12 had clinical signs (alopecia and erythema) still present. By day 14 none of the rabbits had positive skin scrapings and only 1 of 12 had persistent clinical signs. By day 21 none of the rabbit had positive skin scrapings nor had clinical signs. A reoccurrence of the clinical signs or positive skin scrapings was not observed for the duration of the study (day 90). A single oral dose of fluralaner was effective for the treatment of naturally occurring sarcoptic mange in rabbits over a 90-day period.
