Abstract;The effect of didecyl dimethyl ammonium chloride (DDAC) was assessed in the field on herds of calves, many of which were suffering from ringworm caused by Trichophyton verrucosum. The disinfectant was sprayed both on the calves and in their barns at Kagoshima University experimental farm once a week starting from November 2004 to January 2005. T. verrucosum was isolated from the environmental samples and the number and diameter of the ringworms in each individual calf were measured at the commencement of the study. To assess the improvement following disinfection, the measurements were taken again after six weeks of spraying. Among 43 calves present, 30 (70%) had ringworm lesions, mainly on the head and neck regions. In addition, T. verrucosum was isolated at a high rate from barn structures made up of iron material. Seven weeks following the beginning of the disinfection program, T. verrucosum was no longer isolated from the environmental samples, while the number of infected calves decreased from 30 to 18 (42%). In conclusion, it was proved that disinfection, using DDAC, of calves and their barns mainly constructed by iron material could be effective in the treatment and prevention of ringworm infection.
