Evaluation of blood oxidant/antioxidant balance in dogs with sarcoptic mange

The aim of this study was to investigate of oxidant/antioxidant balance in dogs with sarcoptic mange. The study materials consisted of totally 30 cross-breed male dogs; 15 with sarcoptic mange (study group) and 15 healthy as control. Blood samples for analyses were taken from control and study group. In study group, microscopic examination of dermal scrapings of 15 dogs revealed S. scabies. Lipid hydroperoxide level, total oxidant status and oxidative stress index in dogs with sarcoptic mange were higher (P < 0.01, P < 0.01 and P < 0.05, respectively) than the control. Otherwise; sulphydril levels in dogs with sarcoptic mange were lower (P < 0.05) than that of control. No significant differences were observed in total antioxidant capacity between groups. Our results suggest a possible relationship between oxidant/antioxidant imbalance and sarcoptic mange infestation in dogs.
