3연령 잡종편이 소양감, 탈모의 증상으로 내원하였다. 신체검사에서 전신적으로 발적, 구진, 탈모, 비듬 그리고 가피의 병변이 관찰되었다. 전반적인 피부검사결과 개선충, Staphylococcus spp과 Malassezia spp의 혼합 감염으로 진단되었다. Selamectin 6 mg/kg을 2주간격으로 2회 경부피부에 적용하였다. 그리고 한 달간 구균과 Malassezia 치료를 위해 amoxicillin trihydrate/clavulanate pattassium과 ketoconazole 10 mg/kg을 경구투여하고 5% chlorhexidine 샴푸를 주2회 실시하였다. 첫 치료 후 7,14,21 그리고 28일에 피부를 재검사 하였을 때 개선충은 관찰되지 않았으며 피부 증상은 현저하게 개선되었다. 피모는 거의 정상으로 회복되었으며 Staphylococcus와 Malassezia spp는 거의 관찰되지 않았다. 그러므로 이 치료절차에 따른 selamectin 적용은 개선충이 감염된 개에서 매우 효과적이라고 사료된다.
A 3-year-old, male, mongrel dog was presented with pruritus, alopecia to the Veterinary medical Teaching Hospital, College of Veterinary Medicine of Kyungpook National University. On physical examination, generalized erythema, papules, scales and crusts were observed. The canine scabies infestation was diagnosed by deep skin scraping and Malassezia spp. and Staphylococcus spp. were found on skin cytology. He was treated with selamectin at 6 mg/kg applied to the skin in a single spot every two weeks for one month in order to investigate the effect of selamectin on canine scabies and was treated with amoxicillin trihydrate/clavulanate pattassium, ketoconazole and chlorhexidine shampoo for Malassezia sup. and Staphylococcus spp. simultaneously. When he was rechecked after 7, 14, 21, and 28 days after the first application of selamectin, scabies werent seen. The dermatological signs including pruritus, papules, scales, and crusts were remarkably resolved at 14 days. The alopecia was almost disappeared and few Malassezia spp. and Staphylococcus spp. were seen after 28 days. The efficacy of selamectin by this protocol is excellent in the dog infestated canine scabies.
