A clinical case of Cheyletiella infestation on a dog born and raised in Korea is reported. A three-year old female Whippet was hospitalized due to a multiple fracture and displacement of the left scapula caused by a recent car accident. The mite infestation was not noticed at the time of hospitalization. The dog underwent multiple operations involving internal fixation of the fractured scapula with wire and a plate, followed by extensive chemotherapy with antibiotics and prednisolone. After two months of hospitalization, a pruritic dermatitis near the left scapula developed. Multiple white dandruff-like flakes were seen on the hair coat, especially over the dorsal spine and neck, and the dog expressed increased pruritus by frequently licking and scratching the affected areas. Local dense accumulations of skin debris that became crusty were also observed. Microscopic examination of a skin scraping revealed a heavy infestation of cheyletiella yasguri, as identified by the presence of hoks of the palpi and the heart-shaped sensory organ on genu I. Immunosuppression elicited by the extensive administration of prednisolone was suspected for the initiation of the generalized mite infestation.
报告了一例在韩国出生并长大的犬感染犬蠕形螨的临床病例。一只三岁雌性惠比特犬因近期车祸导致左肩胛骨多处骨折和移位而住院。住院时未发现螨虫感染。这只狗接受了多次手术，包括用钢丝和钢板对骨折的肩胛骨进行内固定，随后用抗生素和泼尼松龙进行广泛的化疗。住院两个月后，左肩胛骨附近出现瘙痒性皮炎。在毛发上可见多个白色头皮屑样薄片，尤其是在背部脊柱和颈部，这只狗通过频繁舔舐和抓挠受影响区域表现出瘙痒加剧。还观察到局部有密集堆积的皮肤碎屑并结痂。对皮肤刮片进行显微镜检查发现，通过触须钩和第一膝节上的心形感觉器官的存在，确诊为重度感染犬蠕形螨。怀疑是由于大量使用泼尼松龙引起的免疫抑制导致了全身性螨虫感染的发生。
