Mixed ectoparasitic dermatitis associated with Psoroptes spp. in a goat and its successful management

Abstract:

A 3-month-old female non-descript goat was presented with a history of progressive alopecia, severe pruritus, inappetence and marked emaciation. Clinical examination revealed generalized hair loss, hyperkeratosis and thick crusty lesions over the ears, dorsum and thigh regions. Deep skin scrapings examined microscopically revealed mites consistent with Psoroptes spp., characterized by long legs projecting beyond the body margin and segmented pedicels with terminal caruncles. Concurrent ectoparasitic infestation with Linognathus vituli, Haemaphysalis spp. and Ctenocephalides canis was also identified based on characteristic morphological features. Hematological evaluation indicated anemia, leukocytosis with eosinophilia, hypoproteinemia and hypoalbuminemia, while serum biochemistry revealed elevated aspartate aminotransferase levels. The animal was treated with ivermectin-based therapy along with antihistamines, vitamin supplementation and supportive care. Marked clinical improvement was observed and complete resolution of lesions with hair regrowth was evident after one month. The case highlights the clinical significance of psoroptic mange complicated by mixed ectoparasitic infestation in goats and emphasizes the importance of early diagnosis, comprehensive parasitological examination and integrated therapeutic management for successful recovery.
