Psoroptic Cattle Scabies Research: An Evaluation

摘要

Psoroptic cattle scabies is a dermatitis that causes harmful itching, crusting, scurfing, and depilitation. Psoroptes ovis mites are the specific cause of common scabies in cattle. A major reason for the inadequacy of formerly successful eradication programs to meet the new situation in the cattle industry is that not enough is known about psoroptic scabies in cattle to permit the development of improved methods of diagnosis and more effective acaricides and equipment for administering them. The procedures for diagnosing active psoroptic scabies are generally efficient and accurate. The procedure for diagnosing latent infestations is inefficient and often inaccurate because both signs and lesions are usually minimal or absent. The management of cattle and the epidemiology of scabies are closely associated. A successful program to eradicate this disease would comprise: (1) early detection of disease or causative agent on cattle; (2) successful quarantine and treatment of infested cattle; and (3) tracing the origins of identified cases, instituting programs to eliminate the source, and tracing forward to facilitate early detection of new infestations.
