3B–Incorrect.

The mite shown can be identified as Cheyletiella species by its prominent curved palpal claws adjacent to the mouthparts and the small combs rather than suckers at the end of its legs. By comparison, Sarcoptes scabiei does not have palpal claws and has stalks bearing suckers at the end of its legs.14 Although self-limiting, zoonotic infestations also develop in people exposed to dogs with sarcoptic mange. However, affected dogs more often develop an intense pruritus characterized by hyperkeratotic lesions on the lateral hocks, lateral elbows, and margins of the pinna.12
