[Infection in man and dog with the mite, Cheyletiella yasguri Smiley].

The infection with the mite Cheyletiella yasguri Smiley in 3 dogs and 5 out of 6 persons exposed to infestation is reported. Two of the dogs appeared to have been infected during a stay in a kennel. The dogs presented with moderate itching and slight to massive floury squamation on the back. In the infected persons, excoriated papules were present on the body and the extremities.
