Well, not exactly, but two female mice that were bred by backcrossing a
transgenic line onto B10.A developed a dermatitis which led to sloughing
off of the skin.  Pathological exam revealed no ectoparasites.  I learned
from reading the strain lists on the web at Jackson that C57 mice
have a low frequency of developing a skin irritation which leads to
self-mutilation similar to what I saw in my colony.
