101). A client would like me to make a house call to check on
her 6-month-old house cat for a possible traumatic
skin injury. I am unable to go because I currently have a
dermatophyte infection, which I may be able to pass to the
cat. With which dermatophyte am I most likely infected?

103). A breeder brings in a litter of 3-month-old Persian kittens
with patchy alopecia, scaling, and hyperkeratosis
affecting mainly the head and face. I have just received culture
results confirming my suspicion of Microsporum
, canis. Money is no object, but I believe the therapy will be long-
term and there is poor prognosis for a cure. What
did I most likely observe that would lead me to these
conclusions?
(a) macronidia
(b) onychomycosis
(c) kerions
(d) dermatophytic pseudomycetomas

104) A couple of your classmates, who we will anonymously
refer to as Blair and Amy, discovered that they both
have localized areas of erythema and alopecia. These lesions
appear to be expanding in a circular (center to
periphery) fashion. Soon after discovering this horrific
condition, the duo noted that their dogs are afflicted with
similar lesions of alopecia, erythema, and crusts.
They mention to you that the dogs like to play around in the
back yard together. They (the dogs, not your
classmates) are often seen digging holes in the ground and then
rolling in the freshly churned earth.
You suspect that Blair and Amy have contracted a fungal
(dermatophyte) infection from the dogs and promptly
advise them to seek medical attention. In the mean time you
want to properly diagnose the dog's afflicting
agent. Which of the following tools should always be used to
diagnose a dermatophyte infection?
a) (CBC) complete blood Correct Answer c
