- What
are you looking for in a direct Gram stain or in the gross appearance of
exudate, which would be suggestive of actinomycetes or fungi?

discuss skin infections relating to the following:

culture is still the most sensitive method of
diagnosing cutaneous infections, what media should be
used?
- What
organism and infection would be treated empirically
with penicillin and would not require a susceptibility
test?
- Discuss
the following types of cutaneous infections.
