Where in your community can you find the drug-resistant staph germs known as
MRSA? The surprising answer: They're closer than you may think.

(methicillin-resistant Staphylococcus aureus), it's easy to
forget there really are two MRSA epidemics going on at the same time.
By far the largest epidemic is going on inside hospitals and other health
care facilities. The staph bug causing these infections resists treatment with
a broad range of antibiotics. Because it...
The skin sample is placed on a slide with KOH solution and the solvent DMSO. This solution slowly dissolves the skin cells but not the fungus cells.
The fungus cells can then be seen with a microscope. Color stains may be used

Fungi are present in the skin samples.

fungal infection by the appearance of the rash and may not need to do a KOH
If the KOH preparation shows that you do not have a
fungal infection, other tests may be done to figure out the cause of
the skin problem.
