I am doing a science fair project on footware verses bacteria.  I am swabbing
the inside of different shoes out with a sterial applicator, then I put the
sample on the dishes, let them incubate for 48 hours .  I do know that (TSA)
can produce both positive and negative results.  But my problem is that I
can't seem to find out any imformation on these dishes.  I don't even know
what I am suppose to be looking for.
So, I figured if I know a little bit more about the petri dishes, what is in
them, it would help me.
Do you have any idea of what I should be looking for when it comes to
bacteria and footware?  Or what kind of bacteria these dishes can produce?  I
figure that it must be something different because of the different dishes.
Can you help me?
Thankyou,please write me back.

Hi - There are litterally thousands of species of bacteria that could grow 
on such plates. What were you trying to do?
