Need info-staph and micrographs

    I'm a student at CSU Fresno.  We inoculated staph. aureus broth
onto baby pig skin samples and couldn't distinguish the bacteria in a
micrograph.  I believe the concentrations of bacteria were between 10^5
and 10^7 organisms/mL.  Instead, there were crater-like perferations on
the skin.  I'm aware that staph. is capable of producing proteinase, I
suspect they passed into the skin.  Any information you could send me
on this occurance or any web sources you could point me to which would
explain this would be great.  I'm specifically interested in whether
this is an accurate observation and if yes, how long does this take to
occur?  Our micrographs were allowed no more than 30 minutes when this
    Any help is appreciated. Thanks in advance,  David
