      We recently have encountered strains of Staph aureus which have
multiple drug resistance but test in vitro as sensitive to oxacillin by
MICROSCAN, KIRBY-BAUER, and MRSA testing agar.  These strains seem to
exhibit tremendous BETA LACTAMSE PRODUCTION and produce clinical treatment
failures if cephalosporins or oxacillin are used.  HAVE YOU SEEN THIS?  

I have more details to relate for those who wish to converse on this
