I am trying to differentiate between Serratia marcescens and a gram pos. cocci
that I suspect is Staph epidermidis or S. aureus. I've placed the culture on
10% NaCl agar. I'll check the results later this morning. What is the best way
to seperate these organisms using the resources of a small college lab? Is my
first step in the right direction? Any suggestions would be appreciated.
Thanks. Terry
