A patient has a staphylococcal infection of the blood; a septicemia – very serious and possibly deadly. As the
doctor, you would like to prescribe a relatively non-toxic and inexpensive drug out of the cephalosporin family.
However, if the patient harbors a strain of Staphylococcus that is resistant to a variety of antibiotics, you would
prefer to use vancomycin– which is highly effective against Staphylococcus.
Why is the cephalosporin drug preferred for use over the vancomycin?
