The purpose of this investigation was to differentiate Staphylococcus aureus phage type 42D from Staphylococcus epidermidis.
The investigation involved four approaches to this differentiation. The first was a selective screening technique on specific media to point out physical and biochemical characteristics and to demonstrate the presence of specific enzymes. The second was a drug survey which was used to show basic susceptibility and resistance to ten different antibiotics. The third was ultra-violet irradiation which was used to discern susceptibility and resistance to the soft rays of this spectrum segment. The fourth was a chromatographic procedure using labeled carbon which demonstrated certain amino acids that were present and/or synthesized by these microorganisms, and showed carbon-14 incorporation by these microorganisms.
The differentiation therefore was based on the finding of similarities and differences. Since variation sometimes points to a genetic difference, the investigation also proposed to indicate some basic genetic similarities and differences between these two strains of staphylococci.
