Figure 8: Identification and susceptibility testing of S. aureus. FL1-FL2-Dot Plots of bacteria cultivated from swabs. S. aureus was identified with a monoclonal anti protein A antibody and stained with DiBAC4(3) after incubation with oxacillin. Fluorescence 2 refers to the detection of protein A on the cell surface, increasing fluorescence 1 to the uptake of DiBAC4(3) due to oxacillin susceptibility. A) MRSA population from a swab from throat B) MSSA from a swab of the nose. C) Mixed culture with MRSA from nose D) Other species than S. aureus isolated from nose and oxacillin susceptible E) Other species than S. aureus, isolated from groin, oxacillin resistant.
