First Evidence of Sternal Wound Biofilm following Cardiac Surgery
Figure 5
Presence of staphylococci within the infected debrided wound tissues.
Representative confocal microscopy images of debrided tissue using immunofluorescence staining (debrided tissues was counterstained red with Phalloidin). Note large aggregates of staphylococci (intense green granular stain) colonizing the debrided tissues of infected sternal wound (lower panels), while tissues taken from a non-infected sternal wound during resternotomy (upper panels) show no colonization with staphylococci. Scale bar = 50 µm, 400x magnification. (SWI: sternal wound infection). Right panel is the zoom of the dashed boxed area in the left panel (scale bar = 20 µm).
