Fig. 4From: Highly variable effect of sonication to dislodge biofilm-embedded Staphylococcus epidermidis directly quantified by epifluorescence microscopy: an in vitro model studyThe figure illustrates variation seen in area covered by biofilm after sonication. Epifluorescence images show establishment of biofilm after 24-h incubation (before sonication (a), after sonication (b))Back to article page
