Fig. 3From: Highly variable effect of sonication to dislodge biofilm-embedded Staphylococcus epidermidis directly quantified by epifluorescence microscopy: an in vitro model studyThe effect of sonication is seen by comparing area covered by biofilm before and after sonication visualized by epifluorescence (a). To be able to quantify the covered area, pictures were dichotomized with help of a macro in the Fiji software (b). The resulting red area represents biofilmBack to article page
