Fig. 4

a Representative image showing the random 25 regions (white square dots) chosen on the surface of wing to measure the adhesion propensity of the P. aeruginosa strains. b Number of points on the surface of coverslip and wing to which PAO1 and ATCC 9027 showed adhesion. c Adhesion force exerted by ATCC 9027 and PAO1 on coverslip and wing was represented using Box–Whisker plot. Box represents the distribution range of values. Dark line inside the box represents 50% values. Thin line in the box represents average value. Square dot represents median value and, the bars represent standard deviation. d Representative force-distance curves of PAO1 and ATCC 9027 on coverslip and wing surface. Red line represents the probe-approach and blue line represents the probe-retraction
