The surface area of brand new catheters with visible grooves (a) AFM image, scan area – 10 ×10 μm, colour scale 500 nm. (b) SEM image, horizontal side of the image – 8.3 μm

An AFM image (a) and SEM images (b, c) of the catheter surface – Staphylococcus spp. covered with biofilm. The scales are shown in the pictures

SEM images of the catheter: (a) formation of biofilm by connecting bacteria using exopolysaccharide skeleton (b) Staphylococcus spp. colonies covered with biofilm

SEM images of the catheter: (a) Typical colonies of bacteria from the Staphylococcus group. (b) No biofilm was detected at high magnification

An SEM image of the catheter. Bacteria can be seen in the morphology of Bacillus spp

An SEM image of the catheter: Morganella morganii, Acinetobacter baumannii, Staphylococcus epidermidis in a catheter tip culture, biofilm

An SEM image of the catheter: Staphylococcus haemoliticus in a catheter tip culture, biofilm

An SEM image of the catheter: Morganella morganii, Acinetobacter baumannii, Bacillus, Staphylococcus epidermidis in a catheter tip culture, biofilm
