b'BIOFILMS IN THE LAB1 STPLACEKiril Kalenderski, University of NottinghamCLINICAL BIOMINERALIZED BIOFILM FORMED ON A URINARY CATHETER DEVICE A coloured environmental scanning electron microscope image (ESEM) of a biomineralized biofilm formed on a clinical urinary catheter device. Struvite minerals are coloured in orange, apatite minerals are coloured in yellow, and the biofilm structure is coloured in purple. Magnification- 500x.

MINERALS ENMESHED WITHIN A URINARY CATHETER BIOFILM Large struvite (yellow) and circular calcium carbonate (orange) minerals enmeshed within a biofilm (purple) formed on a urinary catheter (green). Calcite (calcium carbonate) and struvite (magnesium ammonium phosphate) are among the most common types of minerals associated with biofilms linked to symptomatic CAUTI manifestations.
