A. Surface adhesion to polystyrene microtiter plates by A. baumannii SMAL clone. Black bars bacterial cultures grown in LB medium; light grey bars LB1/4 medium; white bars M9Glu/sup; dark grey bars M9Suc/sup. B. Binding of Calcofluor to A. baumannii SMAL clone grown in solid media. C. Inhibition of A. baumannii biofilm formation by cellulase treatment: circles, M9Glu/sup medium; diamonds, M9Suc/sup medium; squares, LB1/4 medium. The horizontal dotted line indicates the 50% inhibition mark. IC50's values are indicated by vertical dotted lines.
