Figure 1From: Human plasma enhances the expression of Staphylococcal microbial surface components recognizing adhesive matrix molecules promoting biofilm formation and increases antimicrobial tolerance In VitroVisualization of staphylococcal biofilms grown in the presence of human plasma by CLSM and SEM. A-B) CLSM images biofilms of a methicillin-resistant (MRSA-3) and methicillin susceptible (UAMS-1) isolates of S. aureus grown overnight on coverslips in media supplemented with or without human plasma (10% Plasma). Biofilms were stained with a bacterial and a biofilm matrix stain to visualize the bacterial cells and extracellular polymeric matrix, respectively. Images were captured at 20X magnification. C-D) SEM analysis of biofilms of the clinical isolates listed above, following exposure to human plasma. Images were captured at 40,000X. Inlayed size bars represent 200Â nm.Back to article page
