Figure 2From: Adhesion to and biofilm formation on IB3-1 bronchial cells by Stenotrophomonas maltophilia isolates from cystic fibrosis patientsSEM observation of 24 hours-biofilm formed byclinical isolate S. maltophilia OBGTC9 on IB3-1 cell monolayer. Scanning electron micrographs showing cell cluster morphology (microcolony) strongly suggestive of biofilm formation. Bacterial cells lose their outlines for the presence of extracellular matrix (arrows). Magnification: ×2.500 (Figure 2A), ×5.000 (Figure 2B).Back to article page
