Characterization of the algC Gene Expression Pattern in the Multidrug Resistant Acinetobacter baumannii AIIMS 7 and Correlation with Biofilm Development on Abiotic Surface

Figure 6

(a)–(h) Visualization of biofilm augmentation by scanning electron microscopy. Electron micrographs (a, c, e, g) showing biofilms formed by algC clones after 24 h, at a gradient of magnifications (Bar = 2 μm, 5 μm, 10 μm, and 20 μm; absolute magnifications indicated as Kx in the very picture) as observed under a scanning electron microscope. algC clones can be seen clearly producing dense and robust biofilm as suggested by the thickness and integrity of the biofilm matrices, compared to the control biofilms by E. coli DH5α (lacking A. baumannii algC gene) at corresponding comparable magnifications (b, d, f, h).
