Figure 3From: Antibacterial activity of extracellular compounds produced by a Pseudomonas strain against methicillin-resistant Staphylococcus aureus (MRSA) strainsScanning electron microscopy images of the antibacterial effect of the F3d fraction (200 μg/ml) against the MRSA N315 strain at different times. A: negative control (2 h without antibiotic); B: F3d (30 min); C: F3d (2 h); D: F3d (4 h). When the bacteria were incubated with the F3d fraction for 2 and 4 h, morphological alterations were observed. No morphological cellular alterations were observed with 30 min incubation.Back to article page
