Scanning electron micrographs of P. aeruginosa incubated with cementoin, elafin, pre-elafin/trappin-2 or magainin 2. P. aeruginosa (~1 × 107 in 500 μL) were incubated 2 h with the indicated peptides before being processed for scanning electron microscopy as described in Methods. CNT; control performed in the absence of peptides, PE; pre-elafin/trappin-2, Cem; cementoin, Ela; elafin, Mag; magainin 2. White arrows point to pore-like structures and white arrowheads to ghost bacterial cells.
