Effects of sub-inhibitory aztreonam lysine (AzLys) on Pseudomonas aeruginosa PA01 morphology and phage E79 recognition. Electron micrographs showing PA01 grown under normal conditions (A) without or (C) with E79, and (B) PA01 grown in the presence of 1.06 μg/mL AzLys (B) without or (D) with E79. Bacteria and phages were stained with 2% PTA and visualized by transmission electron microscopy at 4,400-fold (A,B) and 28,000-fold (C,D) magnification. Images are representative of at least 10 different bacterial cells per sample.
