L-form generation in S. moniliformis by cell wall-active antibiotics. Growth of S. moniliformis on NA or NA/MSM (0.5 M sucrose) plates containing serum with or without 200 μg/ml phosphomycin (A) or ampicillin (B) at 30°C. Phase-contrast micrographs of S. moniliformis cells embedded in agar were taken from the plates (inside agar), or the cells were suspended in liquid NB (in liquid). (C)Streptobacillusmoniliformis cells were placed in Gene Frames on NA containing serum with 200 μg/ml ampicillin. Individual frames are extracted from Video S3 (Supporting Information). Numbers in the top right corner of each frame represent time (min) elapsed in the video.
