Transmission electron microscopic (TEM) images (11.000X.) of Staphylococcus. pasteuri (Gram-positive) and Salmonella Typhimurium (Gram-negative) as affected by 20 µg/mL of MPP, gentamicin (Gent) and combination of MPP + Gent as compared to control (Cont). Two images were taken at the same magnification power for each treatment. The small letters of a, b, c, and d refer to normal bacterial cells, cell components lysis, cell wall destroy and completely deformed bacterial cells, respectively
