Scanning electron microscopic morphology of E. coli cells: a = after 6 h exposure to 0.04 mg/mL extract of Syzygium legatii (cells have rough or wrinkled surfaces, altered shape, and telescoping or invagination of some cells), b = after 12 h exposure to 0.04 mg/mL extract of Syzygium legatii (cells have rough surfaces, altered shape, and telescoping or invagination of some cells, protrusions on the surface), c = after 24 h exposure to 0.04 mg/mL extract of Syzygium legatii (cells are wrinkled, shrunken and rough with surface protrusions), d = after 6-h exposure to 0.04 mg/mL extract of Eugenia zeyheri (cells appear rough, twisted and wrinkled), e = after 12-h exposure to 0.04 mg/mL extract of Eugenia zeyheri (cells are wrinkled, shrunken, rough with cavitation, projections on the cell surface), f = after 24-h exposure to 0.04 mg/mL extract of Eugenia zeyheri (cells are wrinkled, shrunken, and rough
