Figure 5 Effect of SRPP on H pylori; Minimum Inhibitory Concentration (MIC) (A) was established by serial dilution technique; B-D indicate the scanning electron microscopic pictures at 15 k magnification of control (B), SRPP (C) and amoxicillin (D) treated H pylori. Untreated control cultures indicate uniform rod shaped (a) H pylori cells. Amoxicillin treatment showed coccoid form (b), blebbing (c), fragmented (d) and lysed (e) cells. SRPP treatment in addition indicates cavity formation (f) with disrupted structures (g).
