J Med Microbiol 23: 83 -v 88, MORPHOLOGICAL ALTERATION OF STAPHYLOCOCCUS AUREUS, BA CILL US SUBTILIS AND BA CTEROIDES FRA GILIS BY LEVOFLOXACIN Mayumi Tanaka, Masako Otsuki and Takeshi Nishino Department Microbiology, Kyoto Pharmaceutical University, 5 Nakauchi-cho, Misasagi, Yamashina-ku, Kyoto 607, Japan The antibacterial effect levloxacin (LVFX, DR-3355) against Staphylococcus aureus, Bacillus subtilis and Bacteroides fragilis was examined by transmission electron microscopy from the viewpoint morphological alteration. When S. aureus was exposed to LVFX, abnormal division was observed at lower concentrations, and thickening the wall and lysis were observed at concentrations over the MIC. The B. subtilis became filamentous, swollen or lysed after treatment with LVFX, and some had degraded walls. In B. fragilis, filamentous, bleb-like structures, a degraded outer membrane and subsequent lysis were observed after exposure to LVFX.
