Abstract:
Bdellovibrio bacteria BDF-H16 was isolated from the gut of Carassius auratus gibelio with Aeromonas sobria.Its shape was ob- served by light microscopy,phase-contrast microscopy,electron microscopy and some of its biological characteristics were also studied.It was demonstrated that BDF-H16 was an gram-negative bacterium and had a bacilliform or arc bacilliform shape with a flagellum at one end.Its size was mostly 0.2?m～0.5?m?0.8?m～1.2?m.It had a wide prey area and could lyse all tested gram-negative bacteria and some gram-positive bacteria.The best lysis conditions to Escherichia coli were 6.75?10~9 cfu/mL of prey bacteria concentration,pH7.0～7.5,28℃.It could grow in the solid culture added 0.85%～5.00% NaCl and was inhibited by enrofloxacin and norfloxacin.
