Bacteriostatic Experiment of Twelve Species of Chinese Medicines and Its Compounds Against Escherichia Coli

Bacteriostatic experiment of twelve species of Chinese medicines and its compounds against escherichia coli K88 and hemoclatic escherichia coli had been made.The result showed that nine species of Chinese medicines had shown bacteriostasis against escherichia coli K88 and eleven species against hemoclastic escherichia coli. All compounds had shown bacteriostasis against escherichia coli Kgg and hemoclastic escherichia coli.The bacteriostatic effect of compuond 5 was superior to enrofloxacin's(1‰) against escherichia coli K88 (P0.05), and the bacteriostatic effect of compound 5 was superior to enrofloxacin's (1‰) against hemoclastic escherichia coli (P0.01 ).There was synergism between coptis root and enrofloxacin.
