Bacteriostasis Experiment in Vitro of Se-enriched Herbal Medicine Compound Prescription to Escherichia Coli and Salmonella

The effect of bacteriostasis in vitro of Se-enriched herbal medicine compound prescription to escherichia coli and salmonella,which are the main pathogenesis strain of newborn pig diarrhea were studied with the method of plat double dilution in vitro bacteriostasis experiment.The results of the experiment indicates that,the minimal inhibititation concentration(MIC) of compound prescriptionⅠ,Ⅱ,Ⅲ to Escherichia are 0.04,0.02 and 0.04 g/mL respectively,and the MIC of compound prescriptionⅠ,Ⅱ,Ⅲ to salmonella are 0.04,0.02 and 0.02 g/mL respectively.In other words,the effect of bacteriostasis in vitro of compound prescriptionⅡto escherichia is better than that of the compound prescriptionⅠand Ⅲ,the effect of bacteriostasis in vitro of compound prescriptionⅡ,Ⅲ to salmonella is better than that of the compound prescriptionⅠ;the effect of bacteriostasis in vitro of compound prescription Ⅲ to escherichia is better than that of salmonella,and the effect of bacteriostasis in vitro of compound prescription Ⅰand Ⅱ to escherichia is close to that of salmonella.
