[Objective] To study the concentrations of three different kinds of antibiotics in rabbit bile, then evaluate their microbicidal potential, so as to present theoretical evidence and reference for choosing effective antibiotics for the prevention and therapy of hepatobiliary infection.

It illustrates microorganism control measures in bottle-packed pure drinking water production,introduces microorganism index control by ozone sterilization from the creation of ozone,its mixing with pure water,sterilization effect and its influential matters,which to give certain guidance for actual production.

The sterilization effect of high-intensity pulsed magnetic field (PMF) on bacteria was studied.

Using Escherichia coli as the object microorganism,the influence of different growth phase of Escherichia coli,magnetic field intensity,pulsed number of magnetic field and material temperature on sterilization effect was studied.

This paper discusses an experimental study for improving the germicidal efficacy of stabilized chlorine dioxide by orthogonal trial method.

Objective To know the germicidal efficacy and toxicity of a herb antibacterial lotion.

Objective To observe the effective of activating conditions on germicidal efficacy of chlorine dioxide.
