Sensitivity testing antimicrobial susceptibility

TESTING FOR MICROBIAL SENSITIVITY TO ANTIMICROBIAL AGENTS Bacterial strains, even from the same species, may vary widely in sensitivity to antibiotics. Information about the antibiotic sensitivity of the infecting microorganism is important for appropriate drug selection. Various methods are used to assess susceptibility, including disk-diffusion, dilution test, and automated broth dilution. The results are either reported on a semi-quantitative scale i.e., resistant, intermediate, or susceptible) or in terms of the minimal inhibitory concentration (MIC). 

To determine what microorganism types are susceptible to the antimicrobial soap product, as well as the rates of microbial inactivation, in vitro tests should be conducted. These include time-kill kinetic evaluations, minimum inhibition concentration evaluations, and microbial sensitivity tests. However, in order to determine the actual effectiveness, human-use studies must be conducted. There are three common ways of evaluating antimicrobial hand soaps (1) the health care personnel handwash evaluation, (2) the modified Cade handwash procedure, and (3) the general-use handwash evaluation.
