All of the effects of antimicrobial agents against microbes, including the delineation of microbial resistance, are based upon the results of in vitro susceptibility testing.
There is now a growing debate whether in vitro susceptibility testing should be performed for all Bacteroides isolates to guide antimicrobial therapy.
In vitro susceptibility testing for fluconazole (powder provided by Pfizer BV, Capelle a/d IJssel, The Netherlands) was performed by the broth microdilution
The factor that converts antimicrobial therapy from "empiric" to "rational" is in vitro susceptibility testing and reporting.
In vitro susceptibility testing with the AST-N032 Vitek 2 card (bioMerieux) showed that the organism was resistant to ampicillin, ticarcillin, piperacillin, and aminoglycosides.

Clinical and Laboratory Standards Institute (CLSI) recently published an updated document, Development of In Vitro Susceptibility Testing Criteria and Quality Control Parameters for Veterinary Antimicrobial Agents; Approved Guideline--Third Edition (M37-A3), which offers guidance for developing agar disk diffusion zones of inhibition, dilution MIC breakpoints, and quality control limits for antimicrobial susceptibility testing of aerobic bacteria isolated from animals.
More studies are needed to investigate the inter-method agreement of tigecycline in vitro susceptibility testing so that breakpoints and disc diffusion guidelines can be formulated for Acinetobacter spp.
The interpretive standards for in vitro susceptibility testing of mycobacteria pose another problem because new and more potent drugs are available to treat diseases such as tuberculosis, according to Dr.
doricum will be valuable so that in vitro susceptibility testing can be correlated with clinical responses, eventually enabling development of guidelines for therapy.
In this instance, trimethoprim/ sulfamethoxazole and doxycycline were chosen because of availability of oral formulations, in vitro susceptibility testing results, and affordability given the patient's lack of medical insurance.
