Abstract: Disposable plates for performing microbial antibiotic susceptibility testing with multiple channels can be inoculated with a microorganism and antimicrobial agent. The antimicrobial agent may be presented as a gradient of concentrations in the plate. The susceptibility testing plates are configured to allow viewing of microbial growth, and/or to be received in an automated instrument which analyzes same.

Abstract: A method and apparatus for performing microbial antibiotic susceptibility testing include disposable, multi-chambered susceptibility plates and an automated plate handler and image acquisition and processing instrument is described. The susceptibility plates are inoculated with a suitable microorganism such as bacteria, fungi, protozoa, algae or viruses and anti-microbial agent(s) are applied that the microorganism is exposed to at a variety of concentrations or a gradient of each anti-microbial agent. The plates are then placed in the instrument, which monitors and measures the growth or lack thereof of the microorganisms. This data is used to determine the susceptibility of the microorganism to the antibiotics. Such a system automates anti-microbial susceptibility testing using solid media and Carbo-Bauer standardized result reporting. The system provides a level of automation previously associated only with broth micro dilution testing, while retaining the advantages of the manual disk diffusion test.

The plates are then placed in the instrument, which monitors and measures the growth (or lack thereof) of the microorganisms. This data is used to determine the susceptibility of the microorganism to the antibiotics. Such a system automates antimicrobial susceptibility testing using solid media and Kirby-Bauer standardized result reporting. The system provides a level of automation previously associated only with broth microdilution testing, while retaining the advantages of the manual disk diffusion test.
