Latest Patents

Dongsheng Ding holds a patent for a device and method for automated antibiotic susceptibility testing of gram-negative bacteria. This patent describes an antibiotic susceptibility testing device that includes a temperature control unit, which features a constant temperature chamber, and a contactless conductivity-based measurement system. The device utilizes disposable glassy or PVC tubes as test vessels for antibiotic susceptibility testing (AST). During the AST assay, a specific liquid medium containing equal amounts of target bacterial cells and target antibiotics at varying concentrations is loaded into the test tubes. The samples are then incubated at a predetermined temperature within the device. The bacterial growth profile is monitored by measuring the differential values of conductivity of the liquid medium, which correlate with the proliferation of viable cells. The outcome indicates whether the target bacterial cells are inhibited by the test antibiotic, allowing users to determine the minimal inhibitory concentration (MIC) with ease.
