Abstract:
In this study, our self-made micro-electrical impedance sensors and experimental apparatus were used to measure the impedance of bacteria-inoculated medium. Then the bacteria in the culture of all values obtained during the period were recorded into the trace impedance curve. Seeing the obvious difference in morphological change, we utilized the differed impedance curves in an attempt to estimate the morphological difference between the drug sensitivity of bacteria. The studies of clinical medicine for achieving rapid drug sensitivity test, automation and intelligentization of drug sensitivity are of practical significance.
