New,fast and efficient method for determining the antibiotic resistance for bacteria

摘要

A method of determining bacterial resistance or susceptibility by measuring the amount of antibiotic in urine or other bodily fluids after antibiotics have been administered. If the amount of antibiotic is above the thereapeutic level or minimum inhibitory concentration (MIC) it is inferred that the bacteria is not producing a beta lactamase and so is susceptible, whereas an absence or low level of antibiotic indicates bacterial resistance. The test may be used for monitoring antibiotic therapy, or after a standard antibiotic dose to screen for asymptomatic carriers of resistant bacteria. The test may be by lateral flow, particularly lateral flow immunochromatographic means, such a testing device is disclosed.
