Method for testing drug susceptibility of tuberculosis bacteria, using indicator, and solid medium

摘要

A testing method for drug sensitivity of Mycobacterium tuberculosis , application of the indicator used in the method, solid medium and constant temperature heater and culture box used in the method are provided. The testing method for drug sensitivity of Mycobacterium tuberculosis comprises following steps: pretreating the provided specimen, and then adding liquid medium to conduct enrichment culturing, heating the solid medium to melt to prepare the solid medium in liquid state, mixing the specimen after enrichment culturing with the solid medium in liquid state, cooling to solid state, and preparing the solid drug sensitivity test specimen with drug sensitivity paper, culturing it for 5-15 days, observing the drug inhibiting ring by using an indicator to verify the drug sensitivity. The method costs less time for test and enables to perform drug sensitivity test of Mycobacterium tuberculosis in a safe and cost-effective manner.
