ABSTRACT
Objective To evaluate the capacity of MTD method to distinguish between Myeobacterium tuberculosis and nontuberculosis mycobacteria.Methods Ten standard strains(including 1 H_(37)Rv strain and 9 nontuberculosis mycobacteria strains),94 clinical strains(including 48 Mycobacterium tuberculosis and 46 nontuberculosis mycobaeteria strains)and 40 sputum specimens were tested by MTD method(AMPLIFIED-MTI))and traditional methods.The results of these methods were compared.Results For all Myeobacterium tuberculosis and nontuberculosis mycobacteria strains,the agreement of MTD method and traditional method was 100%.And the positive detectable rate for sputum samples was 65% that was obviously higher than that for the direct smear(5/40),concentration smear(10/ 40)or culture(5/40).Conclusion MTD is a rapid test for identification of Mycobacterium tuberculosis and nontuberculosis mycobaeteria with high sensitivity and specificity.
