Abstract:Objective:M. tuberculosis clonal DNA probes were prepared in order to establish a new method of the taxonomy and identification of mycobacteria on the level of gene.Three clonal fragments (Mt 24.2Kb,MT 43.5Kb,MT 53.0Kb) were radiolabelled by the probes.Their hybridizing results were quite similar:they all hybridized strongly with DNA from M.tuberculosis,cross-hybridized with DNA from M.bovis,M.bovis BCG,M.kansasii,M.avium,M.gastri,M.chelonei and M.gorconae,and did not hybridize with DNA from other 12 mycobacteria tested,E.coli and Nocardia asteroids.Therefore,the clonal DNA probe may become a useful tool for the identification of species.
Keywords:DNA probes  Clone  M  tuberculosis
