全世界每年有３００万死于结核病．ＤＮＡ检测已成为结核分枝杆菌诊断的主要技术．１９９８年结核分枝杆菌Ｈ３７Ｒｖ的全基因组序列被测定，并发现了候选毒型基因ｅｒｐ．这为人类认识结核分枝杆菌的致病分子机制和分子诊断开辟了前景．
Every year, 300 million people die from tuberculosis in the world. DNA testing has become the main technique for the diagnosis of Mycobacterium tuberculosis. The whole genome sequence of Mycobacterium tuberculosis H37Rv was tested in 1998 and the candidate gene erp was found. This opens up the prospect for human understanding of the molecular mechanism of molecular pathogenesis and molecular diagnosis of M. tuberculosis.
