Abstract:

Tuberculosis (TB) is one of the major causes of death for infectious diseases. The emergence of drug-resistant TB increased the difficulty for TB prevention and control. As a new anti-tuberculosis drug, Delamanid performs its bactericidal action by inhibiting the synthesis of mycolic acid of Mycobacterium tuberculosis cell wall, and has good tolerance and safety. However, within a year of clinical application, drug resistance against Delamanid has already been observed. This paper reviewed the clinical application, antibacterial mechanism, drug susceptibility test technologies, epidemiological investigation and molecular mechanism of drug resistance of Delamanid,in order to promote clinical understanding of Delamanid and provide more reference for rational treatment of drug-resistant tuberculosis patients.

Key words: Mycobacterium, tuberculosis, Delamanid, Microbial sensitivity test, Drug resistance, Gene
