Mutation in an unannotated protein confers carbapenem resistance in Mycobacterium tuberculosis

P Kumar, A Kaushik, DT Bell, V Chauhan… - Antimicrobial agents …, 2017 - Am Soc Microbiol
ABSTRACT β-Lactams are the most widely used antibacterials. Among β-lactams,
carbapenems are considered the last line of defense against recalcitrant infections. As …

Revisiting the β-lactams for tuberculosis therapy with a compound-compound synthetic lethality approach

S Xiao, H Guo, WS Weiner, C Maddox… - Antimicrobial agents …, 2019 - Am Soc Microbiol
The suboptimal effectiveness of β-lactam antibiotics against Mycobacterium tuberculosis has
