Abstract
En 中文
Large genomic deletions (LGDs) (6 to 63 kbp) were observed in isoniazid-resistant Mycobacterium tuberculosis mutants derived from four M. tuberculosis strains. These LGDs had no growth defect in vitro but could be defective in intracellular growth and showed various sensitivities toward oxidative stress despite lacking katG. The LGD regions comprise 74 genes, mostly of unknown function, that may be important for M. tuberculosis intracellular growth and protection against oxidative stress.
