“…RelBE was demonstrated to be essential for M. tuberculosis persistence and upregulated in K. pneumoniae and S. aureus upon antibiotic challenge [14,23,24,34,35]. In E. coli, RelE overexpression enhances persistence towards all the antibiotics tested except mitomycin C [28].…”

“…Moreover, it has been indicated that MazEF is independent of (p)ppGpp [32,44]. In S. aureus, ΔmazF represses persistence in biofilms and some planktonic cultures, and mazEF is upregulated in both S. aureus and K. pneumoniae upon antibiotic treatments [24,34,35,52].…”

“…At present, in addition to drug resistance, S. aureus can also form biofilms and persisters on the surface of human tissues and organs or implants, causing chronic infections and non-healing. 5 The biofilm formed by S. aureus is composed of proteins, extracellular polysaccharides (EPS), and some small molecules (such as eDNA), which are conducive to their survival in extreme environments and can greatly limit the diffusion and penetration of commonly used antimicrobials, making them difficult to be completely cured. 6 Now, it was found that S. aureus can produce persisters under the influence of antimicrobials, and S. aureus biofilms also contain a large number of persisters, which are resistant to antimicrobials through complex dormancy mechanisms, resulting in repeated infections and difficulty to treat.…”

“…6 Now, it was found that S. aureus can produce persisters under the influence of antimicrobials, and S. aureus biofilms also contain a large number of persisters, which are resistant to antimicrobials through complex dormancy mechanisms, resulting in repeated infections and difficulty to treat. 5,7 Thus, now, it remains critical to explore new antimicrobials with an inhibitory effect on the biofilm formation and persisters of S. aureus. 8 However, the development of new antimicrobials often requires a long time, high investment costs, and huge risks.…”
