Gas Plasma Pre-treatment Increases Antibiotic Sensitivity and Persister Eradication in Methicillin-Resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of serious nosocomial infections, and recurrent MRSA infections primarily result from the survival of persister cells after antibiotic treatment. Gas plasma, a novel source of ROS (reactive oxygen species) and RNS (reactive nitrogen species) generation, not only inactivates pathogenic microbes but also restore the sensitivity o...
متن کاملPersistent Persister Misperceptions
Persister cells survive antibiotic treatment due to their lack of metabolism, rather than through genetic change, as shown via four seminal experiments conducted by the discoverers of the phenotype (Hobby et al., 1942; Bigger, 1944). Unfortunately, over seven decades of persister cell research, the literature has been populated by misperceptions that do not withstand scrutiny. This opinion piec...
متن کاملCombatting bacterial persister cells.
Most bacterial cells lead lives of quiet desperation in biofilms, combatting stress; yet, their prevalence attests to their ability to alter gene regulation to cope with myriad insults. Since biofilm bacteria are faced with starvation and other environmental stress (e.g., antibiotics from competitors, oxidative stress from host immune systems), it behooves them to be able to ramp down their met...
متن کاملDevelopment of Persister-FACSeq: a method to massively parallelize quantification of persister physiology and its heterogeneity
Bacterial persisters are thought to underlie the relapse of chronic infections. Knowledge of persister physiology would illuminate avenues for therapeutic intervention; however, such knowledge has remained elusive because persisters have yet to be segregated from other cell types to sufficient purity. This technical hurdle has stymied progress toward understanding persistence. Here we developed...
متن کاملBacterial persister cell formation and dormancy.
Bacterial cells may escape the effects of antibiotics without undergoing genetic change; these cells are known as persisters. Unlike resistant cells that grow in the presence of antibiotics, persister cells do not grow in the presence of antibiotics. These persister cells are a small fraction of exponentially growing cells (due to carryover from the inoculum) but become a significant fraction i...
