Physiologic Stresses Reveal a Salmonella Persister State and TA Family Toxins Modulate Tolerance to These Stresses

E Silva-Herzog, EM McDonald, AL Crooks… - PLoS …, 2015 - journals.plos.org

Bacterial persisters: formation, eradication, and experimental systems

S Helaine, E Kugelberg - Trends in microbiology, 2014 - cell.com
Persisters are multidrug-tolerant bacteria that could account for the relapse of infections. For
a long time, persisters have been assumed to be nonreplicating dormant bacteria, but the …

Persister cells: molecular mechanisms related to antibiotic tolerance

K Lewis - Antibiotic resistance, 2012 - Springer
It is a given that new antibiotics are needed to combat drug-resistant pathogens. However,
this is only a part of the need—we actually never had antibiotics capable of eradicating an …
