Persisters bacteria
Web9. jan 2024 · Scientists have been able to confirm what scientists have long thought, that persistence is very closely related to dormancy or slow growth. Analogies to bacterial persistence can therefore be found in nature, such as animals that go into hibernation, slowing metabolism during periods when their environment is not ideal for survival.Web11. júl 2024 · Persistent bacteremia caused by Staphylococcus aureus (SA), especially methicillin-resistant SA (MRSA), is a significant cause of morbidity and mortality. Despite susceptibility phenotypes in vitro, persistent MRSA strains fail to clear with appropriate anti-MRSA therapy during bacteremia in vivo.
