Web1 hour ago · Persister cells are a subpopulation of transiently antibiotic tolerant bacteria, which are believed to be the main cause of relapsing bacterial infections. Due to the importance of persister cells in human infections, there is a need for new antibiotics that kill bacteria that display the dormant persister phenotype. However, high-throughput assays … WebLag phase is the period between the beginning of incubation and the point when the bacteria begin to actively reproduce and culture density slowly increases. During the lag phase, bacteria are adjusting to the new environment, metabolizing and synthesizing macromolecules, and increasing in number.
