Abstract: Disclosed herein are a high-throughput continuous culture system and novel methodologies for the experimental evolution of natural and synthetic microbes using the continuous culture system. The microbial culture is exposed to a stress ramp function which is overlaid on top of a culture fitness function. The amount of stress applied to the culture is increased in response to increased fitness of the microbial culture.

Abstract: The present disclosure relates to compositions and methods for detection of single-stranded breaks (SSBs) in dsDNA, including in genomic DNA. Measurement of the precise location of SSB damage in DNA, e.g.

Abstract: Provided herein are pharmaceutical compositions and kits useful for sensitizing a microorganism or a population of microorganisms to a quinolone antibiotic. In a particular aspect, a carbon source and an electron acceptor can sensitize an antibiotic persistent microorganism to treatment with a fluoroquinolone antibiotic. Methods for sensitizing a microorganism to a quinolone antibiotic, reducing the density-dependent persistence (DDP) of an antibiotic resistant microorganism, and reducing the number of persistent cells in a population are also provided. Theses compositions and methods are useful in treating infections resulting from high-density bacterial cultures, such as pneumonia, genitourinary infections, biofilms, prosthetic graft infections, sepsis, and endovascular infections.
