Differentiation of the pathogenic bacterium, Chlamydia trachomatis, from its non-infectious to infectious form is linked to the redox state of the organism.

Genome dilution limits cell growth by modulating the activities, rather than the concentrations, of RNA polymerases and ribosomes, and is accompanied by changes in proteome composition.

Degradation products of polysaccharides trigger partial population dispersal and alter cellular metabolism, shaping the marine biomass decomposition by foraging bacteria.

Klebsiella pneumoniae has specific repertoires of genes required for growth in urine and serum, highlighting new targets for antimicrobial treatments of this important pathogen.
