Bacteria were cultured for 24 h in M63B1 Glc and adjusted to an optical density (OD 600 nm) of 3. Cultures were centrifuged for 10 min at 7500 r.p.m. at 4 °C, and supernatants were filtered through ...

Scientists find that the unfolded end of a protein can kill E. coli-like bacteria selectively. The results may one day help scientists find new, more targeted ways to kill antibiotic-resistant ...

Bacterial toxins commonly translocate cytotoxic enzymes into cells using channel-forming subunits or domains as conduits. Here we demonstrate that the small cytotoxic endonuclease domain from the ...

Colicins are non-antibiotic antimicrobial proteins, produced by E. coli strains that kill or inhibit the growth of others. Several colicins are effective against key Enterohemorrhagic Escherichia coli ...

Professor Colin Kleanthous and his research group, together with colleagues in the chemistry department at the University of Oxford and at Birkbeck College, University of London, describe the snaking ...

San Diego, Calif. – When bacteria wage a turf war, some of the combatants have an extra weapon. Certain strains of the bacteria E. coli produce proteins that kill competing E. coli and other like ...
