Competition and antagonism are as much a part of microbial life as ours. The evolution of secretory systems that enable some bacteria to bombard their neighbors with toxins holds an obvious advantage ...

Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 ...

Antibiotic resistance is a growing concern. According to the CDC, more than 2.8 million antimicrobial-resistant infections occur each year. Now, a team of researchers has discovered a new group of ...

Researchers at McMaster University have discovered a previously unknown bacteria-killing toxin that could pave the way for a new generation of antibiotics. The study, led by John Whitney at the ...

Scientists at McMaster University have identified a toxin used by bacteria to kill other bacteria through a never-before-seen mechanism. The toxin is the first found to directly target RNA molecules ...

Only one thousandth of a milligram of the bacterial botulinum toxin is necessary to kill a living organism. The toxin unfolds its lethal effect by preventing the release of neurotransmitters at the ...

Scientists have discovered how a diarrhea-causing strain of bacteria uses 'molecular scissors' to cut open and destroy gut cells, leading to severe illness and sometimes death. Scientists at La Trobe ...

Life-forms with no brain are capable of some astounding things. It might sound like sci-fi nightmare fuel, but some bacteria can wage kamikaze chemical warfare. Pathogenic bacteria make us sick by ...

The Amazing Spider-Man may be science fiction, but a UA scientist’s discovery of a genetic link between spiders and bacteria is grounded in scientific fact. Matt Cordes, an assistant professor in ...
