Recent discovery of toxins that kill bacteria in novel ways
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, shows that the bacterial pathogen Pseudomonas aeruginosa, known to cause hospital-acquired infections such as pneumonia, secretes a toxin that has evolved to kill other species of bacteria.
The breakthrough, published in Molecular Cell, was achieved by Bullen following rigorous experimentation on common targets of toxins, such as protein and DNA molecules, before eventually testing the toxin against RNA.
This discovery breaks well-established precedents set by protein-targeting toxins secreted by other bacteria, such as those that cause cholera and diphtheria. Researchers say that this development holds great potential for future research that could eventually lead to new innovations that combat infection-causing bacteria.
