Infrared light used to outwit sneaky, deadly bacteria

Researchers have devised a way to turn the tables on a sneaky strain of bacteria that can cause life-threatening diseases, based on a technique using infrared light.

Scientists at the University of Veterinary Medicine, Vienna said the technique lets them differentiate strains that can cause chronic infections and those that cannot.

"In principle, germs have two choices when they infect a host: attack or hide – in technical terms virulence or persistence. If they attack, they risk destroying the host and consequently themselves, whereas if they hide, they may be outcompeted by others. A detailed knowledge of the mechanisms of virulence and persistence and the way bacteria switch between them will help us to develop novel and more effective therapies," said Monika Ehling-Schulz, head of Grunert’s institute.

Results of the study have been published in the “Journal of Clinical Microbiology.”
