Superbugs on the rise in Canadian hospitals

Although infection control has been substantially ramped up in Canadian hospitals since the SARS crisis of 2003, the number of resistant bacterial infections post-SARS have multiplied even faster, a new Queen's University study shows.

Researchers find new path to antibiotics in dirt

A teaspoon of dirt contains an estimated 10,000 species of bacteria, but it's only one percent of these microbial bugs - the ones that can be grown easily in a lab - that have brought us antibiotics, anticancer agents and other useful drugs.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Bacteria can directly cause human blood and plasma to clot

Bacteria can directly cause human blood and plasma to clot - a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris. Their findings will be published online Nov. 2 in Nature Chemical Biology.
