Microbial secretion systems are at the core of bacterial physiology, facilitating processes such as protein export, ...

Bacterial interaction with plants and animals, symbiotic or pathogenic, involves the transfer to host cells and tissues of a range of bacterial proteins whose biochemical activities are key to ...

Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and ...

Bacteria have complex molecular machines that help them drive disease. Scientists can now leverage these machines to treat disease instead. We primarily work with nanobodies, although we have shown ...

Swallow the wrong microbe, and you might end up in the hospital with a needle or two in your arm — and plenty of itty-bitty bacterial needles poking at you from the inside. That’s because many ...

Researchers at McMaster University have discovered a molecular "barcode" system used by disease-causing bacteria to distinguish between beneficial and toxic molecules. Published in the Proceedings of ...
