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 ...

Considerable progress has been made in recent years in the structural and molecular biology of type IV secretion systems in Gram-negative bacteria. The latest advances have substantially improved our ...

The Type VI Secretion System (T6SS) is a sophisticated molecular apparatus found predominantly in Gram-negative bacteria. Structurally analogous to the contractile tail of bacteriophages, the T6SS ...

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 ...

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 ...

Researchers have discovered a molecular 'barcode' system used by disease-causing bacteria to distinguish between beneficial and toxic molecules. Researchers at McMaster University have discovered a ...

Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their ...

Cholera, a severe bacterial infection that causes diarrhea and kills if untreated, can be defeated with a diet high in protein, according to a new study from UC Riverside. Science X Daily and the ...

Scientists at the Max Planck Institute for Chemical Ecology report the discovery of at least six orders of endosymbiont Symbiodolus clandestinus, which lives inside insect cells. Using fluorescence in ...

Stabbing things, it turns out, is an enormously useful skill for bacteria. Some do it to deter insects. Some do it to attack bacterial competitors. Some, as I wrote about here two years ago, even seem ...
