The notorious bacteria E. coli is best known for making people sick, but scientists have reprogrammed the microbe — which also comes in harmless varieties — to make it seek out and fight other disease-causing pathogens. The researchers’ report appears in the journal ACS Synthetic Biology and de... Read More
McMaster University researchers are about to launch Canada’s first tuberculosis (TB) vaccine clinical trial with a vaccine totally designed, manufactured and tested within McMaster.
"The exciting thing for McMaster is that this is translational research that has gone from the basic science wh... Read More
An ancient skin fungus that has been killing frogs, salamanders, and other amphibians may be hiding in invertebrates such as insects.
The skin fungus, Batrachochytrium dendrobatidis (Bd), also known as amphibian chytrid, got attention in 1993 when dead and dying frogs began turning up in Quee... Read More
Microbes living in Antarctica's saltiest lake swap huge chunks of genetic material as a means of surviving their harsh environment, a new study finds.
The single-celled organisms, called haloarchaea for their salt-loving ways, are biologically distinct from bacteria, algae and other tiny crea... Read More
The first of New York Times new Science Take series examines how a kind of bacteria can organize coordinated, wavelike attacks on prey using a stealth communication system.

A potentially pathogenic fungus has found a home living in extreme conditions in some of the most common household appliances, researchers have found. A new paper published in the British Mycological Society journal, Fungal Biology, published by Elsevier, shows that these sites make perfect habi... Read More
As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressur... Read More
A study conducted at the University of Strathclyde investigating the presence of Legionella in compost, has found that the bacteria exist in a significant number of commercial products.
The research, the first substantial analysis of Legionella in UK composts, suggests that the bacteria are a... Read More
Scientists regularly tap into biological systems to find solutions for human problems. Although they work with plants and viruses in the lab, bacteria have many advantages as a starting point. When programmed in certain ways, bacteria can store data, clean dangerous waste, produce film-like imag... Read More
When virologists Fouchier and Kawaoka were isolating avian influenza H5N1 viruses that could transmit among ferrets by aerosol, there was consternation from some quarters that such viruses might escape from the laboratory and cause a pandemic in humans. Part of the fear came from the fact that t... Read More
Serratia marcesens is a Gram-negative, rod-shaped bacterium that is commonly found in soil, water, on plants and in animals and thrives in damp conditions. This organism is well known for its production of the blood red pigment, prodigiosin. Production of prodigiosin can be influenced by several... Read More
The bug lives harmlessly in the noses of about a third of us. But it can turn rogue, causing skin infections—or worse. Heavy use of antibiotics since the middle of the last century has prompted the evolution of deadly superbug strains. Photograph by Martin Oeggerli, with support from School of L... Read More
For the majority of history, germs were an unknown entity. Their effects, from fermentation to illness were known, and yet no one exactly knew the cause. Then, nearly 350 years ago, Antoine van Leeuwenhoek, a one-time draper, looked through a flat lens made of ground glass and saw for the very f... Read More
Honey from bees kept in the Highlands is effective in treating infections, according to new research.
Glasgow University's School of Veterinary Medicine, which did the testing, said it could potentially be used for treating humans and animals.
Manuka honey, which is largely exported from N... Read More
How rare 'words' in bacterial genes boost protein production. Scientists routinely seek to reprogram bacteria to produce proteins for drugs, biofuels and more, but they have struggled to get those bugs to follow orders. But a hidden feature of the genetic code, it turns out, could get bugs with... Read More
Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

Whether inhabiting soil, fresh water, or marine ecosystems, bacteria are constantly facing the threat of numerous and effective predators such as protists, nematodes, or phages. To defend against such predation, bacteria have evolved a number of strategies, including getting larger in size, movi... Read More
This episode: Pathogen's CRISPR-Cas system (for defense against viruses) can be modified to change gene expression in mammals!
A sophisticated genetic analysis of Clostridium difficile cases is challenging the conventional wisdom that symptomatic patients are responsible for most transmission in hospitals.
Whole-genome sequencing of C. difficile isolates from more than 1,200 patients found that only 35% were related ... Read More
If the government shuts down in the absence of a budget agreement, the U.S. Centers for Disease Control and Prevention would be unable to support its seasonal influenza program that monitors the spread of flu, the Obama administration has announced.
The program is part of a series of initiati... Read More
