They can cause a variety of symptoms, from cold-like symptoms such as runny nose or fever to more se... Read More

Innate immune defenses triggered by unsuspected mechanism

To the amazement of researchers in immunology and genetics, a previously unsuspected mechanism is activated in the presence of pathogens after only a few hours. "In the hours following an attack by bacteria, we observed the activation of thousand of genes in the cells of the innate immune system... Read More

You’re Probably Not Mostly Microbes

We are, supposedly, outnumbered in our own bodies. We play host to an extraordinary menagerie of bacteria and other microbes—the microbiome—and it’s frequently said that these teeming cells outnumber our own by ten to one. This 10:1 ratio crops up everywhere. It appears in scientific papers, blo... Read More

Whole-genome sequencing can help ID foodborne outbreaks

As we’ve seen in numerous cases in 2015, food contamination is a real issue for a number of different food types. Vegetable, meat, packaged, fresh – even pet food – we’ve seen too many examples of how bacteria can outsmart our best food safety practices. The Canadian government estimates 1 of ev... Read More

A Reprieve for Fungus-Battered Frogs

After a six-year effort, researchers on the Spanish island of Majorca have rid several groups of Majorcan midwife toads of the pathogen Batrachochytrium dendrobatidis — better known as chytrid fungus, or B.d. It’s the first time the disease, which is devastating amphibians worldwide, has been er... Read More

We breathe in more bacteria from our tap water than from our toilets

Microbiologists have wondered whether flushing our toilets might be spreading faecal bacteria into the air around our homes, but thankfully that doesn’t seem to be the case. Only 0.4 per cent of those in the air were traced back to the toilet bowl – far less than the almost 9 per cent that came ... Read More

Meet the young women leading the way in Ethiopia’s TB fight

In a post-Ebola world, these health-extension workers ... Read More

Does the Asian citrus psyllid’s bacteria spread citrus greening?

Helpful bacteria that live in the insect that transmits the pathogen associated with citrus greening disease may play a role in the pathogen’s spread.

A new study of the citrus greening bacterium’s effects on its insect vector, the Asian citrus psyllid, reveals multiple changes within the ins... Read More

Virologists, start your poliovirus destruction!
