When Dr. Ian Crozier arrived in West Africa this past summer, he was stepping into the epicenter of the Ebola hot zone. The American doctor was working in the Ebola ward of a large, public hospital in Sierra Leone's dusty city of Kenema.
The trip nearly cost him his life. First came a fever, ... Read More
Whooping cough may be evolving to outsmart the currently used vaccine, say researchers.
Analysis of strains from 2012 shows the parts of the pertussis bacterium that the vaccine primes the immune system to recognise are changing.
It may have "serious consequences" in future outbreaks, UK r... Read More
A team of researchers led by Harvard geneticist George Church at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria...

Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa. Read More
The room is framed by a small square of transparent plastic, clamped to each of my cheeks and secured with a strap around my forehead. My breathing, growing ever more laboured, sounds like an astronaut’s; the erratic inhale and exhale of someone short on oxygen and trying not to panic. A paper m... Read More
Vultures relish rotting meat but how do they survive the deadly bugs that infest their food? It seems they opt for the probiotic approach, enlisting good bacteria to ward off the bad, microbiologists at Aarhus University in Denmark discovered in a study published in Nature Communications.
The... Read More
On his second trip to Brazil, Vincent joins Eurico to speak with four young virologists, Gustavo, Cintia, Tatiana, and Suellen, about their work and their prospects for careers in science.

Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... Read More
The general program for the 2015 American Society of Microbiology meeting in New Orleans is out, and registration is now open. The sessions look incredible, and I've listed them below as I imagine they might resonate with many of the readers of this blog. The bolded sessions look particularly in... Read More
I have just finished listening to TWiM 92 and it was very interesting, as always. It is a pleasure to listen to all of you discuss these fascinating topics.
At the end of this episode, you talk about probiotics because it w... Read More
The first microscopes, in the 1500s and 1600s, transformed glass panes that looked completely transparent into a universe teeming with bacteria, cells, pollen and intricate crystals. These visionary aids were the first devices to show people that there were cells within a drop of blood. Since th... Read More
A small team of researchers with Wageningen University in The Netherlands has found evidence that suggests that a type of virus that causes a species of caterpillar to climb higher up a plant, does so by causing a change to the victim's phototactic response. In their paper published in the journ... Read More
Breakthrough by scientists from UCLA, J. Craig Venter Institute and U. of Washington may be roadmap for study of other elusive bacteria.
One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bact... Read More
Here is my annual blogpost using #MicrobialSupremacy to wish all readers a very, very happy holiday season. I do this GFP and prodiosin, as well as luciferase! Enjoy a tiny bit of microbial art, relevant to the season? Read More
Cells have finger-like projections that they use to feel their surroundings. They can detect the chemical environment and they can 'feel' their physical surroundings using ultrasensitive sensors. New research from the Niels Bohr Institute shows how the finger-like structures, called filopodia ca... Read More
Tis the season for infections. And if you wind up with a prescription for penicillin or its relatives, you’re getting a gift that’ll give those unwelcome bacteria a double whammy.

One of America’s most famed natural wonders — the vibrant, prismatic hot springs of Yellowstone National Park — looked a lot different before tourists came along.
Most famously, the Morning Glory Pool used to be bright blue; it’s now more commonly known as “Fading Glory” or, even more accurat... Read More
Alex Moigboi was panicking. He was preparing to enter the Ebola ward wearing just a pair of gloves and a plastic gown over his scrubs. It was totally inadequate—like a firefighter entering a burning building wearing a pair of Ray-Bans—and Alex knew it. But he couldn’t find the rest of the protec... Read More
Different strains of Salmonella behave in different ways. Understanding how and why four closely related strains evolved to lead a more host adapted invasive life-style is at the heart of new research into the evolution of Salmonella microorganisms.
