Infections can come from a wide range of different ways such as shaking someone hand or touching something with a infection i like a hand towel and as some of you will know part of why in hospital the spread of infection so easy to happen people are together in hospital as such if infection s...

What kinds of microbes do you associate with hot springs? Maybe microbial mats? Thermus aquaticus and the discovery of Taq polymerase? Archaea, previously (and erroneously) thought to be strict extremophiles? Viruses may not be the first microbial subtype that springs to mind (pun intended) but ... Read More
News headlines highlighting an outbreak of a vaccine-preventable disease often leave readers shaking their heads. These diseases – measles, chickenpox, whooping cough – could have been prevented if only the infected children had been vaccinated. Right? Well, in the case of whooping cough, the si... Read More
This episode: Engineering bacteria to convert cellulose directly into useful biofuels and chemicals can be tricky!

We have some virology for you on the latest episode of the science show This Week in Evolution. Nels and I are joined by Kartik Chandran and Sara Sawyer who talk about their work showing how the filovirus receptor NPC1 controls susceptibility of bats to Ebolavirus infection. They have found that... Read More
This episode: Some bacteria seem to cause slime mold amoebas to carry around other bacteria for food!

Death from influenza virus in older people may be primarily caused by a damaging immune response to flu and not by the virus itself, new research suggests.
Ninety percent of the deaths attributed to flu each year worldwide occur in people aged 65 and older. To understand why older adults are ... Read More
The previous post mentioned the onset of antibiotic resistance as one of the scarier, if less sensationalist, outbreaks of our time. We generally discuss antibiotic resistance in medically relevant microbes (on this blog and in the news), where resistance means the ability of disease-causing mic... Read More
In episode #3 of the new science show This Week in Evolution, Nels and Vincent examine another important driver of evolution: recombination. The results of two papers in which the process is studied in finches and in yeast lead to the unexpected conclusion that recombination evolves more slowly ... Read More
How does a single-celled organism ‘know’ how to respond to its environmental conditions? Understanding microbial cell signaling is one way to determine how bacteria will react in a particular setting. In the past decade, researchers have revealed a significant role for cyclic-di-GMP in bacterial... Read More
Greg Caporaso was sifting through blog posts on microbe.net, which covers the microbiology of built environments, when a study idea sparked for him and colleagues Jeff Siegel, Scott Kelley and Rob Knight.
“It became clear to me that there was a lot of interesting work being done to understand... Read More
Plenty of people have weighed in on the question, 'Are Viruses Alive?' Here is my answer - different from all the others. Read More
On episode #2 of the new science show This Week in Evolution, Nels and Vincent talk about how a cellular enzyme contributes to the very high mutation rate of human immunodeficiency virus type 1.

The molecular order of events is important in virulence, and a new paper published in the Journal of Bacteriology looks at the order of events necessary for bacterial toxin delivery to a host cell. Specifically, the authors looked at the assembly of Shiga toxin, produced by Shigella dysenteriae ... Read More
Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... Read More
Zika virus RNA has been detected in New World monkeys from the Northeast region of Brazil. This finding suggests that primates may serve as a reservoir host for the virus, as occurs in Africa. Read More
One of the most dangerous places for an infection to occur is in the bloodstream. Septicemia, when microbes are present in the blood, not only allows bacteria access to other internal organs through the highway of our circulatory system, but also can cause a massive inflammatory response, leadin...

In this new video episode of Virus Watch, you'll see how the Zika virus particle is built, and how it binds to an antibody that blocks infection. All in gorgeous three dimensional views provided by recent structure studies. Read More
Project Premonition, a Microsoft Research project that uses drones to capture mosquitoes and analyze them for pathogens, preprint servers, and three mouse models for Zika virus induced birth defects are the topics of this episode hosted by the TWiumvirate and theirs guests Etha... Read More
Amidst the fear surrounding Zika virus, remember that there are over 100,000 children born each year with birth defects caused by infection with rubella virus.
Rubella virus is a member of the Togaviridae family, which also includes chikungunya virus. The genome is a 9.7 kilobase, positive st... Read More
