In order to isolate, study and efficiently treat a bacterial outbreak, it is vital to be able to grow, store and identify the particular strains of bacteria that cause the disease.
Second part of my thinly veiled excuse to research X-men and call it work. The first post can be found here. This is only meant to be a two-parter but I’ll see how I feel on Monday, and whether I can find any more X-men that are as amazing as bacteria.
As antibiotic resistance increases the search for new anti-bacterial treatments becomes more and more important. One way to design anti-bacterials is to find specific biochemical pathways that the bacteria require to survive, and develop drugs that block off these pathways.
Last week my husband needed some jars for cooking purposes. Tesco sell jars for somewhere around £3 each. However they also sell large jars full of sauerkraut for £1 each.
Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides.
Last month I had the privilege of being invited as a speaker for the Blogging Microbes event at the University of Nottingham. Hosted by Ivan Lafayette it was a great discussion of the role of blogs, twitter, and podcasts in communicating science, particularly microbiology, to a wider audience.
Cheese is a fascinating model for studying the intersection of human and microbial cultures. My project with Sissel Tolaas explores these connections through the process of making cheese using microbes sampled from the human body.
As #SciAmFood week draws to a close, we’ve heard a lot about the food we consume, from not getting enough to astronaut nutrition (and getting too much) to tricking your brain about what it’s getting.
When studying bacteria it is quite easy to get fascinated with them as a laboratory specimen while forgetting the huge impact they can have in real life societies.
Natural disasters such as earthquakes can have far-reaching effects beyond the damage caused on the day they occur. The 2010 earthquake in Haiti damaged the already limited sanitation systems leading to areas without adequate toilet and washing facilities; perfect for the spread of infection diseases.
Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations.
Microbes live in dense and diverse communities. There are billions of bacteria from thousands of species living together in your gut or in the soil.
This post was originally published in “Life of a Lab Rat” on Wednesday 3rd February 2010. Chameleon bacteria This is a picture of a small cyanobacteria under red light: And this is a picture of exactly the same organism under blue-green light: Some cyanobacteria have the ability to change their colour depending on external conditions.
I’ve recently been working on a new project with Ellie Harmon about dirt. Ellie hiked the Pacific Crest Trail last year, the 2,663 miles from the US border with Mexico to the border of Canada.
The bacteria that cause syphilis and Lyme Disease have something extraordinary in common: they manage to propel themselves through their environment in spite of the fact their tails are located inside their bodies.
With all the attention to the Ebola virus and other pathogens floating around in bodily fluids and the air, we may not be aware that the dirt beneath our feet is home to thousands of bacteria and other microorganisms.
A recently published study of a 30-pound martian meteorite found in Antarctica suggests the presence of indigenous carbon-rich material, ancient water erosion, and a number of tiny structures that resemble the sort of features that we see rock-eating microbes leaving in basaltic glasses here on Earth.
From the point of view of a micro-organism, the human body is a prime piece of real estate. For those bacteria and fungi that can avoid or fight off the immune systems, a human provides a whole range of moist, nutrient-filled little spaces in which to live.
Urea is a small molecule formed as proteins are broken down. It’s excreted in urine, but isn’t particularly toxic at low levels so it’s found in cells throughout the body.
We've never had an environment so rife with cheap caloric energy. The population-level rise in obesity is a natural response to this situation.
