Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have established in mice the mechanism that detects and responds to the presence of bacteria in the womb - a discovery that opens up the possibility of new preventative treatments for diseases like pelvic in...

When the American Society for Microbiology (ASM) holds the 111th General Meeting in May 2011, participants will experience a redesigned conference with science and scientists at the forefront.
A major change for the medical microbiology community is the introduction of the Medical Microbiolog... Read More
High blood sugar levels can increase the risk of surgical site infections in patients having general surgery, researchers report.
Doctors have long been aware that people with diabetes are more prone to surgical infections, and the relationship between high blood sugar and increased risk of i... Read More
Better treatments and prevention for typhoid fever may emerge from a laboratory model that has just been developed for the disease. The model is based on transplanting human immune stem cells from umbilical cord blood into mice that are susceptible to infections.
The transplanted cells live a... Read More
Humans may have started out malaria-free then caught the disease from gorillas, an analysis of ape faeces suggests.
Malaria is one of our most devastating diseases. Apes carry related malaria-causing parasites, so biologists believed humans were already infected when they split from other gre... Read More
A study led by researchers at UC Davis has found how the bacteria Salmonella enterica -- a common cause of food poisoning -- exploits immune response in the human gut to enhance its own reproductive and transmission success. The strategy gives Salmonella a growth advantage over the beneficial b... Read More
Jim Collins, a College of Engineering professor of biomedical engineering and codirector of the Center for BioDynamics at Boston University, delivers the 2008 University Lecture, Biology by Design. He talks about his research at BU, including using noise to enhance sensory function and making an... Read More
Once Pseudomonas aeruginosa colonizes the lungs of a cystic fibrosis patient, it begins transforming itself from a squatter into a fully-invested resident, eventually establishing a chronic airway infection. A study just released by mBio tracked the gene expression patterns of P. aeruginosa dur... Read More
This episode: Discovery of (rather pretty) giant archaea!
Parasites such as Toxoplasma gondii invade host cells, replicate and then must exit to find new host cells to invade. Traveling outside their host cell exposes the parasites to environmental stresses that limit how long they can remain viable while searching for new host cells.
The researcher... Read More
Researchers from the Australia’s University of Ballarat have dispelled an urban myth by showing banknotes do not carry dangerous levels of bacteria.
But they found polymer banknotes, such as those used in Australia, carry the least quantity of contamination.
Australia's notes are manufactu... Read More
Global warming may have one minor but previously unknown benefit, scientists said this month: it may be cutting down cases of bubonic plague in the United States.
About 10 to 20 Americans catch plague each year, and 1 to 3 die of it, according to the Centers for Disease Control and Preventio... Read More
An examination of a portion of the tuberculosis genome that responds to stress has allowed Rice University bioengineers Oleg Igoshin and Abhinav Tiwari to zero in on a network of genes that may "switch" the disease into dormancy.
The bacteria that cause tuberculosis (TB), Mycobacterium tuberc... Read More
The list of ways for life to make a living keeps getting longer. There are the obvious: like turning light into chemical energy like plants do. Or eating plants like many animals do.
Then there are more specialist methods: for example, pairing the hydrogen produced by radioactive decay with s... Read More
There's been a lot of talk recently about NDM-1, a gene that gives many bacteria a weapon against carbapenems, an important class of antibiotics. Because many of these bacteria are already resistant to other classes of antibiotics, NDM-1 renders them immune to almost anything we throw at them. ... Read More
Every choice has its trade-offs, and while the advantages of many choices are easy to discern, other situations require closer analysis. In a paper just released by mBio, scientists have modeled the economic trade-offs involved in putting genes in an operon, and they’ve shed some light on why i... Read More
TWiV listeners have spent their valuable time writing comments about the podcast on iTunes, and it's a shame that most people don't see them. I'm putting them here as a way of thanking them for their time, and for listening. This i... Read More
