If we can visualize a protein's shape, we can learn much more about how it functions and how we might block its activity. This was the guiding principle behind an NIH initiative launched 25 years ago to spur the discovery of HIV-related protein structures. Structures produced through the program... Read More
Julian Davies, University of British Columbia, discusses the future of antibiotics in his Society for General Microbiology Prize Medal Lecture at the Society for General Microbiology 2012 Spring Conference in Dublin, Ireland. Read More
Mathematics and Biology have a long history together. It goes back to early studies on epidemiology (such as John Snow‘s on cholera and the Broad Street pump), and includes Ross’s quantitative studies that show how malaria can be controlled by careful analysis of data. And, of course, there are ... Read More
The human vagina is a lively place, full of beneficial bacteria that discourage nasty microbes from invading. Now, new research finds this ecosystem is even more mysterious than previously realized.
Not only do women vary widely in what sorts of microbes call the vagina home, the study finds,... Read More
In order to survive in complex and interesting environments in the wild, bacteria have a whole arsenal of chemical products that they make within the cell. These chemicals are used for signalling, defence and communication between bacterial cells. One particular group of these chemicals is calle... Read More
Pared down genomes are the norm in symbiotic microbes, but how do non-symbionts get away with cutting out functions it would appear that they need? The authors of an Opinion piece in mBio this week explain their ideas about the matter. They say microbes that shed necessary functions may well be ... Read More
Dictyostelium discoideum is a soil-living amoeba. A group of 100,000 form a mound as big as a grain of sand.
The hereditary information is carried on six chromosomes with sizes ranging from 4 to 7 Mb resulting in a total of about 34 Mb of DNA, a multicopy 90 kb extrachromosomal element that h... Read More
How cool is that to be listening to you all reading my emails with Peter Sandman while I am stuck in traffic.
I loved the discussion and want to send a big thank you to Michael for joining in and giving us the missing perspective of what the NSABB ... Read More
Prosthogonimus macrorchis, a flatworm poultry parasite.
A digenetic trematode (family Prosthogonimidae) located in the oviduct and bursa fabricii of poultry in North America, particularly common in states bordering the Great Lakes. (http://www.medilexicon.com) Credit: Mr. Spike Walker

A recent test of packaged raw chicken products bought at grocery stores across the country found that roughly half of them were contaminated with the bacteria E. coli.
E. coli, which the study said was an indicator of fecal contamination, was found in 48 percent of 120 chicken products bought... Read More
From the Open University, a neat video highlighting seven amazing things microbes do. Read More
Researchers have determined that bacteria are present in the bladders of some healthy women, which discredits the common belief that normal urine is sterile. These findings were published in the April issue of the Journal of Clinical Microbiology by researchers at Loyola University Chicago Strit... Read More
Collaborative investigation efforts of state, local, and federal public health agencies indicate that a frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation is the likely source of this outbreak of Salmonella Bareilly infections. Nakaochi Scrape is tuna b... Read More
Once upon a time, tasters were employed by the well-to-do, in order to check that their food or drink wasn't poisonous. Today, there are electronic biosensors that can do more or less the same thing. Unfortunately, as was no doubt sometimes the case with the tasters, the biosensors can’t always ... Read More
Kim Ritchie fell into coral research as an undergraduate, got a Ph.D. in genetics and was doing post-doctoral research in Panama when she lost her funding. With the ideal training for biotech, however, she slipped right into a startup. But when the company went bankrupt, she jumped back into res... Read More
Learn about the bacteria, fungi and other micro-organisms that maintain human health.
The body contains 10 times more bacteria, fungi and other micro-organisms than human cells. Most of these species are harmless—although they can still cause illness if they wind up in the wrong place. In add... Read More
It’s an exciting time for ecologists who study microbes. DNA sequencing has grown so cheap and fast that they can run around identifying bacteria living just about anywhere they can reach with a cotton swab. Turns out, bacteria are everywhere, even in the cleanest houses, and scientists are star... Read More
