How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa? A team of researchers headed by Dr. Friedrich Frischknecht, head of a research group at ... Read More
Frederick C. Neidhardt, F.G. Novy Distinguished University Professor, Emeritus, Department of Microbiology and Immunology, University of Michigan Medical School at Ann Arbor, authors a post at the Small Things Considered blog on the dawn of proteomics, the large-scale study of proteins, with a f...

When the heads of the Centers for Disease Control and Prevention, the Food and Drug Administration, and the National Institute of Allergy and Infectious Diseases came to see us last week, they had some good news. The second wave of the H1N1 virus (known to the rest of us as swine flu) had reache... Read More
A common type of bacteria could help curtail the spread of mosquito-borne diseases by making the pests more resistant to infection, according to a study published Thursday in the US journal Cell.
The research built on an earlier study that found the lives of one type of disease-carrying mosqu... Read More
Scientists from Binghamton University and State University of New York have discovered key regulators required for the formation of biofilms - communities of bacteria in self-produced slime - which could lead to new ways for treating chronic infections.
These biofilms may be found almost anyw... Read More
In the antibiotic-resistance world, MRSA gets most of the press. Sometimes, C. difficile works its way into a headline or two. But here's a reminder that other bacteria are growing stronger as well.
A study published online Wednesday in the journal Infection Control and Hospital Epidemiology ... Read More
Everyone needs a little bit of "me time" now and again, but too much solitude can make us lonely and irritable and put us in a not-quite-right state of mind. According to recent medical research reported by Discovery News, similar stir-craziness has been observed in bacteria that are sequestered... Read More
Aker University Hospital is a dingy place to heal. The floors are streaked and scratched. A light layer of dust coats the blood pressure monitors. A faint stench of urine and bleach wafts from a pile of soiled bedsheets dropped in a corner.
Look closer, however, at a microscopic level, and th... Read More
An international group of researchers has sequenced and characterized the genome of a cavity-causing bacterial species called Bifidobacterium dentium, identifying key features that have helped the bug become a tooth decay specialist.
The team, which includes collaborators from Europe, the UK,... Read More
A new study reports a surge in drug-resistant strains of a dangerous type of bacteria in US hospitals: Acinetobacter strikes patients in Intensive Care Units (ICUs) and others and often causes severe pneumonias or bloodstream infection, some of which are now resistant to imipenem, an antibiotic ...

University of Delaware researchers have uncovered a novel means of conquest employed by the common reed, Phragmites australis, which ranks as one of the world's most invasive plants.
The invasive strain, which hails from Eurasia, overtakes its "native" cousin, which has lived in North America... Read More

My new paper in Nature (using a Creative Commons license so anyone has access to it) on a "Phylogeny Driven Genomic Encyclopedia of Bacteria and Archaea." In this paper we describe our project to fill in the gaps in the tree of life (of bacteria and archaea" with genome sequences and thus corre... Read More
At least 111 million doses of vaccine against pandemic H1N1 influenza are now available and least 60 million people have already been immunized, according to the Centers for Disease Control and Prevention. "The vaccine supply is getting better and better, and surveys are showing that the initial... Read More
Antibiotic resistance in the natural environment is rising despite tighter controls over our use of antibiotics in medicine and agriculture, Newcastle University scientists have found.
Bacterial DNA extracted from soil samples collected between 1940 and 2008 has revealed a rise in background ... Read More
Scientists have identified a strain of antibiotic-resistant tuberculosis that thrives in the presence of rifampin, a front-line drug in the treatment of tuberculosis. The bacterium was identified in a patient in China and is described in a study by researchers at the Johns Hopkins Bloomberg Scho... Read More
A report published in the new journal Science Translational Medicine has made an interesting discovery concerning the relationship between sugar intake and the balance of intestinal flora. Researchers have discovered that a diet high in sugar and fat substantially alters the bacterial compositio... Read More
In a novel study, researchers from University of Gothenburg, Sweden have found that the cellulose produced by bacteria could be used to develop artificial blood vessels in the future.
They say that bacterial cellulose carries a lower risk of blood clots than the synthetic materials currently ... Read More
