The alarm system the helps immune system cells destroy invading bacteria points to a potentially new way to protect people from biological weapons, researchers report.
Cells in the immune system called macrophages normally engulf and kill intruding bacteria, holding them inside a membrane-bou... Read More
The highest rates of infection were in children, with 47 per cent of those aged five to 19 showing signs of having caught the virus. Older people were affected less, with only 11 per cent of people aged 65 or older becoming infected.
The findings come from an international collaboration led b... Read More
The polio virus has been found in the sewers of Cairo, and it appears to have come from Pakistan, the World Health Organization said Wednesday. Egypt has not had a case of polio since 2004. A vaccination drive is being planned for Feb. 25, and health workers are canvassing the neighborhoods wher... Read More
What cancerous conditions lead to what kinds of bacterial infections? If doctors knew, they could predict which patients would likely benefit from pre-treatment with certain kinds of antibiotics. A University of Colorado Cancer Center study published in this month's issue of the International Jo... Read More
A common type of bacteria may help pigs stay healthy during weaning. In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.

Virology was born in 1898, and has suffered from sampling bias ever since. For decades, viruses were defined by what they were not: not as big as a bacterium, not visible with a microscope, not culturable in the absence of a host. At the dawn of the 20th century, undiscovered viruses and aspirin... Read More
The storm clouds in Earth's atmosphere are filled with microbial life, according to a new study.
The research, published today (Jan. 23) in the journal PLoS One, revealed that hailstones drawn from storm clouds harbor several species of bacteria that tend to reside on plants, as well as thous... Read More
In early 2012 influenza virus researchers around the world decided to stop working on highly pathogenic avian influenza H5N1 virus. This decision came after work from the Fouchier and Kawaoka laboratories revealed the isolation of influenza H5N1 strains that can be passed among ferrets by aeroso... Read More
A toxin-antitoxin system is a set of two or more closely linked genes that together encode both a protein 'poison' and a corresponding 'antidote'. There are 3 types of these systems: Type I toxin-antitoxin systems rely on the base-pairing of complementary antitoxin RNA with the toxin's mRNA, Ty... Read More

Euplotes belongs to the class Nassophorea in the phylum Ciliophora; the ciliates, of which there are approximately 8,000 species, are generally considered to be the most evolved and complex of the p... Read More
Children with eczema have a more diverse set of bacteria in their guts than non affected children, finds a new study in BioMed Central's open access journal BMC Microbiology. The types of bacteria present were also more typical of adult gut microbes than for toddlers without eczema.
Eczema is... Read More
Troublesome strains of Staphylococcus aureus are often troublesome because they carry genes for superantigens and multiple antibiotic resistance. But don’t blame the bacteria. These genes are hitchhikers that arrived by horizontal gene transfer, embedded within mobile pathogenicity islands known... Read More
A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, whe... Read More
Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins th...

SketchyMicro is a unique and effective way to learn high-yield medical microbiology for the USMLE Step 1.
Dissatisfied with the current medical microbiology board review resources, SketchyMicro decided to take things into their own hands. Their review course takes the plethora of microorganis... Read More
While working out the structure of a cell-killing protein produced by some strains of the bacterium Enterococcus faecalis, researchers stumbled on a bit of unusual biochemistry. They found that a single enzyme helps form distinctly different, three-dimensional ring structures in the protein, one... Read More
Early life exposure to normal bacteria of the GI tract (gut microbes) protects against autoimmune disease in mice, according to research published on-line in the journal Science. The study may also have uncovered reasons why females are at greater risk of autoimmune diseases such as multiple scl... Read More

It’s not hard to see that men are more likely to engage in risky behaviors than women, or that crime rates are many times higher among men, but this tendency to break the rules also extends to male scientists, according to a study to be published on January 22 in mBio®, the online open-access jo...
