Helicobacter pylori, the bacterium largely associated with gastritis and peptic ulcers in humans, may invade and replicate in gastric epithelial cells say researchers from China. This discovery disputes prior views of H. pylori as a noninvasive pathogen and could offer significant insight into ... Read More
The need to re-formulate the influenza virus vaccine in response to viral antigenic drift and shift makes for complex logistics of vaccine production and administration. Surveillance programs must be conducted each year to identify strains that are likely to predominate and cause disease. Wouldn... Read More
Jeff Fox of Microbe magazine interviews Michael Brennan of Aeras Global TB Vaccine Foundation on efforts to develop a tuberculosis vaccine. Aeras is focusing a substantial portion of its vaccine development strategy and efforts on the venerable but flawed Bacille Calmette-Guerin (BCG) vaccine Read More
Xenotropic murine leukemia virus–related virus (XMRV) has been the subject of many studies since its discovery in 2006, but conflicting reports have created an unclear picture of XMRV's role in human disease. In three recent studies published in the November 15 issue of The Journal of Infectious... Read More
A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report.
The planarian flatworm, Schmidtea mediterranea, is perhaps best known for... Read More
Two studies appearing in the October 14, 2010 New England Journal of Medicine and funded by the National Institutes of Health helped influence the World Health Organization (WHO) to change its guidelines this year for the treatment of HIV infection in certain women and children. The recently up... Read More
A flu vaccine made through a speedier production method appears to be as safe and effective as one produced in the traditional way, a study suggests.
The conventional flu vaccine is produced using chicken eggs to grow the virus, a slow process that makes it hard to quickly boost production in... Read More
Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles.
Using a rela... Read More
Malaysia could be the first country in Asia to use genetically modified mosquitoes to battle a rise in dengue fever, government authorities said Monday. Read More
Bioluminescence is as widespread as it is wild and mysterious. Jack-o'-lantern mushrooms, flashlight fish and fireflies are among the multitude of organisms that bioluminesce. Scientists are still finding previously unknown examples of the phenomenon, especially at sea, where bioluminescent spec... Read More
Psi Wavefunction, an undergraduate in the Department of Botany, University of British Columbia, and the host of the blog Skeptic Wonder: Protists, Memes and Random Musings, has authored a guest post on Small Things Considered that looks at some confusing terminology associated with phylogenies:

Researchers have discovered the crystal structures of pumps that remove heavy metal toxins from bacteria, making them resistant to antibiotics.
The finding offers a better understanding of bacterial resistance to antibiotics that could ultimately help drug researchers develop treatments to co... Read More

Researchers from the University of Florida have discovered a chemical compound made from a type of bacteria found in the Florida Keys that appears to be effective in fighting colon cancer in preclinical experiments. Read More
It’s now much easier to pinpoint biological hot spots in the world’s oceans where some inhabitants are smaller than, well, a pinpoint.
Researchers have built a device that can count and classify microscopic algae called phytoplankton that range in size from one to hundreds of microns—the smal... Read More
Some bacteria grow electrical hairs, known as nanowires, that let them link up in big biological circuits.The discovery suggests that microbial colonies may survive, communicate, and share energy in part through electrically conducting hairs.
The finding is reported this week in Proceedings ... Read More
This episode: Using bacteria to recover precious metals like palladium!
The subject of this year’s top microscope photo in the 36th annual Nikon Small World competition looks more like neon suspension bridges or sailboats than what it really is: mosquito heart muscle magnified 100 times.
The image, which used flourescence technology to highlight different parts o... Read More
Just about a month ago, the disease-geek world was riveted by news of the “Indian superbug“: common bacteria carrying a newly recognized gene that confers profound multi-drug resistance, and that was linked to travel between Europe and South Asia, especially for medical tourism.
The gene, whi... Read More
The same types of bacteria found in arterial plaque, which causes atherosclerosis, are also found in the mouth and gut, according to the first general survey of all bacteria found in plaques from the mouth, gut and blood.
The study, conducted by researchers from Cornell and University of Goth... Read More
