New mechanisms of 'social networking' in bacteria

AMHERST, Mass. - Bacteria have traditionally been viewed as solitary organisms that "hang out on their own," says molecular biologist Kevin Griffith of the University of Massachusetts Amherst. However, scientists now realize that in fact, bacteria exhibit social behavior within groups. Read More

Three Roads to Cellular Compartments

In a recent post to ASM's blog Small Things Considered, Merry Youle writes a wonderful, sometimes thrilling description of the different forms of cellular compartments that have evolved over the last 4 billion years or so. From compartmentalized, lipid-bound membranes in eukaryotes to microcomp... Read More

The 'intraterrestrials': New viruses discovered in ocean depths

Deep sea microbiology is a rapidly-growing field that we know (not surprisingly) very little about. New research investigates the ecology of methane seep ecosystems and the interaction between archaea and viruses beneath the ocean floor. A newly-discovered virus seems to self-select for mutati...

Cattle-killer: Two parasites are better than one

When calves are infected by two parasite species at the same time, one parasite renders the other far less deadly, according to a new study published in the current journal of Science Advances Read More

These 6 Symptoms predict Ebola risk

When deciding whether a sick patient belongs in an Ebola treatment unit (ETU), doctors want to be right because any misdiagnosis is terribly dangerous.

Returning an Ebola case to the community leaves a patient untreated and prolongs the epidemic, but admitting someone with a different illness... Read More

Yes, We Were Warned About Ebola

"The conventional wisdom among public health authorities is that the Ebola virus, which killed at least 10,000 people in Liberia, Sierra Leone and Guinea, was a new phenomenon, not seen in West Africa before 2013. (The one exception was an anomalous case in Ivory Coast in 1994, when a Swiss prim... Read More

Dartmouth Investigators Develop Antibacterial Enzymes to Combat Drug-Resistant Bacterial Pathogens

By engineering antibacterial enzymes, Dartmouth investigators led by Karl Griswold, PhD are using novel strategies to target the prevalent drug-resistant bacterium Staphylococcus aureus. Recent papers in FEMS Microbiology Letters and Applied Microbiology and Biotechnology describe their findings... Read More

HeLa RNA is everywhere

The first immortal human cell line ever produced, HeLa, originated from a cervical adenocarcinoma taken from Henrietta Lacks. The cell line grew so well that it was used in many laboratories and soon was found to contaminate other cell lines. Now HeLa RNA has made its way into human sequence dat... Read More

Skin microbiome may hold answers to protect threatened gold frogs from lethal fungus

A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog's skin affects its likelihood of contracting disease. Read More

MALDI-TOF and the Clinical Microbiology Laboratory

In this interview, Dr. Robert Jerris, Director of Clinical Microbiology at the Children’s Healthcare of Atlanta Pediatric Hospital, discusses his experiences in implementing and using the MALDI Biotyper for clinical diagnostics use. In part one of our interview, Dr Jerris explains how this techn... Read More

NIH funds 9 antimicrobial resistance diagnostics projects

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has awarded more than $11 million in first-year funding for nine research projects supporting enhanced diagnostics to rapidly detect antimicrobial-resistant bacteria. The awardee institu... Read More

To fight nasty digestive bugs, scientists set out to build a better gut -- using stem cells

Researchers at the University of Michigan are studying the ecology of microbes in the GI tract in hopes of developing novel diagnostic tests and effective treatments for intestinal disease. How are they studying this? By creating tiny gut ecosystems! Using undifferentiated stem cells, the inv... Read More

Out of a pickle

For centuries - millenia even - people have learned to harness the power of microbes such as bacteria, yeasts, and other fungi for the purpose of improving the quality of foods. Some have been employed (accidentally or intentionally) to enhance flavor (i.e. cheeses, breads) while others have be... Read More

How a bacterial cell recognizes its own DNA

It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More

HIV can spread early, evolve in patients' brains

The AIDS virus can genetically evolve and independently replicate in patients' brains early in the illness process, researchers funded by the National Institutes of Health have discovered. An analysis of cerebral spinal fluid (CSF), a window into brain chemical activity, revealed that for a subs... Read More

Cytomegalovirus hijacks human enzyme for replication

Researchers at Princeton have discovered that cytomegalovirus manipulates a process called fatty acid elongation, which makes the very-long-chain fatty acids necessary for virus replication. Published in the journal Cell Reports on March 3, the research team identified a specific human enzyme--e... Read More
