Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a s... Read More
After studying unusual skin lesions seen in two orphaned sea otter pups, University of Florida scientists and their collaborators have identified a previously unknown poxvirus in the infected animals.
“To our knowledge, this is the first report of a poxvirus in a mustelid, the group of mammal... Read More
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More
Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.
Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More
Imagine a pill that helps people control diabetes with the body’s own insulin.
Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein called Glucagen-like peptide 1 (GLP-1).
A 2003 study led by Atsushi Suzuki of th... Read More
The use of viruses that kill bacteria as a tool for treating infections are under study again by Western researchers and governments.
For decades, patients behind the Iron Curtain were denied access to some of the best antibiotics developed in the West. To make do, the Soviet Union invested h... Read More
New research shows that the whip-like appendages on many types of cells are able to synchronise their movements solely through interactions with the fluid that surrounds them.
Many different types of cell, including sperm, bacteria and algae, propel themselves using whip-like appendages know... Read More

Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.

The Ebola virus has proven deadly to both people and animals.
The epidemic that started in 2014 has so far taken the lives of over eight thousand people in West Africa. The virus also killed an estimated 5,500 gorillas in the Lossi Sanctuary of the Republic of Congo in 2003. But scientists sa... Read More
Two of the four known groups of human AIDS viruses (HIV-1 groups O and P) have originated in western lowland gorillas, according to an international team of scientists from the Perelman School of Medicine at the University of Pennsylvania, the University of Montpellier, the University of Edinbur...

Two miles below the surface of the ocean, researchers have discovered new microbes that “breathe” sulfate.
The microbes, which have yet to be classified and named, exist in massive undersea aquifers — networks of channels in porous rock beneath the ocean where water continually churns. About ... Read More
An antibiotic with the ability to vanquish drug-resistant pathogens has been discovered — through a soil bacterium found just beneath the surface of a grassy field in Maine. Although the new antibiotic has yet to be tested in people, there are signs that pathogens will be slow to evolve resistan... Read More
Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More
The World Health Organization expressed worry on Wednesday about a second cluster of Ebola virus patients in Nigeria — in the center of its oil industry — because one of the three confirmed victims was a doctor who had treated patients and socialized after he became contagious.
The doctor, in... Read More
Exposed for 3 minutes outdoors in the gymnasium of the Inter American University of Puerto Rico. Medium used for fungi PDA. Culture medium used for bacteria TSA. Incubated at 37 degrees for 48 hours. Read More
Why a field researcher from America has exposed his colon to the gut microbiome of a tribesman from Tanzania.
It's not often we encounter a story that begins with a line like this:
“AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey b... Read More
Scientists say they have discovered a natural compound from bacteria that may prove to be a potent new antibiotic. This news comes at a time when many current antibiotics are losing their oomph — germs become resistant to them.
The new compound is especially intriguing because it appears that... Read More
Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

A nasal vaccine in development by researchers at The University of Texas at Austin has been shown to provide long-term protection for non-human primates against the deadly Ebola virus. Results from a small pre-clinical study represent the only proof to date that a single dose of a non-injectable... Read More
