A new study developed at the University of Colorado School of Medicine at the Anschutz Medical Campus links the virus that causes chicken pox and shingles to a condition that inflames blood vessels on the temples and scalp in the elderly, called giant cell arteritis.
Giant cell arteritis, whi... Read More
To determine how long Ebola virus could remain infectious in a body after death, National Institutes of Health (NIH) scientists sampled deceased Ebola-infected monkeys and discovered the virus remained viable for at least seven days. They also detected non-infectious viral RNA for up to 70 days ... Read More
Our bodies and homes are covered in microbes -- some good for us, some bad for us, and some just along for the ride. As we learn more about the germs and microbes who share our living spaces, TED Fellow Jessica Green asks: Can we design buildings that encourage happy, healthy microbial environme... Read More

In this short blog post, I "write" on Petri dishes with bioluminescent bacteria to create words and poems in "living light." I also write a haiku to quorum sensing in the same style! Read More
Malaria: shaking chills & fever (followed by sweats, not specifically mentioned in this case), is a characteristic of malaria that is unforgettable once one has had it (I had malaria four times).
Thick blood smears is de rigueur.
Four Web-based training modules developed by Johns Hopkins Medicine for emergency department personnel who treat patients with infectious diseases are now available on the Centers for Disease Control and Prevention (CDC) website.
Titled Ebola Preparedness: Emergency Department Guidelines, the... Read More
The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago. Now research from the University of Washington looking at some of the planet’s oldest rocks finds evidence that 3.2 billion years ago, life was already pulling nitrog... Read More
Infections lurking on the margins of civilization are becoming more likely to cause outbreaks as the climate changes, researchers say. Ravens, rodents and rattlesnakes are moving to new locales as rainfall and temperatures shift over time (ClimateWire, Dec. 14, 2011).

Cryptosporidium (Crypto) is a parasite that causes diarrheal disease. Crypto can live in the intestine of humans and animals and is passed in the stool of an infected person or animal. This parasite is very resistant to chlorine-based disinfectants and is protected by an outer shell that allows ... Read More
Combining experimental data from X-ray crystallography, NMR spectroscopy, cryoelectron microscopy and lipidomics, researchers have built a complete model of the outer envelope of an influenza A virion for the first time. The approach, known as a coarse-grained molecular dynamics simulation, has ... Read More
While it’s easy to think about mosquitoes as a mere portal for shuttling malaria and other diseases from one person to another, the insects have their own immune response to infection.
After sucking down a blood meal, mosquitoes ramp up production of immune system proteins to fight off potent... Read More
When exposed to nitrogen fertilizer over a period of years, nitrogen-fixing bacteria called rhizobia evolve to become less beneficial to legumes – the plants they normally serve, researchers report in a new study.
These findings, reported in the journal Evolution, may be of little interest to... Read More
Bacteria are everywhere on your skin, hair and eyelashes, to name a few of their homes. Bacteria are even in your soap, the very thing you thought washed all the bacteria away.
As long as the bacteria keep their numbers small, there's nothing wrong with them living in soap. But every once in ... Read More
I am Bibha Dahal, Graduate Teaching Assistant from South dakota State University, Brookings, SD. I have attached the image of nitrogen fixing bacteria, with water drop like appearance, grown on Nitrogen Free Medium, incubated at 28 degree Celsius for 4 days at microaerophilic condition.

Switchgrass successfully removed up to 40 percent of the PCBs from contaminated soils in lab experiments. When a PCB-oxidizing microorganism joined in, the removal rate reached 47 percent.
The researchers investigated how adding an aerobic PCB-oxidizing microorganism could enhance the oxidati... Read More
If ever there was proof of the power of small things, surely this is it. Last year, came the suggestion that sponges transformed Earth's deep oceans 750 million years ago, turning them into an oxygen-rich haven for life. Now it seems tiny bacteria living inside the sponges also played a part in ... Read More
Bacteria typically thrive in communities where colonies of many different species collaborate and support each other's growth and exchange nutrients.
However, it has not been clear whether they do this only by releasing the metabolites into the cell environment for their neighbors to pick up,... Read More
The typical Escherichia coli, the laboratory rat of microbiology, is a tiny 1-2 thousandths of a millimeter long. Now, by blocking cell division, two researchers at Concordia University in Montreal have grown E. coli that stretch three quarters of a millimeter. That's up to 750 times their norma... Read More
On May 30, 2012 Brianna Dannen, Public Health Nurse at the Clark County Health District (CCHD), received a call from Bob Williamson at Clark College. Mr. Williamson called to report that a child of a Clark College student enrolled in a microbiology class, BIOL&260, taught by Travis Kibota was i... Read More
