Global Warming May Spawn New Disease Outbreaks

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).

Drug Combinations a Good Approach for Infectious Fungus

Researchers at the University of Toronto have discovered that Candida albicans — a leading cause of potentially fatal hospital-acquired infections — rarely develops resistance to combination drug therapy and, when it becomes resistant, it also becomes less dangerous.

The team may also have fo... Read More

Research Shows Asian Herb Holds Promise as Treatment for Ebola Virus Disease

New research that focuses on the mechanism by which Ebola virus infects a cell and the discovery of a promising drug therapy candidate is being published February 27, 2015, in the journal Science. Dr. Robert Davey, scientist and Ewing Halsell Scholar in the Department of Immunology and Virology ... Read More

Ancient rocks show life could have flourished on Earth 3.2 billion years ago

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

Johns Hopkins and CDC prepare emergency department staff to care for patients with infectious disease

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

Unlocking the Key to Immunological Memory in Bacteria

A powerful genome editing tool may soon become even more powerful. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have unlocked the key to how bacteria are able to “steal” genetic information from viruses and other foreign invaders for use in their own immunological me...

Long-term nitrogen fertilizer use disrupts plant-microbe mutualisms

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

Were early seas transformed by sponge microbiome?

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

TWiP 84: Bigfoot

Vincent, Dickson, and Daniel consider the delivery of anti-trypanosome nanobodies to the tsetse fly via a bacterial symbiont, and present a new case study.

Unusual Bacteria Discovered in Deepest Ocean Trench

Researchers from Japan discovered microscopic bacteria thrive in the canyon called Challenger Deep, which is the lowest point on Earth's surface and the deepest part of the Mariana Trench, the team reports Feb. 23 in the journal Proceedings of the National Academy of Sciences. In particular, the... Read More

Study: Reusable Plastic Produce Containers Harbor Bacteria Even After Being Cleaned, Sanitized

Reusable plastic containers used to transport large amounts of fruits and vegetables to grocery stores can continue to harbor potentially harmful bacteria directly on their surfaces, even after undergoing industry-standard cleaning and sanitizing, according to a new study conducted by researcher...

'Virtual virus' unfolds the flu on a CPU

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

Small Loop in Human Prion Protein Prevents Chronic Wasting Disease

Chronic wasting disease (CWD) — an infectious disease caused by prions — affects North American elk and deer, but has not been observed in humans. Using a mouse model that expresses an altered form of the normal human prion protein, researchers at University of California, San Diego School of Me... Read More

Burden of Clostridium difficile Infection in the United States

The deadly bacterial infection Clostridium difficile is estimated to have afflicted almost half a million Americans and caused 29,000 deaths in 2011, according to a study by the Centers for Disease Control and Prevention published Wednesday in The New England Journal of Medicine. The estimate is... Read More

Swine flu claims 800 lives across India, Ahmedabad prohibits mass gatherings

Killer swine flu attacks India. It’s H1N1, the same strain which was responsible for 1918 Spanish and 2009 flu pandemic that was the deadliest natural disasters in human history. More than 11,000 cases have been reported in India. The death toll has risen to more than 700. Number of death and in... Read More

Mutant bacteria that keep on growing

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

Microbe helps switchgrass 'detox' polluted soil.

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

WHO calls for action over Mers virus

Too little is being done to control the spread of Middle East Respiratory Syndrome, which has infected 50 people in Saudi Arabia so far this month, the World Health Organization has warned.

The rising number of cases in health-care facilities indicates current infection-control measures are n... Read More

Gerbils and Silk Road to blame for plague

Most would choose the cuddly gerbil over the much-maligned rat. But the latter's bad reputation may not be fully deserved. Central Asian rodents, not rats, prospering under warm variations in climate, could have been to blame for the arrival of the Black Death in Europe in 1347 and for repeated ... Read More
