Hi Vincent,


I thought you and the rest of the TWiM/TWiP folks would be interested in the following paper: Transferred interbacterial antagonism genes augment eukaryotic innate immune function, published online in Nature this week... Read More

More infectious diseases emerging because of climate change

The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.

In an article publishe... Read More

Canned fruit safer than the frozen variety

Canned fruit is often safer than the frozen variety according to University of NSW Associate Professor Julian Cox, an expert in food microbiology.

"The heat treatment used to make canned products shelf stable in ambient temperatures is much more than sufficient to kill micro-organisms includi... Read More

Recent Paper Shed’s Light on Effect of Using Antibiotics While Traveling

When I jetted off to South America a year and a half ago, my doctor sent me with a bottle of Ciprofloxacin in case of an unfortunate bout of food poisoning. I thought little of it then, but what does it mean when millions of travelers head to developing countries with antibiotics?

Big Data and Bacteria: Mapping the New York Subway’s DNA

Aboard a No. 6 local train in Manhattan, Weill Cornell researcher Christopher Mason patiently rubbed a nylon swab back and forth along a metal handrail, collecting DNA in an effort to identify the bacteria in the New York City subway.

In 18 months of scouring the entire system, he has found g... Read More

In Treating Ebola, Even Using a Stethoscope Becomes a Challenge

Doctors treating Ebola patients while wearing “the full spacesuit” — protective gear, including waterproof hoods — are struggling with a clinician’s dilemma: what to do if they can’t use one of the oldest, most basic tools in medicine — a stethoscope.

It’s not safe to cut holes in the hood, a... Read More

Research finds that malaria parasites are unlikely to jump to humans

In recent years, public health experts have increasingly explored the idea of eliminating the most dangerous malaria-causing parasite. But they have questioned whether getting rid of this species, called Plasmodium falciparum, would allow other species of the parasite to simply jump into the gap... Read More

Bacteria jump between species more easily than previously thought

A new study suggests that bacteria may be able to jump between host species far easier than was previously thought. Researchers discovered that a single genetic mutation in a strain of bacteria infectious to humans enables it jump species to also become infectious to rabbits. The discovery has m... Read More

Measles in the brain: Fusion gone awry

The entry of enveloped viruses into cells begins when the membrane that surrounds these virus particles fuse with a cell membrane. The process of virus-cell fusion must be tightly regulated, to make sure it happens in the right cells. The fusion activity of measles viruses isolated from the brai... Read More

Breastfeeding, Other Factors Help Shape Immune System Early in Life

Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby’s immune system development and susceptibility to allergies and asthma by what’s in their gut.

The striking findings from a series of studies further advance the so-called hygiene hypothesis theory that ... Read More

Record Keeping Helps Bacteria’s Immune System Fight Invaders

Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity.

Two experiments undertaken at the Department of Energy's SLAC National Accelerator Laboratory provide new insight at the heart of bacterial adaptive de... Read More

Study shows oysters, mussels have low levels of disease, parasites

NOAA's first-ever long-term report of the national distribution of parasites and disease in mussels and oysters, using data gathered between 1995 and 2009, provides a new data set for coastal resource management and shows the occurrence and severity of disease and parasite infections to be gener...

In a warmer world, ticks that spread disease are arriving earlier, expanding their ranges

In the northeastern United States, warmer spring temperatures are leading to shifts in the emergence of the blacklegged ticks that carry Lyme disease and other tick-borne pathogens. At the same time, milder weather is allowing ticks to spread into new geographic regions. Findings were published ... Read More

Friendly fungi: How they could help barley growers feed the world without chemicals

Botanists from Trinity College Dublin have made a breakthrough discovery that could save barley farmers sleepless nights and millions of Euro each year: naturally occurring plant-friendly fungi prevent crop-ravishing diseases from spreading, and also aid plant survival in testing environmental c...

TLR9: Two rings to bind them?

University of Tokyo researchers have elucidated how Toll-like receptor 9 (TLR9) binds to pathogen DNA, activating the innate immune system. This discovery is vital for the design of new antiviral, antibacterial, allergy and other drugs targeting TLR9.

Invading pathogens such as bacteria or vi... Read More

Darwin's Finches Get Their Genomes Sequenced

Researchers have sequenced the genomes of all 15 species of Darwin’s finches, revealing a key gene responsible for the diversity in the birds’ beaks. The study, published online in Nature this week, also redraws the family tree of these iconic birds, whose facial variations helped Charles Darwin... Read More

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

CU neurologist finds link between virus causing chicken pox and giant cell arteritis
