A global fund should be created to speed development of much-needed new antibiotics to counter the growing threat of drug-resistant superbugs, a British-government backed review said on Thursday.
The review, headed by the leading economist and former Goldman Sachs chief Jim O'Neill, said far ... Read More
If the reader does not believe that viroids and satellites are distinctive, then surely prions, infectious agents composed only of protein, must impress.
The question of whether infectious agents exist without genomes arose with the discovery and characterization of infectious agents associat... Read More
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
If you were about to enter a crowded subway during flu season, packed with people sneezing and coughing, wouldn't it be helpful if your immune system recognized the potentially risky situation and bolstered its defenses upon stepping into the train?
After ingesting a meal of blood, mosquitoes... Read More
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
A clinical trial in Liberia of a drug to treat Ebola has been halted because of a sharp decline in the number of people infected with the virus, and studies in West Africa of other potential treatments are also facing problems finding patients.
The halted trial was testing the antiviral drug ... Read More
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
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
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
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?
Click "sour... Read More
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
A closer look at gut bacteria suggests exclusively breastfed babies have an easier time transitioning to solid food—potentially with fewer stomach aches.
Researchers found differing amounts of about 20 bacterial enzymes in exclusively breastfed babies when compared to exclusively breastfed ba... Read More
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
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...

Pure culture of Pseudomonas sp. isolated from rain collected at Virginia Tech, USA.
Incubation Conditions: 48 hours at 28°C + 24h at 20°C on EMB Agar
It can be distinguished two types of colonies following a gradient of culture density.
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.
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...

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
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
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
