New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant.
The scientists followed the killer whales by boat, trying to catch the precise moment the a... Read More
Escherichia coli is no stranger to the human body. In around 20% of us, E. coli is the predominant species in our gastrointestinal tract, where it lives as a commensal. But when E. coli gets out of hand it can cause anything from gastroenteritis to sepsis to urinary tract infections. It's those ... Read More
In a new study, scientists have determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.
In their finding, a team of researchers, led by Dr. Steph... Read More

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Scientists may have pinpointed a potential way to prevent the flu by identifying a protein that amps up the immune system, according to a new animal study.
The synthetic protein, called EP67, is able to trigger an immune response to the "threat" of the flu virus within a couple of hours in mi... Read More
People who harbor ulcer-causing bacteria in their stomachs may be protected against some diarrheal diseases, suggests a new study.
The bacterium, called Helicobacter pylori, is especially common throughout the developing world, but only causes symptoms in a minority of those it infects.

Beer discovered two years ago onboard a shipwreck from the mid-1800s could possibly be recreated using living bacteria discovered in the brew, Finnish researchers announced last Thursday.
According to Terhi Kinnunen of Reuters, Annika Wilhelmson from VTT Technical Research Centre of Finland s... Read More
Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
The scientists and other experts said the work was a giant step towar... Read More
Some bacteria fight off antibiotics even as they starve.
For years, scientists believed antibiotics failed to work against starving bacteria because the medicines' target spot within the bacteria had slowed or gone dormant.
As it turns out, the bacteria's starvation triggers a reaction tha... Read More
Across the horizon and miles out to sea toward the north, the Atlantic Ocean's own spring and summer ritual is unfolding: the blooming of countless microscopic plant plankton, or phytoplankton.
In what's known as the North Atlantic Bloom, an immense number of phytoplankton burst into color, f... Read More
It was recently reported - at the National Foundation for Infectious Diseases 15th Annual Conference on Vaccine Research - that the rate of adverse effects from a third dose of the measles, mumps and rubella (MMR) vaccine is the same as those of the second dose. This was conducted as part of a C... Read More
Mothers with IgG antibodies to Toxoplasma gondii at delivery are at risk for later self-harm or suicide, particularly if they have higher titers against the parasite, a Danish study found.
The risk of self-directed violent behavior was increased 1.53-fold (95% CI 1.27 to 1.85, Psk rose to 1.9... Read More
Due to low uptake of the MMR vaccine across the world, we have seen a dramatic rise in the number of cases of measles and mumps. These have gone against efforts to eradicate these diseases. Perceived safety concerns have led to the rise in uptake of single vaccines and thus for a number of years... Read More
Invasive species aren't just exotic animals, scary snakes or annoying insects. They can also be bacteria and viruses that kill people. Although it's difficult to say what the most harmful invasive species is, "I'd probably point to West Nile virus," says Christopher Dionigi of the federal Nation... Read More
It’s true! Each year it rains viruses, more than a trillion of them per acre over thousands of forested acres in the USA. This is the work of the airborne arm of the USDA Forest Service, part of their efforts to reduce the devastation to hardwood forests caused by the imported gypsy moth, Lymant... Read More
Community in the deep seabed uses so little oxygen that it is no longer clear where the lower bound for life lies.
Most humans would struggle to last for much more than a minute under water without coming up for air, whereas some seals can manage more than an hour — but a microbial community ... Read More
