New research shows that nearly 1 in 5 cases of infection with the potentially deadly fungus Cryptococcus neoformans are caused by not one but multiple strains of the pathogen. Researchers from the Institut Pasteur and the University of Minnesota Medical School reported their findings May 19 in the inaugural issue of mBioâ“ž¢, the first online, open-access journal published by the American Society for Microbiology. "Koch's postulates are criteria establishing a...

Army scientists have discovered a way to "trick" the bacterium that causes anthrax into shedding its protective covering, making it easier for the body's immune system to mount a defense. The study, which appears in this month's issue of the journal MICROBIOLOGY, could lead to new approaches for treating anthrax infection. Bacillus anthracis, the causative agent of anthrax, is particularly lethal because of its protective coating, or capsule, which enables the pathogen to escape destruction...

SARASOTA, Fla., May 12 /PRNewswire-USNewswire/ -- Trillions of bacteria might help clean up the Gulf oil spill, a specialized company reports. Osprey Biotechnics, Inc., a pioneer in breeding beneficial bacteria, says it estimates that 55 gallons of the product it calls Munox would treat 36.5 square miles of Gulf waters. Slightly more than 100 55-gallon drums would cover 4000 square miles. "Mother Nature will take 100 years or more to clean up this mess," comments Executive Vice President...

The US Department of Agriculture released new standards on Monday with the aim of reducing the levels of salmonella and campylobacter in poultry, which if successful, the government said could prevent as many as 65,000 foodborne illnesses every year. The USDA said that stricter standards would make slaughterhouses more accountable by reducing the frequency of foodborne illnesses in juvenile chickens and turkeys. The standards would set an acceptable percentage of sampled...

We are not alone"”even in our own bodies. The human gut is home to 100 trillion bacteria, which, for millions of years, have co-evolved along with our digestive and immune systems. Most people view bacteria as harmful pathogens that cause infections and disease. Other, more agreeable, microbes (known as symbionts) have taken a different evolutionary path, and have established beneficial relationships with their hosts. Still other microbes may be perched somewhere in between, according...

In a first-of-its-kind experiment, the unique conditions of spaceflight will be used to examine how cells remain healthy or succumb to disease, particularly in the face of stress or damage. At 3:21 a.m. PDT on April 5, ASU Biodesign Institute researchers Cheryl Nickerson and her team, including Jennifer Barrila and Shameema Sarker, will see their latest experiment launched into low earth orbit aboard the space shuttle Discovery on mission STS-131.The goals of the team's research are to...

Mycobacterium tuberculosis (Mtb) possesses extraordinary survival ability by masking itself from the host immune system and persisting for decades inside the host. Speaking at the Society for General Microbiology's spring meeting in Edinburgh on March 31, Dr Kristine Arnvig provided further insight into how the bacterium causes tuberculosis (TB) by fine-tuning its behavior in response to its surroundings to escape detection. Understanding the genetic tools and tricks used by Mtb to control...

Pathogenic bacteria in the gut recognize their surroundings by detecting hormone signals from the host, which can prompt them to express lethal toxins. Intercepting these hormonal messages could be a better way to treat serious food-borne infections where antibiotics do more harm than good, explains Vanessa Sperandio speaking at the Society for General Microbiology's spring meeting in Edinburgh on Sunday. Gut bacteria, including harmful strains of Escherichia coli and Salmonella that cause...

The factors instrumental in triggering latent tuberculosis (TB) infection to progress into active disease have long remained elusive to researchers. New insight into the mystery is provided by Professor David Russell, speaking at the Society for General Microbiology's spring meeting in Edinburgh on Sunday. His work could help develop innovative strategies for treating the disease. Professor Russell and his group at Cornell University in New York, USA, have demonstrated that TB-causing...

CORVALLIS, Ore. "“ Fungi have significant potential for "horizontal" gene transfer, a new study has shown, similar to the mechanisms that allow bacteria to evolve so quickly, become resistant to antibiotics and cause other serious problems. This discovery, to be published Thursday in the journal Nature, suggests that fungi have the capacity to rapidly change the make-up of their genomes and become infectious to plants and possibly animals, including humans. They are not nearly as...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
