Bat SARS-like coronavirus that infects human cells

The SARS pandemic of 2002-2003 is believed to have been caused by a bat coronavirus (CoV) that first infected a civet and then was passed on to humans. The isolation of a new SARS-like coronavirus from bats suggests that the virus could have directly infected humans. Read More

Increasing toxicity of algal blooms tied to nutrient enrichment and climate change

Nutrient enrichment and climate change are posing yet another concern of growing importance – an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, which threatens aquatic organisms, ecosystem health and human drinking water safety.

First fungal farmers found harvesting bacteria

It's a mould breaker. Researchers have discovered the first fungus that behaves like a farmer.

We already know that soil fungi can help bacteria travel quickly from A to B. The fungal filaments provide favourable conditions for the bacteria, and so act as "highways" through the soil. But thes... Read More

New substance effectively combats multi-resistant bacteria

In Europe alone, more than 25,000 people die each year from infections caused by multi-resistant bacteria. Researchers from University of Copenhagen have now developed and characterized a substance that quickly and effectively kills the virulent bacteria. The substance employs a multifunctional ...

How a Young Boy, a Cow and a Milkmaid Helped to Conquer Smallpox [Video]

If you aren’t familiar with the TEDEd series of animated videos, you should be. The series pairs professional educators with top-notch animators to create short video “lessons” on a huge variety of topics in science, medicine and history.
 The latest episode features several of the early attempt... Read More

Virus-induced fever might change bacteria from commensal to pathogen

Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More

RI Hospital study measures impact of education, information on hand hygiene compliance

How often do you clean your hands? A study at Rhode Island Hospital observed staff on 161,526 occasions to monitor how often they cleaned their hands (ie, hand hygiene) between July 2008 to December 2012 and found that hand hygiene compliance improved from 60 percent to 89 percent. The study is ... Read More

Listeria’s resistance to disinfectants

Prevention of listeriosis relies on killing the causative agent, normally the bacterium Listeria monocytogenes, in dairies and other food-processing facilities. A number of disinfectants are used for this purpose, most often quaternary ammonium compounds such as benzalkonium chloride (BC). Unfor... Read More

HIV -- Geneticists map human resistance to AIDS

The key to future HIV treatment could be hidden right in our own genes. Everyone who becomes infected deploys defense strategies, and some even manage to hold the virus at bay without any therapy at all. This immune system struggle leaves its mark within the pathogen itself – genetic mutations t... Read More

U.N. Confirms Polio Outbreak in Syria

Microbiome in gut, mouth, and skin of low birth weight infants differentiate over first weeks after birth

Low birth weight infants are host to numerous microorganisms immediately after birth, and the microbiomes of their mouths and gut start out very similar but differentiate significantly by day 15 according to a study in mBio this week. Researchers from Stanford University and the University of Pi... Read More

Researchers discover a new protein fold with a transport tunnel

The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... Read More

Changes in the Field Can Cut Food Contamination

Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.

For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More

HPV Strains Affecting African-American Women Differ from Vaccines

Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers at Duke Medicine.

The findings, presented on Oct. 28, 2013, at the 12th annual International... Read More
