Could the bacterial populations in your intestines predict the onset of colon cancer? Participants will discuss new research in mouse models that suggests a major shift in microbial population dynamic prior to the onset of tumors as well as the general promise microbiome research holds for the ...

Trypanosome Lytic Factor (TLF) has emerged as a novel arm of innate immunity that is only present in humans and select non-human primates. TLF was originally discovered in human blood as a minor form of High-density lipoprotein (HDL), also known as a good cholesterol, that rapidly kills the Afri... Read More

Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. What effect does this process have on the microorganisms that naturally exist in the water in this process?

Antimicrobial peptides (AMPs) are part of the innate immune system that is widely distributed in nature, acting as a defense mechanism against invading microorganisms. AMPs have potent antimicrobial activity against a range of microorganisms including fungi, bacteria and viruses. In view of grow... Read More

The emergence of human infections with avian influenza viruses (H7N9 and H5N1) have raised concerns about the virus gaining the ability to spread person-to-person, potentially causing a deadly pandemic. So far the number of human cases has been limited but the mortality rates have been high. In ... Read More

There was much written concerning the research published earlier this month in Science, where researchers from China’s Harbin Veterinary Research Institute reported creating an avian H5N1 (highly pathogenic) and pandemic 2009 H1N1 (easily transmissible) hybrid, that according to them, achieved ...

Plants associated bacteria play a key role in host productivity and health. These bacteria are phylogenetically diverse and form interactions considered neutral, beneficial or detrimental. A better understanding of these interactions will have a direct impact in agriculture by promoting sustaina... Read More

A cocktail of non-pathogenic bacteria naturally occurring in the digestive tract of healthy humans can protect against a potentially lethal E. coli infection in animal models according to research presented today at the 113th General Meeting of the American Society for Microbiology. The researc... Read More

Scientists at the University of California, Davis have engineered a strain of photosynthetic cyanobacteria to grow without the need for light. They report their findings today at the 113th General Meeting of the American Society for Microbiology.

“In this work, we used synthetic biology appr... Read More

Bacteria that glide together… make art together? This contender in the Art of Science competition run by Princeton University in New Jersey, entitled The history of gliding, depicts the squiggly gliding paths of the bacteria Myxococcus xanthus.

M. xanthus are social bacteria that move in coor... Read More

I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a labo... Read More

Bacterial resistance to antibiotics is bad enough, but what if drug resistance also gives bacteria the ability to fend off attacks by the immune system? In a study in mBio this week scientists identify a lose-lose situation with colistin and Acinetobacter baumannii: bacteria resistant to colisti... Read More

Norovirus is the most common cause of acute gastroenteritis in the United States. Each year, it causes about 21 million illnesses and contributes to about 70,000 hospitalizations and 800 deaths. Norovirus is also the most common cause of foodborne-disease outbreaks in the United States. Research... Read More

Food microbiology laboratories continue to submit false negative results and false positive results on a routine basis. A retrospective study of nearly 40,000 proficiency test results over the past 14 years, presented today at the 113th General Meeting of the American Society for Microbiology, ... Read More

Michael Pollan, food author, activist and journalism professor, wrote this week’s cover story about the organisms with which we share our bodies — and how we’re dependent on them. His book “Cooked: A Natural History of Transformation” came out last month. His last article for the magazine was ab... Read More

In 2008 researchers from the University of Southern Denmark showed that the drug thioridazine, which has previously been used to treat schizophrenia, is also a powerful weapon against antibiotic-resistant bacteria such as staphylococci (Staphylococcus aureus).

Antibiotic-resistant bacteria is... Read More

Whether the microorganisms routinely inhabit the upper troposphere -- perhaps living on carbon compounds also found there -- or whether they were simply lofted there from the Earth's surface isn't yet known. Airborne microbes are of interest to atmospheric scientists, because they could play a r... Read More
