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
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
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, Amherst report their findings at the 113th General Meeting of the A... Read More
Microbial ecology may be a young field but it is well understood already that there is a broad spectrum of interactions between bacterial species, ranging from cooperative to competitive. In a recent paper researchers from John Mekalanos’ lab further characterized a recently discovered mechanism... Read More
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
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
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
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
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 ...

Gram stained slide from oil enrichment culture, samples enriched from soil. I would love to know what the HUGE bacilli are - can anyone help? Read More
Be part of the studio audience for the American Society for Microbiology 2013 General Meeting's live internet talk show, ASM Live. Host Stanley Maloy, Ph.D., Professor of Microbiology and Dean of th... Read More
Robert Koch is one of the key figures in early bacteriology, helping develop culture techniques (e.g. solid media), critical reasoning (e.g. Koch’s postulates), and disease etiology (e.g. cholera and tuberculosis). He also published the first photomicrographs of bacteria (Figure 1A) in his 1877 ... Read More
Another major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology. For instance, Joanna Aizenberg and her laboratory have pioneered using self-assembling synthetic nanofibers to generate capture-and-release devices t... Read More
The swine flu virus that caused a 2009 pandemic has been found in elephant seals off the central California coast, according to new research. The study, published in the journal PLoS ONE, is the first report of the virus H1N1 in any marine mammal. Researchers are now being advised to wear protec... Read More
Researchers from CNRS, Université Toulouse III -- Paul Sabatier and IRD have elucidated new molecular mechanisms involved in resistance to visceral leishmaniasis, a serious parasitic infection. They have shown that dectin-1 and mannose receptors participate in the protection against the parasite... Read More
The phrase "gut bacteria" might sound icky and repulsive, but modern science may have you soon thinking differently about the bugs that live in your intestinal system. Top researchers around the globe are exploring the bacteria that naturally reside in the bowels of both people and animals, and ... Read More
