Almost everyone knows about Escherichia coli O157:H7, the culprit behind many headline-making outbreaks of foodborne illness in the United States. But the lesser-known relatives of this pathogenic microbe are increasingly of concern to food safety scientists. Read More
This digitally-colorized scanning electron micrograph (SEM) depicted large numbers of Gram-positive Enterococcus sp. bacteria.
“Enterococci, leading causes of nosocomial bacteremia, surgical wound infection, and urinary tract infection, are becoming resistant to many and sometimes all standard ... Read More
Altering microbial enzymes can lead to more powerful drugs that are effective against bacteria resistant to traditional antibiotics.
The evolution of antibiotic-resistant bacteria has left researchers scrambling to develop new, stronger antibiotics. Now researchers have successfully used a met... Read More
Glenn Rall, a virologist at Fox Chase Cancer Center, sent me the following note:
Baruch S. Blumberg, Nobel Laureate in 1976 for discovery of Hepatitis B (and the eventual development of the vaccine, which probably has saved hundreds of thousands of lives since its introduction), died this pas... Read More
Scientists from Columbia University, Georgia Institute of Technology and the University of Granada have for the first time reconstructed active enzymes from four-billion-year-old extinct organisms. By measuring the properties of these enzymes, they can examine the conditions in which the extinct... Read More
Bacteria that grow in the antennae of wasps help ward off fungal threats by secreting a 'cocktail' of antibiotics explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Read More
The meaning of the standard fecal coliform test used to monitor water quality has been called into question by a new study that identified sources of Escherichia coli bacteria that might not indicate an environmental hazard. Read More
This episode: Bacteria may help treat viral infection!
Spencer Diamond and Britt Flaherty, PhD students at UCSD, Spencer in the Susan Golden Laboratory and Britt in the James Golden Laboratory, author a post on Small Things Considered about the green potential for cyanobacteria.
"With such famous bacteria as Escherichia coli and Bacillus subtili... Read More
The part of bacterial DNA that often carries antibiotic resistance is a master at moving between different types of bacteria and adapting to widely differing bacterial species, shows a study made by a research team at the University of Gothenburg in cooperation with Chalmers University of Techno...

Maryn McKenna—my favorite "Scary Disease Girl" and author of Superbug—will be taking questions during a live chat today at Scientific American's Facebook page. The chat starts at 2:00 Eastern and lasts for a half-hour.
The chat is connected to a new article that Maryn wrote for Scientific Ame... Read More
BirdWhisperer46's YouTube channel, described as "Videos Through A Microscope," has a great collection of HD videos of microbes.
In his most recent video BirdWhisperer46 can't identify what he's captured. Can you identify the microbe(s) in this video?
Please leave a comment here or on his Y... Read More
Scientists say it's probable that they may have documented the first case of a virus contracted by a man who was bitten multiple times by insects and then sexually transmitted to his wife, according to a study published in Emerging Infectious Diseases.
Brian Foy, a biologist with the Universi... Read More
When viruses attack, one molecule more than any other fights back. Interferon triggers the activation of more than 350 genes, and despite the obvious connection, the vast majority have never been tested for antiviral properties. A team of researchers, led by scientists from Rockefeller Universit... Read More
Storing fruits and vegetables in ozone-enriched environments reduces spoilage explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Dr Ian Singleton explains how ozone treatment could be a safe, effective replacement for pesticides as it leaves no residue... Read More
Bacteria that cause pneumonia and meningitis are only able to spread when individuals are infected with flu, says a scientist reporting at the Society for General Microbiology's Spring Conference in Harrogate. The work could have implications for the management of influenza pandemics and could h... Read More
It seems the Russians are going to penetrate the oldest subglacial lake on Antarctica soon.
El podcast del Microbio Nº188 and 189 describes the famous experiment about prebiotic synthesis of organic compounds and t... Read More
A newly sequenced bacterial genome from a team led by the Department of Energy's Oak Ridge National Laboratory could contain clues as to how microorganisms produce a highly toxic form of mercury.
Methylmercury, a potent human neurotoxin, appears in the environment when certain naturally occur... Read More
