Vaccination would curb Haitian cholera

Vaccination would help to address the current cholera epidemic in Haiti, say US researchers. They believe the measure should be deployed alongside efforts to provide clean drinking water and improved sewage treatment. At present, no such vaccination is planned. Experts disagree over whether vacc... Read More

Lesser-known Escherichia coli types targeted in food safety research

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

Gram-positive Enterococcus sp. bacteria

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

Overcoming resistance

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

Baruch S. Blumberg, MD, 1925-2011

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

Researchers resurrect ancient enzymes to reveal conditions of early life on Earth

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 in wasp antennae produce antibiotic cocktails

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

Study provides new way to classify E. coli bacteria and test for fecal contamination

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

Antibiotic resistance spreads rapidly between bacteria

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...

Chat with Maryn McKenna about antibiotic resistance today

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

Can you identify this round microbe? (video)

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

Man contracts insect-borne virus and sexually transmits to wife

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.

Big Picture Of How Interferon-Induced Genes Launch Antiviral Defenses Revealed

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

Ozone reduces fungal spoilage of fruits and vegetables

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

Flu helps spread pneumonia

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
