The zeta toxins are a family of proteins that are normally present within various pathogenic bacteria and can mysteriously trigger suicide when the cells undergo stress. A team led by Anton Meinhart at the Max Planck Institute for Medical Research in Heidelberg has now found the mechanism underl... Read More
In this week's PLoS Medicine, and to coincide with World TB Day, Madhukar Pai from McGill University in Montreal, Canada and colleagues introduce the BCG World Atlas, an open access, user friendly website for TB clinicians to discern global BCG vaccination policies and practices and improve the ...

Each of us carries a unique collection of trillions of friendly microbes in our intestines that helps break down food our bodies otherwise couldn't digest.
This relationship between humans and their microbes is generally a healthy one, but changes to the mix of microbes in the digestive tract... Read More
Stress can change the balance of bacteria that naturally live in the gut, according to research published this month in the journal Brain, Behavior, and Immunity.
"These bacteria affect immune function, and may help explain why stress dysregulates the immune response," said lead researcher Mi... Read More
Five years ago, large numbers of farmers in central China began falling victim to an mysterious disease marked by high fever, gastrointestinal disorder and an appalling mortality rate — as high as 30 percent in initial reports. Investigators from the Chinese Center for Disease Control and Preven... Read More
Investigators from Japan show in vitro that the bacterium Streptococcus salivarius, a non-biofilm forming, and otherwise harmless inhabitant of the human mouth, actually inhibits the formation of dental biofilms, otherwise known as plaque. Two enzymes this bacteria produces are responsible for t... Read More
The reanalysis of a 1958 experiment suggests that volcanic eruptions may have spawned the amino acids that contributed to the rise of life on earth. Scientific debates don't get much hotter than the one surrounding the origin of organic molecules at the dawn of life on Earth. New findings, based... Read More
Recent research aboard the Space Shuttle is giving scientists a better understanding of how infectious disease occurs in space and could someday improve astronaut health and provide novel treatments for people on Earth. The research involves an opportunistic pathogen known as Pseudomonas aerugin... Read More
In analyzing malaria mosquitoes in sub-Saharan Africa, a Cornell-led team of researchers finds evidence of two very different evolutionary paths in the immune systems of neighboring mosquito groups. Genes in animal immune systems may evolve in one of two main ways in the constant fight against p... Read More
A compound that is an active ingredient in plants commonly used in Chinese medicine prevents biofilm formation on polystyrene and polycarbonate surfaces by Staphylococcus aureus. The research suggests that this compound, 1,2,3,4,6-Penta-O-galloyl-beta-D-glucopyranose (PGG) is highly promising fo... Read More
In early summer 2008 Timothy Walsh of Cardiff University in Wales got an e-mail from Christian Giske, an acquaintance who is a physician on the faculty of Sweden’s Karolinska Institute. Giske had been treating a 59-year-old man hospitalized that past January in Örebro, a small city about 100 mil... Read More
A joint study by local oyster growers and researchers at the Virginia Institute of Marine Science shows that moving farmed oysters into saltier waters just prior to harvest nearly eliminates the presence of a bacterium that can sicken humans.
The findings—reported by VIMS professors Kim Reece... Read More
A team of scientists from the University of Oxford, U.K. have taken lessons from Adam Smith and Charles Darwin to devise a new strategy that could one day slow, possibly even prevent, the spread of drug-resistant bacteria. In a new research report published in the March 2011 issue of Genetics, t... Read More
For the upcoming 12th Symposium on Aquatic Microbial Ecology (SAME 12) held in Rostock/Warnemünde (Germany) from August 28th to September 2nd 2011 the registration and abstract submission has now started.
The conference will take place in the “AudiMax” lecture hall on the Campus of the Unive... Read More
The blog for the USA Science and Engineering Festival has a post about the importance of microbes and the expanding roles of microbiologists, plus it features two MicrobeWorld videos.
"The average science student knows that microbiology is the study of bacteria and other microor... Read More
Step far enough back from the tree of life and it begins to look quite simple. At its heart are just three stout branches, representing the three domains of life: bacteria, archaea and eukaryotes. But that's too simple, according to a band of biologists who believe we may be on the verge of disc... Read More
Google Ventures has led a $20 million financing round in CoolPlanetBiofuels, a Southern California start-up that is developing mobile refineries to turn wood chips, agriculture waste and other biomass into biofuels.
CoolPlanetBiofuels, an 18-month-old company, has also attracted the attention... Read More
State and local environmental crews have scoured the beaches along the Merrimack River and Atlantic Ocean on the North Shore in search of several hundred thousand sewage treatment disks from a New Hampshire wastewater plant.
The 2-inch diameter white objects, which may contain dangerous bacte... Read More
The new testing tool detects four of the most common contaminants in drinks; heterotrophic count, coliform, yeast and mold, and enterobacteriaceae.
3M developed the tool as an alternative to agar petri dishes. The company claims that the traditional approach of manufacturers using their own a... Read More
Imagine the cool ocean breeze, the sunshine warming your face, the sand between your toes - and a body of brown water infested with harmful algal blooms.
