The fight to make food safer continues at a microscopic level with locally produced beef yielding encouraging early data about the effectiveness of a vaccination against dangerous E. coli bacteria.
International food marketer Cargill announced Monday the initial results of a trial for the new... Read More
Researchers have finally discovered how ivermectin, one of the most important worm-killing drugs used in both humans and animals for decades, actually works.
Ivermectin, extracted from a soil fungus in the 1970s, was originally sold under names like Heartgard to deworm pets.
Beginning in 1... Read More
Sterilization is hands down one of the most important technologies ever developed by mankind, but though we’ve known how to do battle with bacterial pathogens in places like the operating room for decades, superbugs like MRSA and Clostridium difficile persist in hospital environments, often caus...

A lighting system that kills bacteria, including superbugs such as MRSA and C difficile, has completed trials at a Glasgow hospital.
The LED technology, which can be used alongside or instead of traditional lighting, continually disinfects the air and exposed surfaces with certain violet wave... Read More
As a college biology major during the 1970s I was taught that cells in which the genetic material is separated from the cytoplasm by a nuclear membrane – such as those of animals, fungi, plants, and protists – are called eukaryotes. In contrast, the DNA of bacteria is not bounded by such a struc... Read More
The appeal of sudoku has spread to the prokaryotic world. A strain of Escherichia coli bacteria can now solve the logic puzzles – with some help from a group of students at the University of Tokyo, Japan.
"Because sudoku has simple rules, we felt that maybe bacteria could solve it for us, as ... Read More
A recently identified enzyme that can make gram-negative bacteria resistant to nearly all antibiotics is back in the news with reports of several recent cases in Canada and two in Austria.
Five Canadians have had infections with bacteria carrying the NDM-1 enzyme in the past 3 months, bringin... Read More
Researchers have developed a promising new approach to vaccination for rotavirus, a common cause of severe diarrheal disease that is responsible for approximately 500,000 deaths among children in the developing world every year.
In a study published in the November issue of Clinical and Vacci... Read More
Cholera deaths are climbing sharply in Haiti, after the infection reached the capital, Port-au-Prince, as feared. Epidemiologists who have studied other outbreaks predict that hundreds of thousands of Haitians will be stricken by the infection over the next few years as cholera takes hold in the... Read More
The microbe responsible for plague evolved in or around China more than 2,600 years ago and spread around the globe in the following millennia, according to the most comprehensive genetic study to map out the family tree of the bacterium known as Yersinia pestis.
Y. pestis' pedigree is not on... Read More
When a fisherman's body washed ashore on Australia's Queensland coast last week, police initially had no way of working out when he had died. "Unless a body is witnessed entering the water, there is no reliable method for determining the length of time that a body has been submerged," says Gemma... Read More
Researchers have designed bacteria that can produce a special glue to knit together cracks in concrete structures.
The genetically modified microbe has been programmed to swim down fine cracks in concrete and once at the bottom it produces a mixture of calcium carbonate and a bacterial glue. ... Read More
A daily dose of "friendly bacteria" could provide relief for kids suffering from the cruel pain of a chronic tummy ache, suggests a new Italian study.
Between 10 and 15 percent of school-aged children suffer from frequent stomach pain. Yet little evidence exists to date for helpful medication... Read More
Outsmarting the enemy will take a team effort. That's the message of the "Get Smart About Antibiotics" campaign from the federal Centers for Disease Control and Prevention (CDC). It aims to educate the public, doctors and agricultural producers that antibiotics need to be used more judiciously, ... Read More
Less than a month after a cholera outbreak erupted in Haiti, the infection has claimed 917 lives, AFP reported.
Haiti has long struggled to overcome political strife and poverty, but this year has been particularly hard on its citizens. In January, a massive earthquake killed an estimated 230... Read More
Gill disease may have several different causes, such as adverse environmental impacts or a variety of microorganisms. Terje M. Steinum's doctoral research has identified microorganisms that may lead to gill disease, thereby making a significant contribution to our understanding of such diseases ... Read More
A kiwifruit-killing disease is spreading throughout orchards in New Zealand, threatening to devastate the nation's billion-dollar industry.
On Monday, it was confirmed that 13 Bay of Plenty orchards had been struck with bacteria pseudomonas syringae pv actinidiae - or PSA - up from the eight ... Read More
