Ten variants of the deadly Escherichia coli strain that hit Germany in May 2011 have been sequenced across the world. The unprecedented level of collaboration across the scientific community should give insight into how the outbreak arose, says a scientist at the Society for General Microbiology's Autumn Conference 2011. Sequencing of the bacterium started in early June at BGI, China. Their sequence was provided in draft form to the scientific community as a crowd-sourcing project. This...

Antibiotic Resistance Found In Ancient DNA
2011-09-05 04:33:02

  A team comprised primarily of Canadian researchers has discovered antibiotic resistance in the DNA of 30,000-year-old bacteria found in the Yukon permafrost, various media outlets reported last week. The scientists, who published their findings in the journal Nature, note that resistant microbes are commonly thought to have developed after the development of synthetic antibiotics over 70 years ago. However, they discovered that it is not a "modern phenomenon," but is in fact "a...

Biologists have long known that organisms from bacteria to humans use the 24 hour cycle of light and darkness to set their biological clocks. But exactly how these clocks are synchronized at the molecular level to perform the interactions within a population of cells that depend on the precise timing of circadian rhythms is less well understood. To better understand that process, biologists and bioengineers at UC San Diego created a model biological system consisting of glowing, blinking...

Reducing the risks of catching E. coli O157 in the countryside is everyone's problem. That means we should all take responsibility - individual residents and visitors, as well as farmers and government - according to researchers working on the Research Councils UK Rural Economy and Land Use Programme (RELU). E. coli O157 is the most common of the harmful strains of the bacteria and this interdisciplinary research has investigated not just its characteristics, but also how people understand...

Coriander oil has been shown to be toxic to a broad range of harmful bacteria. Its use in foods and in clinical agents could prevent food-borne illnesses and even treat antibiotic-resistant infections, according to the authors of a study published in the Journal of Medical Microbiology. The researchers from the University of Beira Interior in Portugal tested coriander oil against 12 bacterial strains, including Escherichia coli, Salmonella enterica, Bacillus cereus and meticillin-resistant...

Scientists have discovered that bacteria like E. coli and Salmonella have a sneaky way of making minor alterations to their genes to boost their chances for infection. It's a fascinating discovery made at Ohio State University, which is featured in the Aug. 14 issue of Nature Chemical Biology. This discovery shows how bacteria make tweaks in their genes, and their proteins to gain strength. The team includes research scientist Herve Roy, who joined the University of Central Florida...

LANSING, Mich., Aug. 22, 2011 /PRNewswire/ -- Neogen Corporation (Nasdaq: NEOG) has announced that its GeneSeek subsidiary is a participant in USDA-funded research that seeks to better understand the role cattle genetics may play in food contamination by the pathogen E. coli O157:H7. GeneSeek is considered the leading commercial agricultural genetics laboratory in the United States. Researchers have shown that while some cows have no E. coli O157:H7 in their systems, others present a...

In an advance in understanding Mother Nature's copy machines, motors, assembly lines and other biological nano-machines, scientists are describing how a multipurpose protein on the tail of a virus bores into bacteria like a drill bit, clears the shavings out of the hole and enlarges the hole. They report on the "Swiss Army Knife" protein, which enables the virus to pump its genetic material into and thus infect bacteria, in the Journal of the American Chemical Society. Akio Kitao and...

Sanitizing the outside of produce may not be enough to remove harmful food pathogens, according to a Purdue University study that demonstrated that Salmonella and E. coli can live inside plant tissues. E. coli 0157:H7 was present in tissues of mung bean sprouts and Salmonella in peanut seedlings after the plants' seeds were contaminated with the pathogens prior to planting. Amanda Deering, a postdoctoral researcher in food science, said seeds could be contaminated in such a manner before or...

A report by ABC's "Good Morning America" found that play areas at fast food restaurants may be harboring harmful germs and bacteria. The report said a mother who is trying to get standards in place for how restaurant play areas should be cleaned helped make the discovery. Erin Carr-Jordan, the mother who performed the research, said she found clumps of hair, rotting food and gang graffiti, among other things, when she followed her toddler into a play tube at a fast-food restaurant play area....

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...
