Duke University Bacterial test of a theory has implications for ecology and infectious disease In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting." By the end of the century, the rabbits had begun to overrun native ecosystems, reaching nationwide numbers of 600 million by 1950. They were propagating under a principle known as the Allee...

Epidemic Of E. Coli Infections Traced To One Strain Of Bacteria

George Washington University School of Public Health and Health Services Fast-evolving lethal clone spreads worldwide, according to new study published today In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys, according to a study published today in the American Society for Microbiology's open access journal mBio. Besides becoming more resistant to...

Findings may be useful in design of future drugs and catalysts The theory of evolution suggests that present-day organisms evolved from earlier life forms. At the molecular level, evolution reshaped some of the enzymes that help complete chemical processes—such as converting food into energy—in humans and all other life forms. Now a University of Iowa researcher and his colleagues describe the evolution of various forms of the enzyme “dihydrofolate reductase” as it occurred...

Bacteria Turns Nasty When Under Threat

Ranjini Raghunath for redOrbit.com - Your Universe Online E. coli is one of millions of bacterial species that live in our gut. From when we are infants, E. coli dwells peacefully in the lower intestine, maintaining a give-and-take relationship with our body – it helps the gut digest food, and gets energy to live and reproduce in return. However, the normally harmless bacterium can quickly evolve into a deadly form that can cause severe food poisoning, infection, and sometimes death....

Bacteria Grow Faster When They Feed Each Other

Max Planck Institute The division of labor is more efficient than a struggle through life without help from others – this is also true for microorganisms. Researchers from Research Group Experimental Ecology and Evolution at the Max Planck Institute for Chemical Ecology and their colleagues at the Friedrich Schiller University in Jena, Germany came to this conclusion when they performed experiments with microbes. The scientists worked with bacteria that were deficient in the production...

Sorting Good Bacteria From Bad
2013-12-02 10:39:43

Arizona State University Arizona State University scientists have developed a microfluidic chip, which can sort good germs from bad. Your intestines are home to about 100 trillion bacteria. That's more than the number of cells that comprise the entire human body. Armies of bacteria sneak into our bodies the moment we are born, uninvited but necessary guests. For the most part, these bacteria are industrious and friendly. Some of them are even beneficial, helping with digestion and...

New research from Applied Maths and PathoGenetix Inc. shows a high correlation among results from whole genome sequencing (WGS) and Genome Sequence Scanning (GSS) for strain type analysis of pathogenic E. coli. The research was presented on Tuesday at InFORM 2013, the Integrated Foodborne Outbreak Response and Management meeting. Woburn, MA and Sint-Martens-Latem, Belgium (PRWEB) November 20, 2013 PathoGenetix, Inc., a developer of an automated system for rapid bacterial identification,...

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...
