Role That Flagellum Plays In Helping E. Coli Colonize Rough Surfaces Revealed
2013-04-11 13:06:15

Harvard University New research from Harvard University helps to explain how waterborne bacteria can colonize rough surfaces–even those that have been designed to resist water. A team of materials scientists and microbiologists studied the gut bacterium Escherichia coli, which has many flagella that stick out in all directions. The researchers found that these tails can act as biological grappling hooks, reaching far into nanoscale crevices and latching the bacteria in place....

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli (STEC) using metagenomics (the direct sequencing of DNA extracted from microbiologically complex samples), according to a study in the April 10 issue of JAMA, a Genomics theme issue. The findings highlight the potential of this approach to identify and characterize bacterial pathogens directly from clinical specimens without laboratory culture. "The outbreak of...

Predictability is often used synonymously with “boring,” as in that story or that outcome was so predictable. For practitioners of synthetic biology seeking to engineer valuable new microbes, however, predictability is the brass ring that must be captured. Researchers with the multi-institutional partnership known as BIOFAB have become the first to grab at least a portion of this ring by unveiling a package of public domain DNA sequences and statistical models that greatly...

Evolution Of Bacteria Has Become Predictable
2013-02-20 19:24:20

Brett Smith for redOrbit.com — Your Universe Online The principles of evolution are widely accepted, but the causes and mechanisms that drive evolution are still heavily debated. In a new study published in the open access journal PLOS Biology, two researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly...

Research is the first to shed light on how harmful gut bacteria thrive in the intestine Scientists have long puzzled over why “bad” bacteria such as E. coli can thrive in the guts of those with inflammatory bowel disease (IBD), causing serious diarrhea. Now UC Davis researchers have discovered the answer–one that may be the first step toward finding new and better treatments for IBD. The researchers discovered a biological mechanism by which harmful bacteria grow, edge...

Scientists Use Sophisticated Modeling And Biotechnology To Weaken Cells By Fouling Their Metabolic Machinery
2013-02-04 11:19:01

Wyss Institute for Biologically Inspired Engineering at Harvard A team of scientists just won a battle in the war against antibiotic-resistant "superbugs" -- and only time will tell if their feat is akin to the bacterial "Battle of Gettysburg" that turns the tide toward victory. They won this particular battle, or at least gained some critical intelligence, not by designing a new antibiotic, but by interfering with the metabolism of the bacterial "bugs" — E. coli in this case...

A new metabolic engineering tool that allows fine control of gene expression level by employing synthetic small regulatory RNAs was developed to efficiently construct microbial cell factories producing desired chemicals and materials Biotechnologists have been working hard to address the climate change and limited fossil resource issues through the development of sustainable processes for the production of chemicals, fuels and materials from renewable non-food biomass. One promising...

A Kansas State University-led study has uncovered new information that helps scientists better understand the complex workings of cells in the innate immune system. The findings may also lead to new avenues in disease control and prevention. Philip Hardwidge, associate professor of diagnostic medicine and pathobiology, was the study's principal investigator. He and colleagues looked at the relationship between a bacterial protein and the innate immune system -- a system of defensive cells...

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...
