Latest Escherichia coli Stories
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 predictable.
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.
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.
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.
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.
One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics.
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...
