E. coli News and Research

RSS

E. coli or Escherichia coli is the name of a type of bacteria that lives in your intestines. Most types of E. coli are harmless. However, some types can make you sick and cause diarrhea. One type causes travelers' diarrhea. The worst type of E. coli causes bloody diarrhea, and can sometimes cause kidney failure and even death. These problems are most likely to occur in children and in adults with weak immune systems. You can get E. coli infections by eating foods containing the bacteria. To help avoid food poisoning and prevent infection, handle food safely. Cook meat well, wash fruits and vegetables before eating or cooking them, and avoid unpasteurized milk and juices. You can also get the infection by swallowing water in a swimming pool contaminated with human waste. Most cases of E. coli infection get better without treatment in 5 to 10 days.

Researchers identify new keys to regulation of bacterial gene expression

The cellular process of transcription, in which the enzyme RNA polymerase constructs chains of RNA from information contained in DNA, depends upon previously underappreciated sections of both the DNA promoter region and RNA polymerase

Scientists gain better understanding of Proteus mirabilis

Scientists now have inside information to use in the fight against Proteus mirabilis - a nasty bacterium that can cause kidney stones, as well as hard-to-treat urinary tract infections.

Study reveals structure of E. coli multidrug transporter protein

This new study could potentially help researchers find new ways to avoid the problem of multidrug resistance and enhance the potency of existing drug compounds.

Scientists create leaner and meaner E. coli

By stripping the E. coli genome of vast tracts of its genetic material - hundreds of apparently inconsequential genes - a team of Wisconsin researchers has created a leaner and meaner version of the bacterium that is a workhorse of modern biology and industry.

Caspase-12 antagonists could potentially be useful in the treatment of sepsis and other inflammatory and immune disorders

According to the new study, the presence of caspase-12, which appears to modulate inflammation and innate immunity in humans, increases the body's "vulnerability to bacterial infection and septic shock" while a deficiency confers strong resistance to sepsis. This new discovery suggests that caspase-12 antagonists could be a potentially useful in the treatment of sepsis and other inflammatory and immune disorders.

New discovery could help improve some forms of chemotherapy

The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell processes.

Quinolone use has surpased Sulfa antibiotics for the treatment of uncomplicated urinary tract infections in women

Sulfa drugs have traditionally been the most frequently prescribed antibiotics for women with uncomplicated UTIs. However, quinolone use has increased with the emergence of sulfa-resistant E. coli strains, which has been shown to approach 20% in some regions of the country.

Minimal genome should be twice the size

The simplest bacteria need almost twice as many genes to survive than scientists first believed, according to new research published in Nature (30 March 2006).

Patent filed for method to prevent early labor and premature delivery of low-birth-weight babies

The discovery is an incremental step in an area of obstetrics that has seen little improvement in 20 years.

Researchers find environmentally friendly ways to produce more Taxol

As the effective cancer-treatment drug Taxol enters its next generation, Michigan State University announces discoveries which point to both environmentally friendly ways to produce more Taxol, and ultimately innovations to produce a more potent second-generation drug.

Novel vaccine approach to listeria - potential protection against other intracellular bacterial pathogens

When bacterial pathogens attack the surface of a cell, vaccine-induced antibodies can mount a formidable defense and fend off the bad bugs.

Illness associated with petting zoos

While petting zoos pose a risk for gastrointestinal illness, most visitors aren't aware that simple prevention measures could prevent infection. In addition, some engage in behaviors that might increase their risk of infection according to several studies being presented this week at the International Conference on Emerging Infectious Diseases.
