Probiotic bacteria could help treat Crohn's disease

01.04.2011
New research suggests that infection with a probiotic strain of E. coli bacteria could help treat an reduce the negative effects of another E. coli infection that may be associated with Crohn's disease. Researchrs from the University of Auckland, New Zealand publish their results in the April 2011 issue of the journal Applied and Environmental Microbiology.

Crohn's disease is a common chronic disorder that affects the gastrointestinal tract and is believed to develop as a result of an aberrant immune response to intestinal microbes in a genetically susceptible host. Over the last decade, high levels of adherent invasive E. coli (AIEC) have been reported. One study isolated the bacteria in 36% of Crohn's sufferers compared to just 6% of controls.

Since Crohn's disease is a clinical subtype of inflammatory bowel disease (IBD) and others have reported successful treatment of IBC with the probiotic E. coli Nissle 1917 (EcN), the researchers investigated the impact EcN might have on an already established infection with AIEC in cell cultures mimicking those found in the lining of the intestines.

They found that treatment with EcN not only helped prevent the AIEC reference strain LF82 from invading the cells and establishing infection, it also appears to modulate production of immune proteins that cause inflammation.

"This study is the first to our knowledge to show that EcN can reduce some of the negative effects associated with the strain LF82 in an already established AIEC infection and emphasizes the potential of EcN in IBD treatment. In particular the use of this probiotic could be of interest in CD patients harboring pathogenic AIEC," write the researchers.

The American Society for Microbiology, headquartered in Washington, D.C., is the largest single life science association, with 40,000 members worldwide. Its members work in educational, research, industrial, and government settings on issues such as the environment, the prevention and treatment of infectious diseases, laboratory and diagnostic medicine, and food and water safety. The ASM's mission is to gain a better understanding of basic life processes and to promote the application of this knowledge for improved health and economic and environmental well-being.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
