Bovine colostrum and fermented cabbage can help restrict infections

15.09.2008
Researcher Susanna Rokka of MTT Agrifood Research Finland has shown in her doctoral thesis that antibodies extracted from bovine colostrum as well as lactobacilli extracted from fermented cabbage and other sources prevent the action of pathogenic bacteria in the gastrointestinal tract.

Rokka studied the effects of bovine colostrum, of specific antibodies produced in the bovine colostrum by vaccinating cows, and of lactobacilli on infections in the gastrointestinal tract. The infections studied were gastritis, dental caries and the E. coli infection in calves. Helicobacter pylori, which causes gastritis and gastric ulcer, is also often the cause of stomach cancer.

Vaccinating cows with specific pathogens can create antibodies in their blood which are then transferred to the cow’s milk as well. Concentrations are particularly high in colostrum, which is produced by the cow immediately after parturition.

COLOSTRUM SHOWN TO TACKLE HELICOBACTERIA AND DENTAL CARIES

In tests, an immune colostrum preparation could prevent helicobacter infection in mice. The preparation could not cure an existing infection but, combined with an antibiotic, it reduced inflammation and the number of helicobacteria in the gastrointestinal tract more efficiently than an antibiotic alone. Colostrum also promoted the elimination of colibacteria in the bloodstream of calves.

The research also investigated how lactobacilli operate in gastrointestinal infections. It was found that lactobacilli combined with an immune milk preparation effectively prevented Streptococcus mutans, the root cause of dental caries, from adhering to tooth surface, and Helicobacter pylori from adhering to the human gastric cells. Both were found to also relieve inflammation.

The study also revealed that in milk fermented with lactobacilli LGG, antibodies for caries remained functional for a long time.

Doctoral thesis by Susanna Rokka, MSc in Biochemistry: "Bovine colostral antibodies and selected lactobacilli as means to control gastrointestinal infection" will be examined on September 26th 2008 at the University of Turku in Finland. The opponent will be Professor Harsharn Gill from Australia and the custos will be Professor Heikki Kallio from Finland.

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...

Im Focus: A transistor of graphene nanoribbons

Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."

Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
