U of M faculty find antimicrobials altering intestinal bacteria composition in swine

05.09.2012
Researchers from the University of Minnesota's College of Veterinary Medicine, concerned about the use of antibiotics in animal production, have found that antimicrobial growth promoters administered to swine can alter the kind of bacteria present in the animal's intestinal track, resulting in an accelerated rate of growth and development in the animals.

Antibiotics are routinely administered to swine to treat illness and to promote larger, leaner animals.

The results of the study, conducted by Richard Isaacson, Ph.D., microbiologist and professor within the University of Minnesota's College of Veterinary Medicine, alongside his U of M and University of Illinois research teams, were published yesterday in the journal PNAS.

To arrive at their results, the researchers tracked the effects of the antimicrobial Tylosin. The effects were observed in the feces of commercial pigs on two farms in southwestern Minnesota.

In young pigs receiving Tylosin, the intestinal bacterial composition changed and was similar to the composition naturally accredited to an older animal. These changes are linked to improved growth and stimulate an early maturation of the immune system.

"Bacterial composition drives the ability of animals to grow and thrive by contributing to digestion and metabolism," said Isaacson. "Because the bacteria in more mature animals break down growth-promoting components in food more efficiently, younger animals are able to achieve adult size and an adult-like metabolic rate more quickly."

According to Isaacson, the question has now shifted to whether or not researchers can use this new understanding to recreate this ideal-growth composition in swine produced for human consumption without antibiotic use.

The College of Veterinary Medicine improves the health and well-being of animals and people by providing high-quality veterinary training, conducting leading-edge research, and delivering innovative veterinary services.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
