Why Do Some Patients Get Infections From Cardiac Implants?
2011-10-25 03:35:37

New research suggests that some patients develop a potentially deadly blood infection from their implanted cardiac devices because bacterial cells in their bodies have gene mutations that allow them to stick to the devices. Patients with implants can develop infections because of a biofilm of persistent bacterial bugs on the surfaces of their devices. Researchers found that some strains of the bacteria, Staphylococcus aureus, have just a few genetic variants in the proteins on their...

Infectious films of Staph bacteria around an implanted cardiac device, such as a pacemaker, often force a second surgery to replace the device at a cost of up to $100,000. But not all implanted cardiac devices become infected. Now researchers from Duke University Medical Center and Ohio State University (OSU) have discovered how and why certain strains of Staphylococcus aureus (SA) bacteria, the leading cause of these device infections, have infected thousands of implanted cardiac devices....

World class scientist Professor Willem M. de Vos will explain next Monday how the microbes that are closest to our hearts — gut microbes — could underpin a new way of thinking about human biology. As well as looking at our own genes, we can now include those of our microbes in studies of human health and disease. This is a significant shift in the way we approach human biology. Gut microbes affect our health by producing vitamins, priming our immune system and contributing to...

Max Planck scientists unravel key pathway in the nitrogen cycle The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged by this process. A group of specialized bacteria perform the anammox reaction, but so far scientists have been in the dark about how these bacteria could convert ammonia to nitrogen in the complete...

Cat Urine To Power Space Travel?
2011-10-04 08:36:19

Will our next generation of space travel be powered by cat urine? Researchers from Radboud University Nijmegen in the Netherlands released a study which details the work of a particular bacterium that turns the smelly contents of your cat box (or any other type of urine) into space fuel, AFP is reporting. The results of the scientists´ work show that the bacterium anammox, first identified in the 1990´s, thrives in the absence of oxygen and transforms ammonium, the...

Max Planck researchers discover hydrogen-powered symbiotic bacteria in deep-sea hydrothermal vent mussels The search for new energy sources to power mankind's increasing needs is currently a topic of immense interest. Hydrogen-powered fuel cells are considered one of the most promising clean energy alternatives. While intensive research efforts have gone into developing ways to harness hydrogen energy to fuel our everyday lives, a natural example of a living hydrogen-powered 'fuel cell' has...

Many medical devices, ranging from artificial hip joints to dentures and catheters, can come with unwelcome guests "“ complex communities of microbial pathogens called biofilms that are resistant to the human immune system and antibiotics, thus proving a serious threat to human health. However, researchers may have a new way of looking at biofilms, thanks to a study conducted by University of Iowa biologist David Soll and his colleagues published in the Aug 2 issue of the online, open...

The Alkek Center for Metagenomics and Microbiome Research at Baylor College of Medicine, under the direction of Dr. Joseph Petrosino, builds on local expertise in the study of how the microbiota that colonize the human body (the microbiome) impact health and disease. The center is coordinating and leading research and development efforts in this area across the college, the Texas Medical Center and with collaborators from around the United States and abroad. Established in January of 2011,...
