Potential Treatment to Improve Lung Function and Antibiotic Effectiveness in Patients with Cystic Fibrosis Claremont, CA (PRWEB) October 09, 2013 Excessive viscoelastic mucus contributes to airways obstruction and progression of Cystic Fibrosis (CF) lung disease. Viscous mucus also limits mucociliary clearance and facilitates bacterial biofilm formation. Complications due to biofilm infections in CF patients continue to rise, amid diminishing therapeutic options and the expanding threat...

Novel 3-D Printing Technology Used To Build Homes For Bacteria At Microscopic Level

University of Texas at Austin By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections. In a recent experiment they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas aeruginosa, a bacteria...

The bacterium Pseudomonas aeruginosa needs iron to establish and maintain a biofilm in the lungs of cystic fibrosis patients, and therapies have been proposed to deprive the bacteria of this necessary element. However, these techniques may not work, according to a new study published in mBio®, the online open-access journal of the American Society for Microbiology, because they only target one of the two types of iron that are available in the lung. Current therapies focus on removing...

NASA Study Looks At How Spaceflight Affects Bacterial Social Networks

April Flowers for redOrbit.com - Your Universe Online Microorganisms are invisible to the naked eye. Healthy human adults have ten times as many microbial cells as human cells inside their bodies. Countless more microbes populate the environment around us, which means when astronauts launch into space, a microbial entourage follows. Communities of bacteria, known as biofilms, are often found attached to surfaces. The biofilms protect the bacteria with a slimy matrix they secrete. For...

Tiny Single-celled Organisms Have Amazingly Complicated Social Lives

Washington University in St. Louis In 2011, Nature announced that scientists had discovered a single-celled organism that is a primitive farmer. The organism, a social amoeba called Dictyostelium discoideum, picks up edible bacteria, carries them to new locations and harvests them like crops. D. discoideum enjoyed a brief spell in the media spotlight, billed as the world's smallest farmer. Now a collaboration of scientists at Washington University in St. Louis and Harvard University...

BioScience Laboratories, Inc. testing labs develops a new in-vitro biofilm model closely simulating a chronic wound for antimicrobial product testing. Bozeman, MT (PRWEB) July 29, 2013 BioScience Laboratories, Inc. (BSLI) testing labs develops new in-vitro biofilm model. The goal of this research project was to adapt the Colony/drip-flow biofilm reactor (C/DFR) by replacing the growing surface with a sample of sterilized pig skin to more closely emulate an actual wound. Chronic wounds...

Research could help in battle against infections that do not respond to powerful drugs In biology, we often think of natural selection and survival of the fittest. What about survival of the luckiest? Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly resilient communities, known as biofilms. It turns out that a lucky few bacteria become the elite cells that start the colonies, and they organize in a rich-get-richer pattern...

To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio®, the online open-access journal of the American Society for Microbiology, scientists at Emory University School of Medicine, the University of Virginia, and Universidad de las Islas Baleares in Mallorca, Spain, uncover this...

Pseudomonas aeruginosa is a common bacterium that can cause disease in animals and humans. It can be found in soil, water, skin flora, and most man-made environments throughout the world. It thrives in normal or hypoxic atmospheres; due to this it has colonized many natural and artificial environments. It can infect animals with damaged tissue or people with reduced immunity. Symptoms are generalized inflammation and sepsis. It can be fatal if colonization occurs in critical body organs,...
