A new catheter coating that reduces bacterial attachment to its surface is being developed by scientists who are reporting their work at the Society for General Microbiology's Spring Conference in Dublin this week. The antimicrobial coating could eventually be applied to other medical implants to reduce infection which would provide significant socioeconomic benefits to the NHS. Urinary tract infections (UTIs) account for 25% of all hospital infections and cost the NHS around £125...

Yeasts which cause hard-to-treat mouth infections are killed using silver nanoparticles in the laboratory, scientists have found. These yeast infections, caused by Candida albicans and Candida glabrata target the young, old and immuno-compromised. Professor Mariana Henriques, University of Minho, and her colleagues hope to test silver nanoparticles in mouthwash and dentures as a potential preventative measure against these infections. Professor Henriques and her team, who published their...

Microorganisms play pivotal functions in nature, particularly within aquatic ecosystems. Whether in an ocean or a lake, they are key players in the food chain and the vitality of individual ecosystems. A team of researchers led by Arezoo M. Ardekani, the Rev. John Cardinal O'Hara, C.S.C., Assistant Professor of Aerospace and Mechanical Engineering at the University of Notre Dame, has shown that density stratification, a frequent feature of aquatic environments, has important ecological...

Power From Space Superbugs

Scientists from Newcastle University in the UK have incorporated the use of a microbe -- usually found high up in the Earth´s stratosphere -- and others found in the UK river estuary, to produce a new source of potential power for the world. The scientists focused their attention on the river Wear estuary, Country Durham, UK to collect and test different bacteria to see which ones had the greatest power-potential. The microbial process is well-established in sewage treatment and water...

According to the World Health Organization (WHO), one-third of the world's population is currently infected with tuberculosis bacteria. The bacteria is incredibly resistant to treatment, and despite its prevalence, very little is known about why it is so stress tolerant. But, researchers at the University of Pittsburgh have been developing a new way of culturing tuberculosis bacteria, which could lead to new insights and treatments. "This is a significant step forward in TB research," said...

Synedgen Study Shows Chitosan Derivative Reduces Risk of Food Contamination. Claremont CA (PRWEB) February 11, 2012 Claremont CA, January 24, 2012--Research conducted by Synedgen Inc. and the School of Environment, Natural Resources & Geography, at Bangor University, Bangor, UK, appears in the early view of Food Control, an international, official scientific journal of the European Federation of Food Science and Technology (EFFoST) covering microbial food safety and antimicrobial...

Manuka honey could help clear chronic wound infections and even prevent them from developing in the first place, according to a new study published in Microbiology. The findings provide further evidence for the clinical use of manuka honey to treat bacterial infections in the face of growing antibiotic resistance. Streptococcus pyogenes is a normal skin bacterium that is frequently associated with chronic (non-healing) wounds. Bacteria that infect wounds can clump together forming...

Escherichia coli bacteria thrive in the lower intestine of humans and other animals, including birds. Most are vital constituents of the healthy gut flora, but certain forms of E. coli cause a range of diseases in both humans and poultry. In this month´s issue of the journal PLoS ONE, a team of researchers at Arizona State University´s Biodesign Institute investigates disease-causing E. coli strains known as APEC (for Avian Pathogenic E. coli).  By studying circular segments...

Extracellular Matrix Identified As Source Of Spreading In Biofilms
2012-01-24 03:39:59

New research at Harvard explains how bacterial biofilms expand to form slimy mats on teeth, pipes, surgical instruments, and crops. Through experiment and mathematical analysis, researchers have shown that the extracellular matrix (ECM), a mesh of proteins and sugars that can form outside bacterial cells, creates osmotic pressure that forces biofilms to swell and spread. The ECM mechanism is so powerful that it can increase the radius of some biofilms five-fold within 24 hours. The...

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,...
