Bacteria have a natural ability to attach themselves to surfaces, both natural and synthetic. Once attached, they often work cooperatively to form biofilms, thin layers of bacterial colonies that can coat the surface of a medical device and introduce the risk of infection. As a result, orthopedi... Read More
Pseudomonas aeruginosa is one tough nut to crack, but a new paper sheds some light on how that cracking might be done, and adds to our knowledge of an opportunistic pathogen that strikes in homes and hospital wards every day.
Unfortunately for patients, P. aeruginosa is able to resist many ... Read More
A deadly attack of the bacteria Klebsiella Pneumoniae Carbapenemase (KPC), which has already killed 15 people and contaminated 135 Brazilian citizens has prompted around 20 hospitals to take serious measures to tackle its spread. Around 48 people are still hospitalized in 16 centers in the Feder... Read More
New findings suggesting that bacteria in the mouth and/or intestine can affect the the outcome pathogenesis of atherosclerosis and lead to new treatment strategies, reveals research from the University of Gothenburg, Sweden.
The results are to be published in the distinguished journal Proceed... Read More
Princeton engineers have developed a sensor that may revolutionize how drugs and medical devices are tested for contamination, and in the process also help ensure the survival of two species of threatened animals.
To be fair, some of the credit goes to an African frog.
In the wild, the Afr... Read More
Some bacteria react to the cold by subtly changing the chemistry of their outer wall so that it remains pliable as temperatures drop. Scientists identified a key protein in this response mechanism a few years ago, but the question of how bacteria sense cold in the first place remained a mystery.... Read More
A state-by-state analysis of vaccination data over three flu seasons contends that the number of poor children receiving the annual flu shot could be increased by up to one percentage point for every additional dollar provided to doctors to administer the vaccine.
“There is a strong correlati... Read More
Researchers from the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) and the Bindley Bioscience Center at Purdue University have developed a novel approach to automated detection and classification of harmful bacteria in food. The investigators have designed and im... Read More
When the McDonald’s down from City Hall here was burglarized a few years ago, its managers decided they needed a new security system.
It was just about that time that local police officers were offering something totally different that they hoped would stem a rising tide of robberies that oc... Read More
Increasing the amount that physicians are reimbursed by Medicaid for administering influenza shots may raise vaccination rates among poor children.
A state-by-state analysis of vaccination data over three flu seasons contends that the number of poor children receiving the annual flu shot coul... Read More
There is something very reassuring about seeing the president of the United States work to address something that you see as a significant problem. I can now state from personal experience that it is even more reassuring to observe that work in person.
I had the great privilege to be a member... Read More
Your cellphone could be a key tool in the fight against disease by relaying a telltale signature of illness to doctors and agencies monitoring new outbreaks.
"This technology is an early warning system," says Anmol Madan of the Massachusetts Institute of Technology, whose team concluded that ... Read More
Microbes matter -- perhaps more than anyone realizes -- in basic biological development and, maybe, they could be a target for reducing cancer risks, according to University of Oregon researchers.
In a study of very basic biology of zebrafish, scientists in the UO Institute of Molecular Biolo... Read More
Klassevirus, a new member of the picornavirus family, has recently been discovered in human stool and more specifically linked with pediatric diarrhea.
Researchers from the U.S. and abroad detail their findings in the October 2010 issue of the journal Clinical and Vaccine Immunology.
Initi... Read More
Analysis of H1N1 antibody levels (seroprotection rates) after the 2009 pandemic suggest that a third wave is unlikely in 2010, although adults over age 50, particularly those with chronic conditions, should be immunized for the fall flu season, states a research paper in CMAJ (Canadian Medical A...

An enzyme that keeps intestinal bacteria out of the bloodstream may also play an important role in maintaining the normal microbial population of the gastrointestinal system. Since the loss of beneficial bacteria that usually results from antibiotic therapy can sometimes lead to serious health p... Read More
For decades, factory farms have used antibiotics even in healthy animals to promote faster growth and prevent disease that could sicken livestock held in confined quarters.
The benefit: cheaper, more plentiful meat for consumers.
But a firestorm has erupted over a federal proposal recommen... Read More
Scientists have traced a bone infection to a newly described species of bacteria related to the tuberculosis pathogen. The discovery may help improve diagnosis and treatment of similar infections, according to a study.
Some rare genetic diseases can make patients susceptible to infections wit... Read More
A new approach that uses machine learning to detect harmful bacteria in food will allow for better identification of known—and unknown—classes of food pathogens.
“The sheer number of existing bacterial pathogens and their high mutation rate makes it extremely difficult to automate their detec... Read More
Scientists have identified the eight human papillomavirus (HPV) types responsible for more than 90 percent of cervical cancer cases worldwide and say they should be the targets for the next generation of vaccines.
Drugmakers GlaxoSmithKline and Merck & Co. already make vaccines against HPV st... Read More
