Scientists in Colorado have discovered a new approach to prevent bacterial infections from taking hold. Writing in the Journal of Medical Microbiology, Dr. Quinn Parks and colleagues describe how they used enzymes against products of the body's own defense cells to prevent Pseudomonas aeruginosa bacteria from building a protective biofilm which enables them to avoid both the body's immune mechanisms and antibiotics. 
Spit Reveals a Lot About What Lives in Your Mouth

Like it or not, your mouth is home to a thriving community of microbial life. More than six hundred different species of bacteria reside in this "microbiome," yet everyone hosts a unique set of bugs, and this could have important implications for health and disease.
McMaster researchers discover new mode of how diseases evolve

Researchers of the Michael G. DeGroote Institute for Infectious Disease Research have discovered a new way that bacteria evolve into something that can make you sick.
The finding, published in the Feb. 16 issue of the Proceedings of the National Academy of Sciences, has implications for how scientists identify and assign risk to emerging diseases in the environment.
The researchers found that bacteria can develop into illness-causing pathogens by rewiring regulatory DNA, the genetic material that controls disease-causing genes in a body
New Technique Developed for Quick Detection of Salmonella

In the hours following an outbreak of salmonella, there are many questions. And answers can be hard to find. Where did the problem start? Can it be contained? Is the sickness likely to spread?
Single Gene Lets Bacteria Jump from Host to Host
piggy submitted, created time 1 year 1 month (www.sciencedaily.com)
All life — plants, animals, people — depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease.
Now, with the help of a squid that uses a luminescent bacterium to create a predator-fooling light organ and a fish that uses a different strain of the same species of bacteria like a flashlight to illuminate the dark nooks of the reefs where it lives, scientists have found that gaining a single gene is enough for the microbe to switch host animals.
The finding, reported this week (Feb
Mooching bacteria could treat infections
sea-maid submitted, created time 1 year 1 month (www.nature.com)
Infections could be treated by adding more bacteria, say researchers who have shown that cooperation between microbes is undermined outside the bounds of the Petri dish by a few freeloaders.
Social bacteria employ a phenomenon called quorum sensing to coordinate group behavior. They release signals that are picked up by other bacteria. However, certain strains, best described as freeloaders, can detect quorum sensing signals without giving them off themselves, reaping the benefits of more virulent strains' work
Bacterial colonies control traffic flow by backtracking
Darkfrog submitted, created time 1 year 1 month (www.nature.com)
For some time, microbiologists have noticed that small populations of myxobacteria moving outward from colonies will backtrack, briefly reversing direction and moving toward the main colony before turning outward again. Counterintuitive as this may seem, this behavior seems to be how highly social bacterial control their growth. Colonies that exhibit backtracking actually grow faster than those that do not.
The researchers involved in the study suggest that these results may help us examine traffic flow patterns.
Engineered bacteria create high-energy biofuel

Researchers have designed an entire molecular assembly line in bacterial cells that pieces together a kind of alcohol that isn’t normally made by known living organisms. This alcohol could serve as a biofuel that, unlike ethanol, has a high energy density and could be used in gasoline and jet fuel
An Artist Develops a New Image--With Aid of Bacteria

Nearly five years ago, molecular biologist Edward Marcotte recalls, a high school dropout walked into his office at the University of Texas (UT), Austin, to talk shop. Despite the visitor's unconventional background, which included a stint as a video game programmer, Marcotte says that Zack Booth Simpson "won me over instantaneously. He was so clearly intelligent." They ended up talking for hours on topics such as Marcotte's use of data mining to extract information about the protein networks that control cellular functions.
Drilling Holes Through Deadly Bacteria's Kevlar-like Hide
piggy submitted, created time 1 year 2 months (www.sciencedaily.com)
To protect themselves from human defenses, disease-causing bacteria have evolved a cell wall made from a nearly impenetrable tangle of tightly woven strands. That’s made it difficult for scientists to see what goes on inside these potentially deadly organisms. But that era is now over. Rockefeller University researchers have now figured out how to drill holes through the Kevlar-like hide of gram-positive bacteria without obliterating them, and in doing so, they’ve made it possible to study, from the inside out, most of the known bacteria on the planet.

New technique is quantum leap forward in understanding proteins
piggy submitted, created time 1 year 2 months (www.eurekalert.org)
In this ongoing quest, a group of Scripps Research Institute scientists, along with colleagues from the University of California, San Diego, (UCSD) have borrowed from physics to deliver one of those research rarities—an unmitigated success. The group has devised a computational method that, with remarkable accuracy, predicts how bacterial proteins fold and interact
"Zinc Zipper" Plays Key Role in Hospital-acquired Infections
piggy submitted, created time 1 year 3 months (www.sciencedaily.com)
Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of patients in the U.S. alone.
Now, in studies that could lead to new ways to prevent this growing public health danger, a team of University of Cincinnati (UC) researchers is exploring a “zinc zipper” that holds bacterial cells together and plays a key role in such infections.
Hospital-acquired infections affect about 1
Bacteria may play big role in forming fossils

Paleontologists were stunned when fossils appearing to belong to the soft-tissued embryos of marine creatures were unearthed in Chinese sediments a decade ago
Microcapsules Act As "Roach Motel" to Harmful Bacteria

Scientists at the University of Florida and the University of New Mexico have created tiny microscopic spheres that trap and kill harmful bacteria in a manner the scientists liken to “roach motels” snaring and killing cockroaches. The research could lead to new coatings that will disinfect common surfaces, combat bioterrorism or sterilize medical devices, reducing the devices’ responsibility for an estimated 1.4 million infection-related deaths each year
Long-Term Antibiotic Use Affects "Good" Gut Bacteria

Antibiotic treatment, especially when prolonged or repeated, may have a negative impact on beneficial bacteria that live in the gut, according to a new study.
Gut bacteria play helpful roles in various aspects of human nutrition, metabolism and immune responses, experts note.
Researchers focused on the widely-used antibiotic ciprofloxacin, prescribed for a number of bacteria-caused conditions, including urinary tract infections. It has been believed that ciprofloxacin causes only modest harm to beneficial bacteria in the body.
In this study, Stanford University's Dr
