Two UC San Diego chemists have discovered the most naturally variable protein known to date in a bacterium that is a key player in the formation of dental plaque.The chemists, who announced their discovery in this week's early online edition of the journal Proceedings of the National Academy of Sciences, say they believe the extreme variability of the protein they discovered in the bacterium Treponema denticola evolved to adhere to the hundreds of different kinds of other bacteria that...

New parents have one more reason to pay attention to the oral health of their toothless babies. A recent University of Illinois study confirms the presence of bacteria associated with early childhood caries (ECC) in infant saliva. ECC is a virulent form of caries, more commonly known as tooth decay or a cavity. Cavities are the most prevalent infectious disease in U.S. children, according to the Centers for Disease Control and Prevention. "By the time a child reaches kindergarten, 40 percent...

The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst. Their findings reported in the Aug. 7 advance online issue of Nature Nanotechnology may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state...

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...

A revolutionary biodegradable pellet which slowly releases antibiotics into the middle ear could transform the lives of thousands of children who suffer from glue ear. Scientists at The University of Nottingham have developed the tiny controlled-release antibiotic pellet which can be implanted in the middle ear during surgery to fit grommets, or small ventilation tubes. Over a period of three weeks it will release effective quantities of antibiotics to target any infection which can, in up to...

Study could help researchers develop anti-bacterial surfaces Jacinta Conrad, an assistant professor of chemical and biomolecular engineering at the University of Houston, likens her research into how bacteria move to "tracking bright spots on a dark background." Using a digital camera affixed to a microscope, Conrad and her collaborators videotape hours of moving bacteria. They then analyze these tens of thousands of images to determine exactly how they cross surfaces before forming biofilms,...

Pseudomonas aeruginosa targets opponents' cell walls and immunizes itself against its own weapons When competing for food and resources, bacteria employ elaborate strategies to keep rival cells at bay. Scientists have now identified a pathway that allows disease-causing bacteria to attack other bacterial cells by breaking down their cell wall. Pseudomonas aeruginosa is a type of bacteria readily found in everyday environments. It easily forms colonies in a wide variety of settings, including...

Bacteria use various appendages to move across surfaces prior to forming multicellular bacterial biofilms. Some species display a particularly jerky form of movement known as "twitching" motility, which is made possible by hairlike structures on their surface called type IV pili, or TFP. "TFP act like Batman's grappling hooks," said Gerard Wong, a professor of bioengineering and of chemistry and biochemistry at the UCLA Henry Samueli School of Engineering and Applied Science and the...

PITTSBURGH, June 17, 2011 /PRNewswire/ -- Carnegie Mellon University's Kelvin B. Gregory and Philip R. LeDuc have created the world's smallest fuel cell powered by bacteria. Future versions of the biology-powered fuel cell could be used for self-powered sensing devices in remote locations where batteries are impractical, such as deep ocean or geological environments.

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,...
