Drug dispensing robots designed to quickly prepare intravenous medications in a sterile environment can harbor dangerous bacteria, according to a report in Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. During a routine screening in 2010, personnel at Wake Forest Baptist Medical Center in North Carolina discovered Bacillus cereus bacteria in samples dispensed by their machine, the Intellifill IV. "To our knowledge, this is...

When faced with life-or-death situations, bacteria Рand maybe even human cells Рuse an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action, scientists reported here today. In a presentation at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, they said microbes "play" a version of the classic "Prisoner's Dilemma" game. Jos̩...

Extracellular Matrix Identified As Source Of Spreading In Biofilms

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...

It may not be as catchy a combination as "Miss Scarlet in the parlor with a revolver," but "polyester-rayon wipes in the field followed by saline-surfactant extraction and vortexing" is the most efficient solution to an important biological game of "Clue" deduced by researchers at the National Institute of Standards and Technology (NIST). As reported in a recent paper*, the NIST team studied different methods for collecting, extracting and quantifying microbial spores from indoor surfaces to...

HOUSTON, Feb. 14, 2011 /PRNewswire/ -- A lawsuit filed in Federal court claims that a contaminated alcohol prep pad manufactured by Triad Group, Inc. caused the sudden death of a two year old boy. The lawsuit claims Bacillus cereus bacteria from a contaminated alcohol prep pad caused a deadly meningitis infection. "This little boy had undergone a relatively simple procedure for a benign cyst," says attorney Jim Perdue, Jr. in the lawsuit. "He was recovering well until he contracted a...

Western New England College research presented at 2nd Pan-American/Iberian Meeting on Acoustics To keep soldiers in the battlefield healthy, the U.S. Army is exploring new ways to detect harmful bacteria in water. Current techniques for analyzing water in the field can take as long as 24 hours to complete, according to Bart Lipkens of Western New England College in Springfield, Massachusetts and his colleagues at Physical Sciences in Andover, Ma. They are working on an alternative technology...

Researchers at the University of California, San Diego have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signaling molecules between organisms."These are the molecules that control biology," said Pieter C. Dorrestein, PhD, associate professor at UC San Diego's Skaggs School of Pharmacy and Pharmaceutical Sciences and corresponding author of a...

An antibacterial enzyme found in human tears and other body fluids could be applied to certain foods for protection against intentional contamination with anthrax, scientists reported today at the 240th National Meeting of the American Chemical Society (ACS). "Data from this study could be used in developing safer foods for human consumption," said Saeed A. Khan, Ph.D. "The data from our study shows that lysozyme application has the potential to eliminate anthrax producing bacteria in...

Army scientists have discovered a way to "trick" the bacterium that causes anthrax into shedding its protective covering, making it easier for the body's immune system to mount a defense. The study, which appears in this month's issue of the journal MICROBIOLOGY, could lead to new approaches for treating anthrax infection. Bacillus anthracis, the causative agent of anthrax, is particularly lethal because of its protective coating, or capsule, which enables the pathogen to escape destruction...

Anthrax-causing bacteria can be engineered to shed their invisibility cloaks, making it easier for the immune system to eradicate it, according to a new study published in Microbiology. The work could lead to new measures to treat anthrax infection in the event of a biological warfare attack. Bacillus anthracis is a particularly lethal pathogen because it manages to escape recognition by the host's immune system by coating itself with a protective capsule around its surface. A key bacterial...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...

Bacillus anthracis is a Gram-positive spore-forming, rod-shaped bacterium, with a width of 1-1.2µm and a length of 3-5µm. It can grow in aerobic or anaerobic conditions. It is the only known bacterium to synthesize a protein capsule and the only pathogenic bacterium to carry its own adenylyl cyclase virulence factor. They form oval spores located centrally in a non-swollen sporangium. These spores are highly resilient and can survive extreme temperatures, low-nutrient environments, and...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
