By manipulating the way bacteria "talk" to each other, researchers at Texas A&M University have achieved an unprecedented degree of control over the formation and dispersal of biofilms — a finding with potentially significant health and industrial applications, particularly to bioreactor technology. Working with E. coli bacteria, Professor Thomas K. Wood and Associate Professor Arul Jayaraman of the university's Artie McFerrin Department of Chemical Engineering have employed...

For decades, scientists and farmers have attempted to understand how a bacterial pathogen continues to damage tomatoes despite numerous agricultural attempts to control its spread. Pseudomonas syringae pv. tomato is the causative agent of bacterial speck disease of tomato (Solanum lycopersicum), a disease that occurs worldwide and causes severe reduction in fruit yield and quality, particularly during cold and wet springs. In the spring of 2010, for example, an outbreak in Florida and...

Image 1 - 'Vampire' Bacteria Has Potential As Living Antibiotic

A vampire-like bacteria that leeches onto specific other bacteria — including certain human pathogens — has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates. The bacterium, Micavibrio aeruginosavorus, was discovered to inhabit wastewater nearly 30 years ago, but has not been extensively studied because it is difficult to culture and investigate using traditional microbiology techniques. However, biologists in the University...

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...

Pseudomonas deploys a toxin delivery machine to breach cell walls of rivals without hurting itself Microbiologists have uncovered a sneaky trick by the bacterium Pseudomonas aeruginosa to oust rivals. It deploys a toxin delivery machine to breach cell walls of competitors without hurting itself. Its means of attack helps it survive in the outside environment and may even help it cause infection. P. aeruginosa is a common bacterium that lives in soil, and also an opportunistic pathogen best...

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...

MONMOUTH JUNCTION, N.J., June 10, 2011 /PRNewswire/ -- Insmed Incorporated (Nasdaq CM: INSM), a biopharmaceutical company, today announced positive data through six treatment cycles (72 weeks total duration) of its Phase 2 clinical trial program for ARIKACE® (liposomal amikacin for inhalation) in cystic fibrosis (CF) patients with Pseudomonas lung infections. The data were presented at the 34th European Cystic Fibrosis Conference in Hamburg, Germany, by Predrag Minic,...

As it turns out, humans aren't the only organisms that turn to caffeine for a pick-me-up. University of Iowa scientists have identified four different bacteria that actually can live on caffeine. One of them, known as Pseudomonas putida CBB5, was found in a flowerbed outside a UI research laboratory. The research team says the discovery -- and the new understanding of how the process works -- could in the future allow scientists to convert waste from leftover coffee, tea and even chocolate...

A new bacterium that uses caffeine for food has been discovered by a doctoral student at the University of Iowa. The bacterium uses newly discovered digestive enzymes to break down the caffeine, which allows it to live and grow. "We have isolated a new caffeine-degrading bacterium, Pseudomonas putida CBB5, which breaks caffeine down into carbon dioxide and ammonia," says Ryan Summers, who presents his research today at the 111th General Meeting of the American Society for Microbiology in New...

VIENNA, April 1, 2011 /PRNewswire/ -- Today Intercell AG (VSE: ICLL) announced that it has agreed with Novartis to advance Intercell's investigational Pseudomonas aeruginosa vaccine into a confirmatory clinical efficacy trial in ventilated ICU (Intensive Care Unit) patients. The planned double blind study is powered to show a clinically meaningful and statistically significant reduction in overall mortality between the vaccine and control group and envisages enrolling about 800 subjects....

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,...
