Research by University of Tennessee and Oak Ridge National Laboratory scientists has discovered that bacteria's move from sea to land may have occurred much later than thought Research by University of Tennessee, Knoxville, faculty has discovered that bacteria's move from sea to land may have occurred much later than thought. It also has revealed that the bacteria may be especially useful in bioenergy research. Igor Jouline, UT-Oak Ridge National Laboratory joint faculty professor of...

Ultimate goal: Tailings water treatment plants for all oil sands operations Alberta's oilsands have water challenges. Oilsands development uses a vast amount of water and even though it's recycled multiple times, the recycling concentrates the toxins and metals leftover from extracting and upgrading the bitumen, resulting in tailings ponds that are both a lightning rod for controversy and a significant risk to the environment. A research project underway between biologists at the...

Image 1 - Millions Of Glowing Bacteria Used To Create Living 'Neon Signs'
2011-12-19 10:49:28

[ Watch the Video ] In an example of life imitating art, biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs. Their achievement, detailed in this week's advance online issue of the journal Nature, involved attaching a fluorescent protein to the biological clocks of the bacteria, synchronizing the clocks of the thousands of bacteria within a colony, then...

A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick, according to dental researchers at Case Western Reserve University. Yiping Han, professor of periodontics at the Case Western Reserve School of Dental Medicine, made the discovery in her continued work with the Fusobacterium nucleatum bacterium, one of the most...

California-based food provider Pacific International has announced that it will voluntarily recall some 6,141 cartons of the herb cilantro after the U.S. Food and Drug Administration (FDA) alerted the company that it had detected traces of the bacteria salmonella in samples of their product. While there have been no reports of illness yet, the company has requested that anyone who purchased their cilantro between November 16 and December 10 please return it to the supermarket where they...

CDC Links Raw Flour to 2009 E. Coli Outbreak
2011-12-10 05:38:11

A 2009 E. coli outbreak that affected 77 people across 30 states may have been caused by raw flour that was an ingredient in ready-to-cook cookie dough, a new report published in the journal Clinical Infectious Disease has discovered. According to Jeannine Stein of the Los Angeles Times, the investigation, which was conducted by the Centers for Disease Control and Prevention (CDC), involved analyzing records and interviewing patients who were infected by the disease-causing agent. The...

• The study focuses on the protein Ler, which is present in the pathogenic strains of Escherichia coli that caused an outbreak of food poisoning in Germany last May. • Ler binds multiple DNA sequences, thereby activating numerous genes responsible for bacterial virulence. • The findings of the study have been published in PloS Pathogens. A team headed by scientists from the Institute for Research in Biomedicine (IRB Barcelona) reports how the protein Ler, which is...

Researchers at the University of Leeds have been studying an enzyme — called 3D — which plays a vital role in the replication of the virus behind the disease. They have found that this enzyme forms fibrous structures (or fibrils) during the replication process. What's more, they have found a molecule which can prevent these fibrils forming. The project was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and its findings have been published by the...

Streptococcus salivarius is a species of spherical, Gram-positive bacteria which colonize the mouth and upper respiratory tract of humans a few hours after birth, making further exposure to the bacteria harmless. The bacterium is an opportunistic pathogen which rarely makes its way into the bloodstream where it is associated with septicemia cases in people with neutropenia. It has different characteristics when exposed to different environmental nutrients. In the lab a SYTA plate is used...

Streptococcus oralis is a Gram positive bacterium that grows characteristically in chains. On a Wilkins-Chalgren agar plate it will form slam white colonies. It is classified as a member of the streptococcus mitis group and is found in high numbers in the oral cavity. S. oralis produce neuraminidase and an IgA protease and cannot bind α-amylase.

Enterococcus is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals. It is a main constituent of some probiotic food supplements. E. faecalis can cause life-threatening infections in humans, especially in the nosocomial environment, where the naturally high levels of antibiotic resistance found in E. faecalis contribute to its pathogenicity. It is frequently found in root canal-treated teeth in prevalence values ranging from 30% to 90% of...

Staphylococcus epidermidis is one of thirty-three known species belonging to the genus Staphylococcus. It is part of our skin flora and can also be found in the mucous membranes and in animals. It is the most common species found in laboratory test due to contamination. It is not usually pathogenic; however, patients with a compromised immune system often risk infection. Infections can be both nosocomial and community acquired and are more of a threat to hospital patients. Hospitals carry...

Serratia marcescens is a species of Gram-negative, rod-shaped bacterium in the family Enterobacteriaceae. S. marcescens is involved in nosocomial infections particularly catheter-associated bacteremia. It is commonly found in respiratory and urinarty tracts of hospitalized adults and often in the gastrointestinal system of children. It is commonly found growing in bathrooms due to its preference for damp conditions. It manifests as a pink discoloration and a slimy film feeding off...
