F. nucleatum alters endothelial integrity and allows other bacteria to invade human body

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.

Scientists identify how cells reduce tissue damage from inflammation in ALI model

Researchers at the University of Illinois at Chicago College of Medicine have found in an animal model of acute lung injury a molecular mechanism that allows cells of the immune system to reduce tissue damage from inflammation.

FIND, NUS collaborate to identify novel biomarkers for TB diagnosis

A research team from the National University of Singapore (NUS) Singapore Lipidomics Incubator (SLING) is collaborating with the Foundation for Innovative New Diagnostics (FIND) to identify novel target molecules to be employed as biomarkers for the detection of active tuberculosis.

Poor handling of oranges in squeezing machines stimulates bacterial contamination

Scientists from the University of Valencia in Spain have analysed fresh orange juice squeezed by machines in catering establishments. They have confirmed that 43% of samples exceeded the acceptable enterobacteriaceae levels laid down by legislation. The researchers recommend that oranges are handled correctly, that juicers are washed properly and that the orange juice is served immediately rather than being stored in metal jugs.

TIME examines lawsuit against U.N. alleging responsibility for cholera outbreak

"The question of who is responsible for Haiti's cholera epidemic -- the first that the Caribbean nation, the western hemisphere's poorest, has seen in a century -- has raised tempers since the first case was detected in October 2010," TIME reports in an article examining a lawsuit filed against the U.N. claiming it is responsible for bringing the disease into the country and seeking damages for cholera victims and their families.

Macrophages play a role in brown fat metabolism

Throughout the interior spaces of humans and other warm-blooded creatures is a special type of tissue known as brown fat, which may hold the secret to diets and weight-loss programs of the future.

Scientists discover how intestinal tract influences B cells to prevent infection

Researchers at the University of Toronto have found an explanation for how the intestinal tract influences a key component of the immune system to prevent infection, offering a potential clue to the cause of autoimmune disorders like rheumatoid arthritis and multiple sclerosis.

Study to establish zebrafish as functional animal model for V. cholerae

A small fish may prove useful to understanding a worldwide health problem, if a Wayne State University researcher is correct.

New cost-effective liquid solution can help fight antibiotic-resistant bacteria

According to the World Health Organization, antibiotic-resistant bacteria are one of the top three threats to human health. Patients in hospitals are especially at risk, with almost 100,000 deaths due to infection every year in the U.S. alone.

New method to design Alzheimer's antibodies

Researchers at Rensselaer Polytechnic Institute have developed a new method to design antibodies aimed at combating disease. The surprisingly simple process was used to make antibodies that neutralize the harmful protein particles that lead to Alzheimer's disease.

New guidelines for managing latent tuberculosis from CDC

The U.S. Centers for Disease Control and Prevention (CDC) has released new guidelines on treating so-called “latent” tuberculosis (TB) infection in the United States. They suggest the course of the therapy from about 9 months could be shortened to 3 months.

Shorter, effective treatment for latent TB infection

Research, led by Timothy Sterling, M.D., professor of Medicine at Vanderbilt University Medical Center, has led to an important change in CDC recommendations in the regimen for prevention of the centuries-old scourge, tuberculosis (TB).

'Disinfectants' may reduce risk of E. coli outbreaks

Some E. coli bacteria are harmless and some are dangerous from the outset. Then some become dangerous when they are subjected to viral infection. Researchers are working to find tools that will reduce the risk of this happening.

New methods speed up process of identifying harmful E. coli bacteria

New methods speed up the process of identifying the subgroup of E. coli bacteria responsible for an outbreak of illness. Swift identification may spare lives.

Paper calls for strong steps to control global crisis of antibiotic-resistant infections

Shahriar Mobashery, a University of Notre Dame researcher, is one of the coauthors of a new paper by a group of the world's leading scientists in academia and industry that calls for strong steps to be taken to control the global crisis of antibiotic resistance in bacteria. The group issued a priority list of steps that need to be taken on a global scale to resolve the crisis.

Genetically identical Salmonella appear in 2 types, each with an infective advantage

An unusual regulatory mechanism that controls the swimmer/non-swimmer option in genetically identical Salmonella also impacts the bacteria's ability to cause infection.

High gut flora protects children against allergies

High diversity and a variety of bacteria in the gut protect children against allergies as opposed to some individual bacterial genera. These are the findings of a comprehensive study of intestinal microflora (gut flora) in allergic and healthy children, which was conducted at Linköping University in Sweden.

Study identifies tertiary treatment as an important source of antibiotic resistant genes

Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That's the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor that appears in ACS' journal Environmental Science & Technology.

Considering varying extent to which genes are turned on or off can help develop personalised, predictive medicines

The vast majority of genetic disorders (schizophrenia or breast cancer, for example) have different effects in different people. Moreover, an individual carrying certain mutations can develop a disease, whereas another one with the same mutations may not. This holds true even when comparing two identical twins who have identical genomes. But why does the same mutation have different effects in different individuals?

H. pylori bacterium produces urease to neutralize gastric acid

A research team led by scientists at the Chinese University of Hong Kong is releasing study results this week showing how a bacterium, Helicobacter pylori, that causes more than half of peptic ulcers worldwide and that has been implicated in stomach cancer has managed for eons to turn the acidic environment of the human gut into one in which it can thrive.
