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.

Two new research studies to help colicky infant and their parents

The wail of a colicky baby can send parents into near panic and cause sleepless nights for all. Now, two innovative research studies are being conducted at the new UT Physicians Colic Clinic at The University of Texas Health Science Center at Houston (UTHealth) to help both crying babies and their worried parents.

Viewpoints: Insurance safety net; Orszag on shift in health plans

In this country, three subjects that are guaranteed to generate a heated debate are religion, politics and, you guessed it, health insurance. Of the first two, Mark Twain observed that "people's beliefs and convictions are in almost every case gotten at second-hand."

First study to identify molecular mechanism that links inflammation to cancer epigenetics

Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.

Scientists help uncover evolutionary history of TAS2R38 bitter taste receptor gene

Long the bane of picky eaters everywhere, broccoli's taste is not just a matter of having a cultured palate; some people can easily taste a bitter compound in the vegetable that others have difficulty detecting. Now a team of Penn researchers has helped uncover the evolutionary history of one of the genes responsible for this trait.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Plasma can inactivate and prevent replication of adenoviruses

Life-threatening viruses such as HIV, SARS, hepatitis and influenza, could soon be combatted in an unusual manner as researchers have demonstrated the effectiveness of plasma for inactivating and preventing the replication of adenoviruses.

New insight into why aminoglycoside antibiotics cause deafness

Peter Steyger's research on hearing is very personal. That's because Steyger - a research scientist with the Oregon Hearing Research Center at Oregon Health & Science University - is deaf. Now Steyger has published groundbreaking research that is as personal as it gets. The study gives scientists new insight into why a specific class of antibiotics causes deafness - the same class of antibiotics that caused Steyger's deafness as a child in England 48 years ago. The study was published this month in Scientific Reports, part of the Nature Publishing Group.

Botulism toxins could be re-engineered for treating RA, asthma, psoriasis

The most poisonous substance on Earth - already used medically in small doses to treat certain nerve disorders and facial wrinkles - could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry.
