Research tool for turning off genes may eventually have therapeutic application

A research team based at Massachusetts General Hospital (MGH) has identified 80 new genes essential to the process of RNA interference (RNAi), a powerful new research tool for inactivating genes in plants or animals.

Genome in gut bacterium key to intestinal health

A bacterium that lives in the human gut adaptively shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates.

Child care may affect entire community's risks of infection

Any parent knows how quickly a cold or a cough can spread between children who play together. However, child care may also affect an entire community's carriage of potentially dangerous bacteria known as Streptococcus pneumoniae, according to an article in the April 1 issue of Clinical Infectious Diseases, now available online.

Children sick after zoo visit - Florida Officials investigate

Health officials in Florida report that five children are in a critical condition with kidney failure and may have picked up a rare infection at petting zoos.

Neonatal infections in hospital born babies are up to 20 times higher in developing countries

Neonatal deaths account for over one-third of the global burden of child mortality. Infections are the major cause of neonatal deaths in developing countries. (See The Lancet Neonatal Survival Series, March 2005) Data suggest that unhygienic practices in labour and delivery, and in after-birth care, put babies in the developing world at great risk of infections and death soon after birth.

Vaccine against pneumonia and invasive pneumococcal disease shows promise

A vaccine against pneumonia and invasive pneumococcal disease, a severe form of bacterial infection, can substantially reduce hospital admissions and improve the survival of children in developing countries, concludes a trial published in this week’s issue of The Lancet.

Poor oral health can affect newborn

A study published recently in the Journal of Periodontology has found that pregnant women with tooth decay are at risk for delivering Preterm Low Birth Weight (PLBW) babies.

Bacteria found in the mouth may predict pregnancy outcomes

Researchers from New York University found that certain bacteria from the mouth may be related to preterm delivery and low birthweight according to a study in the Journal of Periodontology (JOP).

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Scientists have found genetic regions that, when defective, allow the immune system to attack the pancreas

Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas -- the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings, published yesterday, March 22, in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients.

Structure of key protein in innate immune response

In a report published in the Journal of Biological Chemistry, scientists in Korea announced their elucidation of three-dimensional structure of CD14 and showed how it is perfectly suited to bind to certain bacterial products.

Scientists provide insight into the molecular mechanisms behind Listeria monocytogenes

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique.

Drug-resistant bacteria MRSA a growing threat

Infectious diseases researchers at Vanderbilt University Medical Center are noticing a significant increase in the number of infections due to Methicillin-Resistant Staphylococcus Aureus (MRSA) and the number of asymptomatic individuals who harbor the organism in their bodies.

Soft cheeses health threat to expectant mums

Cases of tuberculosis in New York City have been linked to queso fresco style cheeses which were imported from Mexico or consumed in Mexico, the cheese was found to be contaminated with Mycobacterium bovi which caused the infection.

Lack of sleep activates the body’s defence mechanisms

A lack of sleep is considered a threat situation, which activates the body’s defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations.

Drug-resistant bacteria on uncooked poultry products varies by commercial brand

The presence of drug-resistant, pathogenic bacteria on uncooked poultry products varies by commercial brand and is likely related to antibiotic use in production, according to researchers at the Johns Hopkins Bloomberg School of Public Health.

Anthrax scare in Pentagon false alarm

Two of the Pentagon mailrooms have been subjected to Anthrax tests in response to what appears to have been false alarms. The tests, which have been negative, were done a day after initial testing indicated the deadly spores might be present in some areas, prompting nearly 900 workers to take antibiotics as a precaution; it closed three mail facilities - two that serve the Pentagon and one in Washington that handles mail on its way to the military.

Search for Anthrax bacteria in Pentagon mail

Preliminary tests on mail to the Pentagon in March have shown up positive for anthrax bacteria. The mail was taken to 12 distribution nodes throughout the Pentagon from the Pentagon’s Remote Delivery Facility; it now is being moved back to a designated area in the RDF said Pentagon spokesman Glenn Flood.

Innovative computer modeling technique predicts how protein molecule behavior in response to environmental conditions

In a development that could have great significance for efforts to understand how the basic molecular machinery of life works, researchers at the University of Texas Medical Branch at Galveston (UTMB) have successfully applied an innovative computer modeling technique to predicting how protein molecules will behave in response to different environmental conditions.

New immunotherapeutic approach against anthrax

The anthrax attacks in the aftermath of September 11, 2001 in the USA have illustrated the high potential of anthrax for misuse in bio-terrorism. Dissemination of anthrax by letters led to the death of 5 people and chemotherapeutic treatment of 30,000 individuals.
