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.

Link between cardiovascular disease and periodontal bacteria

Researchers report this week that older adults who have higher proportions of four periodontal-disease-causing bacteria inhabiting their mouths also tend to have thicker carotid arteries, a strong predictor of stroke and heart attack.

Washing hands with soap and water best protection against disease-causing viruses

The largest, most comprehensive study ever done comparing the effectiveness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one's hands with good old-fashioned soap and water.

Researchers identify biochemical target that could lead to a new class of antibiotics to fight TB

A worldwide health problem, tuberculosis kills more people than any other bacterial infection. The World Health Organization estimates that two billion people are infected with TB, and that two million people die each year from the disease.

Research shows how bacteria respond when subjected to environmental alterations in space stations

An article in Journal of Applied Microbiology investigates how bacteria respond when they are subjected to environmental alterations, such as those of space stations, which feature lowered effects of gravity.

DNA ejection from single phage particles

Studying phage, a primitive class of virus that infects bacteria by injecting its genomic DNA into host cells, researchers have gained insight into the driving force behind this poorly understood injection process, which has been proposed in the past to occur through the release of pressure accumulated within the viral particle itself.

Air Genome Project to sample air using whole genome shotgun sequencing

The J. Craig Venter Institute is launching a pilot project to better understand the diversity of microbes in urban air. In addition to more deeply characterizing the microbes we breathe every day, researchers anticipate that the results will provide information vital to designing systems that detect potentially dangerous biological substances in the air.

Proteins link cellular aging and response to calorie restriction

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce.

Genome clues to amoebic dysentery

Each year, there are an estimated 50 million cases of amoebic dysentery, causing up to 100,000 deaths, mostly in developing countries. On Thursday 24 February 2005, researchers at the Wellcome Trust Sanger Institute and their colleagues reported in Nature magazine the genome sequence of the parasite that causes the disease, Entamoeba histolytica.

Scientists find protein that could unlock the secret to more effective treatment of TB

In a study published on 1st March 2005 in Nature Structural & Molecular Biology, a combined team discovered the structure of a protein known as resuscitation promoting factor (Rpf). Five versions of the Rpf protein exist in TB bacteria. The paper’s unveiling of the molecular structure of Rpf could be crucial to the treatment of TB in the future.

Up to 500,000 Americans will develop lupus-related kidney disease

According to the Lupus Foundation of America, an estimated 300,000 to 500,000 Americans with the autoimmune disease lupus eventually will develop lupus-related kidney disease, known as lupus nephritis. Lupus nephritis is one of the most serious manifestations of lupus and can lead to serious health problems, kidney failure, disability or death.
