New molecule could help in treating hospital infections

The scientists replaced a single atom from the molecular structure of vancomycin aglycon, a glycopeptide antibiotic that attacks the bacteria by inhibiting cell wall synthesis, significantly increasing the drug's spectrum of activity.

Atherosclerosis MAY be a result of bacteria from gum infection entering the bloodstream

New research is reinforcing the longstanding belief that a connection exists between periodontal disease, or severe gum inflammation, and cardiovascular disease.

New oral vaccine against Pseudomonas aeruginosa

A new oral vaccine against Pseudomonas aeruginosa, a bacterium commonly known for afflicting patients with lung dysfunction, has shown to protect healthy human volunteers from infection say researchers from England and Australia.

Animals diseases jumping to humans faster than ever before

According to scientists in the U.S. and Scotland, 75% of the 38 species of harmful organisms and viruses identified in the past 25 years are believed to have "jumped" from animals to humans.

MIT researchers capture virus in extraordinary detail

Fifty years after MIT researchers pioneered the use of electron microscopy to study viruses, MIT scientists have helped produce the most detailed images yet of the tiny infectious agents.

Oddly shaped DNA can cause DNA breaks in mammalian cells

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center.

Scientists put ehrlichiosis under the genomic spotlight

Ehrlichiosis is no star of science. This emerging disease has an awkward name, vague flu-like symptoms, and a nasty habit of being caused by bacteria that live inside ticks and flatworms.

Scientists discover how to make human collagen in the lab

It is the most important structural protein in the body, reinforcing connective tissue, bones and teeth, and forming long, fibrous cables to strengthen tendons. Collagen forms sheets of tissue that support the skin and every internal organ.

Causes of type 1 diabetes

Scientists are casting a wide, tightly woven net with the goal of catching the causes of type 1 diabetes.

Scientists investigate sugar coating that surrounds bacteria

Scientists at The University of Texas at Austin have developed a quick and simple way to investigate the sugar coating that surrounds bacteria and plays a role in infection and immunity.

Researchers unmask secrets of a tiny virus that infects bacteria

Using powerful computer tools and cryo-electron microscopes, researchers at Baylor College of Medicine unmasked the secrets of a tiny virus that infects bacteria and, in doing so, opened the door to a better understanding of a variety of viruses that infect people and animals.

Another step forward in the battle against bacterial infections

Bacterial infections can strike anyone, and they can sometimes be fatal. Because more and more bacteria are becoming resistant to the pre-eminent remedy; antibiotics; the search for new remedies against bacterial infections is in high gear.

New technology could replace time-intensive urine specimens

For the millions of people who suffer from urinary tract infections each year and the doctors who treat them, a promising new biosensor technology has been developed that may replace antiquated testing methods and save precious health care dollars.

Gut protein protects against infection and intestinal breakdown

A protein that binds to bile in the small intestine may hold the key to preventing infection and intestinal breakdown in people with conditions such as obstructive jaundice or irritable bowel syndrome, researchers at UT Southwestern Medical Center have discovered.

12 Feb 2006

Researchers define a new "first step" that initiates sepsis

A Mayo Clinic research team has challenged the accepted theory on the cause of sepsis -- a condition in which the body's cells generate fever, shock and often death. Sepsis is thought to occur when poisons from bacterial infection interfere with the cells.

Faster screening test for methicillin-resistant Staphylococcus aureus

A new screening technique for methicillin-resistant Staphylococcus aureus (MRSA) cuts by 75% the time taken to identify patients carrying MRSA and could be used to help prevent transmission of the bacteria in hospitals.

Step toward understanding the mystery surrounding drug resistance

The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing, said researchers from Baylor College of Medicine in a report that appears online in the Proceedings of the National Academy of Sciences.

Key genes identified that enable tuberculosis infection to spread

Scientists in India, led by a Howard Hughes Medical Institute (HHMI) international research scholar, have identified five key genes that enable Mycobacterium tuberculosis to acquire the iron it needs to sustain growth and promote infection

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.
