Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

Comparative effectiveness tested in diabetes study, VA records release

A study in the New England Journal of Medicine has found common surgical interventions and stents, the expensive medical devices used in bypass surgeries, are no more effective at preventing death, heart attacks and strokes in diabetic patients than less expensive drugs, the Wall Street Journal reports. The study, which included 2,368 patients, is representative of new interest in head-to-head comparisons of treatments.

New antibiotics could come from a DNA binding compound that kills bacteria in 2 minutes

A synthetic DNA binding compound has proved surprisingly effective at binding to the DNA of bacteria and killing all the bacteria it touched within two minutes.

Genomic research lays groundwork for new approaches for treating, preventing skin diseases

The health of our skin - one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface.

Research looks at ways to reduce the over-prescribing of antibiotics

Improving communications skills and the use of a simple blood test could help cut the growing number of inappropriate prescriptions of antibiotics, a joint Cardiff University trial has discovered.

Tuberculosis can evade immune response

Current research suggests that Mycobacterium tuberculosis can evade the immune response. The related report by Rahman et al, "Compartmentalization of immune responses in human tuberculosis: few CD8+ effector T cells but elevated levels of FoxP3+ regulatory T cells in the granulomatous lesions," appears in the June 2009 issue of The American Journal of Pathology.

Toddler’s mysterious meningitis trumps cancer threat

Brooklynn Spencer's mother Samantha knew something wasn't right. The 8 month old had the flu recently, but it had been four weeks. She should have been better. The Elmira mother of four pushed for blood tests in early October 2007. A few hours later, there was a knock at the door.

Aerosol delivery of antibiotics via nanoparticles

Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance.

Research points to a new way to protect kidneys threatened by insufficient blood or toxins

Better treatments for acute renal failure may be possible by blocking the mitochondrial fragmentation that occurs when kidneys don't get enough blood or are exposed to toxins, researchers at the Medical College of Georgia report in the may issue of the Journal of Clinical Investigation.

Amino acid glutamine show promise in treating stomach ulcers

Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics.

Variation of natural compound cures malaria in mice

Approximately 350 million to 500 million cases of malaria are diagnosed each year mostly in sub-Saharan Africa. While medications to prevent and treat malaria do exist, the demand for new treatments is on the rise, in part, because malaria parasites have developed a resistance to existing medications.

Swine flu preoccupies world health leaders

It is expected that the upcoming World Health Organisation's (WHO) annual assembly will be dominated this year by the emergence and spread of the new influenza virus H1N1 (swine flu).

Bacteria create aquatic superbugs in waste treatment plants

For bacteria in wastewater treatment plants, the stars align perfectly to create a hedonistic mating ground for antibiotic-resistant superbugs eventually discharged into streams and lakes.

Simple blood test proves powerful ally in the fight against malaria

Scientists at the Swedish medical university Karolinska Institutet have shown that rapid diagnostic tests (RDT) for malaria infection can provide valuable support for healthcare in low and mid-income countries in the fight against the disease.

Household bleach has a surprising new role: an effective treatment for kids' chronic eczema

Researchers from the Northwestern University Feinberg School of Medicine have discovered powerful relief in the form of diluted beach baths. It's a cheap, simple and safe treatment that drastically improves the rash as well as reduces flare-ups of eczema, which affects 17 percent of school-age children.

Key genetic mechanism a potential key to new class of antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.
