Oestrogen promotes presence of 'mucoid' form of P. aeruginosa in women with CF

Researchers from the Respiratory Research Division of the Department of Medicine, Royal College of Surgeons in Ireland (RCSI) have published a study which represents a major breakthrough in understanding why females with cystic fibrosis do worse than males.

New method can screen for bacterial genes that are expressed during meningitis

Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromised patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

Childhood obesity risk may be increased by caesarean section delivery

Caesarean section delivery may double the risk of subsequent childhood obesity, finds research published online in the Archives of Disease in Childhood.

COPD patients with P. aeruginosa infection more likely to have poor clinical outcomes

Patients with chronic obstructive pulmonary disease (COPD) who become infected with the bacterium Pseudomonas aerguinosa are more likely to have worse clinical outcomes and experience more hospitalizations during the course of their disease than COPD patients who are not infected, according to researchers from Buffalo, N.Y.

PTH boosts AMPs to fend off infection-causing microbes

Antimicrobial peptides (AMPs) are molecules produced in the skin to fend off infection-causing microbes. Vitamin D has been credited with a role in their production and in the body's overall immune response, but scientists at the University of California, San Diego School of Medicine say a hormone previously associated only with maintaining calcium homeostasis and bone health is also critical, boosting AMP expression when dietary vitamin D levels are inadequate.

Azithromycin can be effective treatment option for patients with BOS

Researchers in the United Kingdom have determined that azithromycin, a broad-spectrum antibiotic that also has anti-inflammatory properties, can be an effective treatment option for patients suffering from bronchiolitis obliterans syndrome (BOS), a life-threatening complication that occurs in the majority of patients following lung transplantation.

Acne pills can cause eye infections

Millions of teenagers suffer from acne, and they deal with the embarrassing skin blemishes by taking popular prescription medications such as Accutane or Roaccutane. Now, however, research from Tel Aviv University shows that these pills can also cause eye infections such as conjunctivitis (pink eye) or sties.

USPTO issues patent to MicuRx’s MRX-I antibacterial agent

MicuRx Pharmaceuticals, Inc., a privately-held biopharmaceutical company developing next-generation antibiotics, today announced that the U.S. Patent and Trademark Office (USPTO) issued a composition of matter patent covering its clinical candidate, MRX-I. MRX-I is a novel antibacterial oxazolidinone that targets infections due to multi-drug resistant Gram-positive pathogens.

Proper care of diabetic foot infections can save limbs, lives

Diabetic foot infections are an increasingly common problem, but proper care can save limbs and, ultimately, lives, suggest new guidelines released by the Infectious Diseases Society of America.

Scientists determine genetic sequences of all 12 vancomycin-resistant staph strains

National Institutes of Health-funded scientists have determined the genetic sequences of all 12 available strains of Staphylococcus aureus bacteria resistant to vancomycin-an antibiotic of last resort-and have demonstrated that resistance arose independently in each strain after it acquired a specific bit of genetic material called transposon Tn1546

Scientists trace origin and development of vancomycin-resistant S. aureus

National Institutes of Health-funded scientists have determined the genome sequences of a dozen strains of Staphylococcus aureus bacteria known to be resistant to vancomycin, an antibiotic of last resort. The researchers demonstrated -that resistance arose independently in each strain, and identified shared features among the strains that may have helped them acquire vancomycin resistance and evade human immune defenses.

Researchers identify novel biomarkers that could confirm exposure to radiation

Researchers at the Medical College of Wisconsin have identified novel biomarkers that could be used to confirm exposure to damaging radiation in large groups of people potentially exposed to unknown and variable doses for the purpose of triage and treatment.

Microfluidic chip can diagnose latent TB

Biomedical engineers at UC Davis have developed a microfluidic chip to test for latent tuberculosis. They hope the test will be cheaper, faster and more reliable than current testing for the disease.

Combination of vitamin D and BCG vaccine improves bladder cancer survival

The tuberculosis vaccine is often used as a treatment for bladder cancer, and adding vitamin D might improve the vaccine's effectiveness, according to new research from the University of Rochester Medical Center presented today at the American Urological Association annual meeting.

New strategy can reactivate genes that cause cancer tumors to shrink and die

A team of scientists has developed a promising new strategy for "reactivating" genes that cause cancer tumors to shrink and die. The researchers hope that their discovery will aid in the development of an innovative anti-cancer drug that effectively targets unhealthy, cancerous tissue without damaging healthy, non-cancerous tissue and vital organs.

First insight into links between microbes and developing infant

A new multi-university study reports that differences in bacterial colonization of the infant gut in formula-fed and breast-fed babies lead to changes in the expression of genes involved in the infant's immune system.

Scientists decipher structure of bacterial injection needles at atomic resolution

The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response.
