Scientists create a mosquito resistant to Type 2 dengue fever virus

Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year.

Dramatic increase in antibiotic-resistant staph infections

Staph infections resistant to antibiotics, previously only associated with hospitalization or prior contact with the healthcare system, are now widespread in the community and coming home.

Details of protein-cleaving complex key to microbe's survival may improve drug design

With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival.

Researchers gain key insights into how different types of infection-fighting T-cells survive

T-cells, or lymphocytes, are the body's natural defense mechanism against infection, directly attacking foreign bodies such as bacteria and viruses.

Genome signature tagging used to quickly identify and distinguish between pathogens and harmless microbes

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new, high-throughput technique for identifying the many species of microorganisms living in an unknown "microbial community."

Scientists show how MRSA sidesteps hospital protection measures

The MRSA 'superbug' evades many of the measures introduced to combat its spread by infecting a common single-celled organism found almost everywhere in hospital wards, according to new research published in the journal Environmental Microbiology.

Is persistent bacterial infection good for your health?

Bacteria are bad. Mothers and doctors, not to mention the cleaning product industry, repeatedly warn of their dangers. But a Stanford University School of Medicine microbiologist is raising the intriguing idea that persistent bacterial and viral infections have benefits.

Cervical cancer vaccines in development

Two preventative vaccines, Gardasil (Merck) and Cervarix (GlaxoSmithKline) that work against the Human Papilloma virus (HPV) - a sexually transmitted infection and the primary cause of cervical cancer - are gaining favorable attention.

Why people of African descent are more vulnerable to tuberculosis infection

A team of scientists has identified a cellular mechanism that may help explain the puzzle of why people of African descent are more susceptible to tuberculosis infection and why, once infected, they develop more severe states of the disease than whites.

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.

Ebola DNA vaccine shows promise

Vical Incorporated has announced that an Ebola vaccine candidate administered using Vical's proprietary DNA delivery technology was safe and well tolerated, and produced both antibody and T-cell Ebola-specific responses in all healthy volunteers who received the full 3 doses of vaccine.

Gene mutation discovered that causes a rare form of Charcot-Marie-Tooth disease

A multi-national research team that includes a Saint Louis University neurologist has discovered a gene mutation that causes a rare form of Charcot-Marie-Tooth disease, an inherited progressive nerve disorder. The findings are published in an advance online issue of Nature Genetics

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.

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.

Copper could help prevent the spread of flu infections

Copper could help prevent the spread of flu infections. Recent research at the University of Southampton shows that the Influenza A virus is virtually eradicated within six hours on copper surfaces.

Symposium on celiac disease

A scientific symposium on celiac disease, "Genetic and Immune Mechanisms in Celiac Disease," will be held at the University of California, San Diego (UCSD) School of Medicine on Friday, February 10, from 8:30 a.m. to 12 noon. The symposium, hosted by UCSD’s newly established William K. Warren Medical Research Center for Celiac Disease, will be held at the university’s Center for Molecular Genetics conference room.
