Link between bacteria found in the mouth and the amniotic fluid of a woman in preterm labor

A 37-year-old-mother, who gave birth to a low-weight preemie at 24 weeks, exhibited the first-found link in a human between bacteria found in the mouth and the amniotic fluid of a woman in preterm labor.

Nrf2 gene findings may offer therapeutic potential for sepsis treatment

Disruption of a single gene, Nrf2, plays a critical role in regulating the body's innate immune response to sepsis and septic shock, according to a study by a research team led by Shyam Biswal, PhD, at the Johns Hopkins Bloomberg School of Public Health.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Amoebe promote persistence of epidemic strains of MRSA

Scientists in the UK have found that a type of amoeba acts as an incubator for MRSA bacteria. As amoebae are often found in healthcare environments this discovery has implications for the infection control strategies adopted by hospitals.

Scientists use bacteria found naturally in soil to produce new antibiotics in the fight against drug-resistant "Super-bugs"

Antibiotic resistance is a major problem worldwide and there is an urgent need for new antibiotics to be developed. Potential new drugs are usually made in the lab which is complicated and time-consuming.

Discovery of a gene that drives anthrax bacteria's toxic effects

A study in Cell reports the discovery of a gene that drives anthrax bacteria's toxic effects. The gene could offer a potential new target for countermeasures against the lethal toxin, according to the researchers.

Procedure cures some diabetic mice, but not in the way previously reported

Researchers attempting to reproduce a controversial 2003 mouse experiment suggestive of a cure for type 1 diabetes have found evidence that the experimental procedure does eliminate diabetic symptoms in a small fraction of the mice exposed to it.
