New information on genetic shuffling before egg or sperm formation rewrites genetic theory

Key decisions in the genetic shuffling that occurs before eggs or sperm are formed are made earlier than thought, rewriting textbook genetics, according to recent papers from researchers at UC Davis, Harvard University and UC San Diego.

Scientists will debate E.coli and the adaption by micro-organisms to modern day drugs

This debate will centre around why humans are constantly under attack from infectious diseases such as E.coli despite medical advances in vaccinations and antibiotics, and how micro-organisms that cause disease evolve and adapt quickly to the many barriers that our bodies' anti-infection strategies and our drugs industry throw at them.

Microbiologists have characterised the DNA in bacteria responsible for vomiting

James Cook University microbiologists have characterised the DNA in bacteria responsible for one of the world's most common forms of food poisoning.

New forensic tool to detect infectious diseases

Tests for the detection of infectious diseases in North Queensland will be faster and cheaper, thanks to the purchase of new equipment in James Cook University's School of Biomedical Sciences.

University of Florida researchers have used a common gel to successfully deliver gene therapy to the diaphragm

The technique, described in the current issue of Molecular Therapy, could eventually lead to a method to correct genetic conditions in humans that cause diaphragm weakness and respiratory failure -- a leading cause of death in tens of thousands of patients with forms of muscular dystrophy, including Pompe’s disease. Thousands of Americans with muscle-weakening diseases are placed on ventilators each year, according to the Muscular Dystrophy Association.

Scientists studying vaccinia virus, a relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation

Scientists at the University of Illinois at Urbana-Champaign studying vaccinia virus, a close relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation, a crucial anti-viral immune response of host cells.

First Canadian therapeutic HIV vaccine trial

Clinicians from the McGill University Health Centre and the Centre hospitalier de l'Université de Montréal (CHUM) are participating in the first Canadian therapeutic HIV vaccine trial. Funded by a number of public and private institutions, including the Canadian Network for Vaccines and Immunotherapeutics (CANVAC) and the Canadian Institutes of Health Research, this project will begin in April.

Researchers tap modified plant viruses to ward off cervical cancer-causing infections

New vaccinations to prevent infections that lead to cervical cancer and targeted therapeutics aimed at breast cancer were examples of research highlights presented by scientists today at the 95th Annual Meeting of the American Association for Cancer Research. Scientists described advances that feed into the drug development 'pipeline,' and show strong promise for controlling existing tumors or addressing the pathogen that causes tumors.

Comparative genomics to cast new light on other spirochete microbes

Three centuries after a pioneering Dutch microbiologist first observed the spiral-shaped oral pathogen Treponema denticola, scientists have deciphered the bacterium’s entire DNA sequence and used comparative genomics to cast new light on other spirochete microbes.

British company to launch "super bug tester" into UK hospitals

MRSA is the first test to be developed from Acolyte’s BacLite® testing platform. BacLite reduces the time for identifying both the type of bacteria and, more importantly, the antibiotic sensitivity of the bacteria from the current 3-4 day standard to just 2-5 hours. This time advantage will mean clinicians will be able to treat, much more effectively, serious bacterial infections and prevent potentially fatal complications, such as sepsis and septic shock, from developing.

First US Tests of Bird-Flu Vaccine in Humans

Doctors are beginning the first test in the United States of a vaccine designed to protect people against one form of bird flu should an outbreak of the virus occur in humans. While the vaccine under study is not designed to protect against the precise bird-flu virus causing the current outbreak in poultry and in people, scientists will learn whether it protects against another strain of the virus that infects birds and people.

Scientists identify genetic changes during infection by tuberculosis

Researchers at the Center for Biomedical Inventions at UT Southwestern Medical Center at Dallas have identified the genetic changes that Mycobacterium tuberculosis, the bacterium that causes tuberculosis, undergoes during infection of a living host.

Lupus Discovery May Lead To Improved Drugs

In an important development in the treatment of lupus as well as certain cancers, scientists at the Feinberg School of Medicine at Northwestern University have discovered how autoimmune lupus T cells stave off programmed cell death and drive production of autoantibodies directed against the body’s own DNA.

Bacteria Live in the Esophagus!

The esophagus isn't merely a tube for food traveling from the mouth to the stomach, it also provides an environment for bacteria to live, according to a new study by NYU School of Medicine scientists that overturns the general belief that the esophagus is free of bacteria.
