Pigs key to understanding antibiotic resistant bacteria

NSW Department of Primary Industries (NSW DPI) Immunology & Molecular Diagnostic Research Unit Team Leader, Dr James Chin, says it is commonly believed that each time an antibiotic is used only pathogens or disease-causing bacteria will be killed.

Safer fresh produce

Approximately one year after a foodborne illness outbreak caused by bacteria on fresh spinach sickened hundreds across the country, fresh produce growers and processors will meet once again with U.S. regulatory agencies to determine how best to reduce the chances of such an outbreak happening again.

Discovery of pathway that controls cell size and division

Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example.

Interferon-alpha levels may predict who might be at risk to develop lupus

Certain families produce higher levels of a specific molecule, called interferon-alpha, that primes the body's immune system to turn on, and in some cases initiate an autoimmune attack on itself, according to new research from Hospital for Special Surgery in New York City.

Scientits devise dimmer swith to regulate gene expression in mammal cells

Three Boston University biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene's function. Professor James Collins, Professor Charles Cantor and doctoral candidate Tara Deans invented the switch, which can be tuned to produce large or small quantities of protein, or none at all.

Gut bacteria boost immune response to tumors

One potent, immune-based treatment for cancer is total body irradiation (TBI). This approach first depletes the body of the population of immune cells known as lymphocytes and then involves the adoptive transfer of tumor-specific T cells to the patient.

GPs antibiotic prescribing practices are still contributing to resistance

GPs are still prescribing antibiotics for up to 80% of cases of sore throat, otitis media, upper respiratory tract infections, and sinusitis, despite the fact that official guidance warns against this practice, according to an analysis of the world's largest primary care database of consultations and prescriptions, published this week in a supplement to the Journal of Antimicrobial Chemotherapy.
