New Virus Discovered in Patients with Central Nervous System Infections: An Infection from Livestock?
WASHINGTON, DC – June 18, 2013 -- Patients in Vietnam and other locations with central nervous system infections may well be suffering from the effects of a newly discovered virus, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.
Resistance to Last-Line Antibiotic Makes Bacteria Resistant to Immune System
WASHINGTON, DC – May 21, 2013 – Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a study in mBio®, the online open-access journal of the American Society for Microbiology. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response. Colistin is a last-line drug for treating several kinds of drug-resistant infections, but colistin resistance and the drug's newfound impacts on bacterial resistance to immune attack underscore the need for newer, better antibiotics.
Intestinal Bacteria Protect against E. coli O157:H7
DENVER – CO – May 20, 2013 – A cocktail of non-pathogenic bacteria naturally occurring in the digestive tract of healthy humans can protect against a potentially lethal E. coli infection in animal models according to research presented today at the 113th General Meeting of the American Society for Microbiology. The research, conducted by scientists at the University of Michigan Medical School in Ann Arbor, could have important implications for the prevention or even treatment of this disease.
Bacterial Spare Parts Filter Antibiotic Residue from Groundwater
DENVER, CO – May 21, 2013 – Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering technology made of activated carbon. They report their results today at the 113th General Meeting of the American Society for Microbiology.
Food Laboratory Accuracy Remains a Concern
DENVER, CO – May 20, 2013 – Food microbiology laboratories continue to submit false negative results and false positive results on a routine basis. A retrospective study of nearly 40,000 proficiency test results over the past 14 years, presented today at the 113th General Meeting of the American Society for Microbiology, examined the ability of food laboratories to detect or rule out the presence of Escherichia coli O157:H7, Salmonella, Listeria monocytogenes, and Campylobacter.
