An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their findings this week in a study published in mBio®, the online open-access journal of the American Society for Microbiology.
New research presented last week at the American Society for Microbiology’s 2013 general meeting showed that copper can destroy norovirus. The research was conducted at the University of Southampton. That virus causes more than 20 million illnesses in the United States every year, according to the Centers for Disease Control and Prevention, and norovirus causes 267 million infections worldwide every year.
Norovirus is extremely contagious and often affects people in contained situations, such as cruise ships and retirement homes. It is spread through person-to-person contact, contact with contaminated objects, and through food and drink.
Scientists discovered that norovirus is quickly destroyed on contact with copper.
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.
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.
The study found that, on average, food laboratories report false negatives of 9.1% for Campylobacter, a bacterial foodborne illness that may cause bloody diarrhea, cramping and fever, and 4.9% for Salmonella, a bacteria that may cause diarrhea, fever and abdominal cramps sometimes leading to hospitalization or death. The false positive rate, on average, is 3.9% for Salmonella, and 2.5% for both E. coli and L. monocytogenes.
