Probiotics Mitigate Stress in Medical Students at Exam Time

Washington, DC - May 6, 2016 - A probiotic given to medical students during the run-up to nationwide medical school examinations reduced stress among the students. “The probiotic strain, Lactobacillus casei strain Shirota can relieve many aspects of the stress response, especially gastrointestinal dysfunction,” said corresponding author Kouji Miyazaki, PhD, director of the Food Research Department of Yakult Central Institute, Tokyo, Japan. The research is published ahead of print May 6th, in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

HPV Infection Can Be Identified in Self-Collected Vaginal Swabs - Boon for Screening in Developing Countries

Washington, DC - April 29, 2016 - High risk, potentially cancer causing human papillomavirus infections are common among women in Papua New Guinea. But self sampling with vaginal swabs may provide materials that screen as accurately as the more labor-intensive approach using cervical samples obtained by clinicians. This finding is critical to developing same day screening and treatment, which is key to ensuring that women with precancerous lesions are treated in this largely unconnected (electronically) country, and in others like it. The research appeared online April 13th in the Journal of Clinical Microbiology, which is published by the American Society for Microbiology.

Proteomics Method Measures Carbon Uptake of Marine Microbes

Washington, DC – April 26, 2016 – In a paper published April 26th in mSystems, a team of researchers led by microbiologists at Oregon State University, in Corvallis, describe a successful trial of a new method of identifying the carbon uptake of specific marine bacterioplankton taxa. The technique uses proteomics – the large-scale study of proteins – to observe directly the metabolic processes of communities of microorganisms.

Danish Investigators Reduce Sugar Content of Yogurt without Reducing Sweetness

Washington, DC – April 22, 2016 –  A team from a Danish food ingredients company has manipulated the metabolic properties of yogurt-producing bacteria to sweeten the yogurt naturally, while reducing sugar in the final product. Similar manipulations have also all but eliminated lactose, so that those with lactose intolerance can enjoy the yogurt. They have accomplished all of this using microbiological methods that predate the era of genetic technologies. The research appears April 22nd in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Study: Cities have Individual Microbial Signatures

Washington, DC – April 19, 2016 – Cities have their own distinct microbial communities but these communities don’t vary much between offices located in the same city, according to a new study. The work, published this week in mSystems, an open access journal from the American Society for Microbiology, offers insight into what drives the composition of microbes in built environments.

Mothers' Milk and the Infant Gut Microbiota: An Ancient Symbiosis

Washington, DC – April 15, 2016 – Nursing infants’ gastrointestinal tracts are enriched with specific protective microbes. Mother’s milk, itself, guides the development of neonates’ gut microbiota, nourishing a very specific bacterial population that, in turn, provides nourishment and protects the child. Now a team from the University of California, Davis, has identified the compound in the milk that supplies this nourishment, and has shown that it can be obtained from cow’s milk. This work could result in using cow’s milk to provide that compound as a prebiotic for infants. The research is published ahead of print on April 15th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Cause of Maryland Food Poisoning Outbreak Traced to Asia

Washington, DC – April 6, 2016 – Vibrio parahaemolyticus caused an outbreak of food poisoning in Maryland in 2010. The pathogen strain sequenced from patients proved to be the same strain as one of those found in raw oysters from local restaurants, strong evidence that the oysters were the source of the illness. That particular strain of V. parahaemolyticus was not local, but was traced to Asia. The research is published March 18 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Targeting the Gut Microbiome to Fight Heart Disease

Washington, DC – April 5, 2016 – A compound found in red wine, resveratrol, reduces the risk of heart disease by changing the gut microbiome, according to a new study by researchers from China. The study is published in mBio, an open-access journal published by the American Society for Microbiology.

Researchers Discover New Fish Virus that Threatens Global Tilapia Stocks

Washington, D.C.—April 5, 2016—An international team of researchers has identified a new virus that attacks wild and farmed tilipia, an important source of inexpensive protein for the world’s food supply. In work published this week in mBio, an online open-access journal of the American Society for Microbiology, the team clearly shows that the Tilapia Lake Virus (TiLV) was the culprit behind mass tilapia die-offs that occurred in Ecuador and Israel in recent years. The work also provides a foundation for developing a vaccine to protect fish from TiLV.

Investigators Identify New Pneumonia Epidemic in Beijing

Washington, DC – March 31, 2016 –Mycoplasma pneumoniae infections began rising in Beijing last spring, and by December, this pathogen was found in more than half of hospitalized children suffering from pneumonia in that city, according to investigators from the Capital Institute of Pediatrics, Beijing, China. Now these investigators predict that this epidemic will likely continue well into 2016, and possibly longer. Their data may help clinicians slow the epidemic. The research is published February 24th in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology.
