Sugar can silence a key protein required for colonization by a gut bacterium associated with lean and healthy individuals, according to a new Yale study published in the journal Proceedings of the National Academy of Sciences.
Researchers at Osaka University have discovered that polymyxin E-resistant Escherichia coli is widely prevalent among people living in rural Vietnam. Polymyxin is an antibiotic that is used to prevent the growth of Gram-negative bacteria such as E.coli and Pseudomonas aeruginosa . It is one of a few remaining drugs that can treat multidrug-resistant bacteria and is categorized as a last-resort antibiotic by the World Health Organization.
A team of researchers with members from the Netherlands and the U.S. has found differences in the numbers of gut microbes for patients with inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).
In their paper published in the journal Science Translational Medicine the group describes how they sequenced the genome of gut microbes in patients with bowel problems and what they found.
In a new report published in Expert Review of Vaccines, the Global Meningococcal Initiative (GMI) -a leading group of scientists, doctors, and public health officials – warns that the incidence of meningococcal meningitis strains with resistance to traditional antibiotics is at risk of increasing worldwide.
Recent breakthroughs in immunotherapy are making a huge difference in treating some forms of cancer, especially metastatic cancer. But breast cancer has proven a tricky foe for this new therapy, and an interdisciplinary team of FSU researchers is now a little bit closer to figuring out why.
Face masks appear to provide important protection against drug-resistant Staphylococcus aureus bacteria for hog farm workers and for household members to whom they might otherwise transmit the bacteria, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.
In light of the growing antibiotic resistance, the usage of plant-derived antimicrobial agents could serve as an effective alternative treatment against oral infections. This study aimed to investigate the antimicrobial and antibiofilm activity of Mediterranean herb extracts against representative oral microorganisms.
E.coli, the notorious bug associated with severe food poisoning and usually caught from undercooked meat, is a common concern for anyone cooking over the festive period.
The married professors were spending their Thanksgiving holiday in Egypt when the husband, Thomas L. Patterson, Ph.D., got very sick very quickly, experiencing fever, nausea and a racing heartbeat. By the time Patterson was accurately diagnosed with a highly multi-drug resistant bacterial infection, he was near death. His wife, Steffanie Strathdee, Ph.D., promised to leave no stone unturned.
Move over Bifidobacterium and Lactobacillus. There's a new health-promoting gut bacterium in town, and it's called Akkermansia muciniphila. You will not find its benefits at the bottom of a yogurt cup. But a new study has identified more than one way to nurture its growth in the gut and offered evidence that it may maintain—and even restore—health as we age.
An ongoing global outbreak of Mycobacterium chimaera infections is associated with contamination of a widely used surgical device, the 3T heater-cooler unit, researchers report. The outbreak began in Switzerland in 2011, and since then the Swiss Chimaera Taskforce estimates an annual incidence of 156-282 cases for the Ten major valve replacement markets, with 51-80 cases in the U.S. alone.
In a new study published in the Journal of Experimental Medicine, scientists at the University of Notre Dame have discovered that the pathogen Mycobacterium tuberculosis (MTB) releases RNA into infected cells. This RNA stimulates the production of a compound known as interferon beta that appears to support the growth of the pathogen.
