A layer of cells that look like normal stomach lining on top of sites of stomach cancer can make it difficult to spot after removal of a Helicobacter pylori infection. In a recent study, researchers from Hiroshima University have uncovered the origin of this layer of cells: it is produced by the cancer tissue itself. […]
New research has identified a type of bacteria found in the microbiomes of elite athletes that contributes to improved capacity for exercise. These bacteria, members of the genus Veillonella, are not found in the guts of sedentary people. By taking a closer look at the bacteria, the researchers from Joslin Diabetes Center determined Veillonella metabolizes […]
Viruses, spread through mosquito bites, cause human illnesses such as dengue fever, Zika and yellow fever. A new control technique harnesses a naturally occurring bacterium called Wolbachia that blocks replication of viruses and breaks the cycle of mosquito-borne disease, according to an international team of researchers. “Wolbachia is present in around 50 percent of all […]
Researchers have discovered that humans and great apes possess a receptor on their cells that detects metabolites from bacteria commonly found in fermented foods and triggers movement of immune cells. Claudia Stäubert of the University of Leipzig and colleagues report these findings in a new study published 23rd May in PLOS Genetics. Consuming lactic acid […]
A growing number of infections — such as pneumonia, gonorrhea and tuberculosis — are becoming harder to treat, as bacteria evolve defenses against antibiotics faster than we can develop new drugs to replace them. Duke University game theorist David McAdams says faster, more accurate tests for drug-resistant infections are being developed that could, at least […]
A KAIST research team developed a microfluidic-based drug screening chip that identifies synergistic interactions between two antibiotics in eight hours. This chip can be a cell-based drug screening platform for exploring critical pharmacological patterns of antibiotic interactions, along with potential applications in screening other cell-type agents and guidance for clinical therapies. Antibiotic susceptibility testing, which […]
During the study, the workers oversaw 95 patients with contact precautions for methicillin-resistant Staphylococcus aureus, or MRSA, as well as vancomycin-resistant Enterococci and multidrug-resistant gram-negative bacilli. (iStock) Health care workers caring for infectious patients sometimes make mistakes when removing personal protective garments, resulting in contamination of clothes or equipment with antibiotic-resistant bacteria, a small study […]
Callback action: Ecoli – Iglo calls “iglo parsley” from the trade – it threatens with serious diarrhea The manufacturer “iglo Deutschland“ calls back the deep-frozen product “iglo parsley” and warns against the Eating of the relevant Batch. It can occur diarrhea, gastro-intestinal disorders and fever when eating. In the case of samples VTEC bacteria (verotoxigenic […]
People who suffer from stress-related irritable bowel syndrome have a distinctive microbial signature in their gut. However, holistic psychosomatic therapy using hypnosis is significantly more effective at treating their condition than symptomatic or probiotic treatment alone. This is the finding of studies conducted by a research group at MedUni Vienna’s Division of Gastroenterology and Hepatology. […]
Researchers at the Columbia University College of Dental Medicine have determined how F. nucleatum — a common oral bacteria often implicated in tooth decay — accelerates the growth of colon cancer. The study was published online in the journal EMBO Reports. Why it matters The findings could make it easier to identify and treat more […]
