Bacteria responsible for middle ear infections, pink eye and sinusitis protect themselves from further immune attack by transporting molecules meant to destroy them away from their inner membrane target, according to a study from Nationwide Children's Hospital. The study, published in the...
While you're proudly toting your canvas "I'm Not A Plastic Bag" shopper up and down the aisles, you may want to pick up some laundry detergent, too--because that bag might be harboring more than just organic veggies. You may also be carrying around a major food safety concern. More »Post from...
Finally, E. coli is good for something other than making you regret not washing that lettuce better. Boffins at the Imperial College London have employed the bacteria as living Boolean logic gates—potential building blocks for bio-computers of the future. More »
Statins can be effective at lowering cholesterol, but they have a perplexing tendency to work for some people and not others. Gut bacteria may be the reason. A research team led by a Duke University scientist has identified three bile acids produced by gut bacteria that were evident in people...
Cells making slippery mucus provide a sticking point for disease-causing bacteria in the gut, according to a study published on October 3 in the Journal of Experimental Medicine. A foodborne bacterium called Listeria monocytogenes (sometimes found in stinky cheeses) invades the body by binding...
MyMicrobes is a new social network that'll pair you up with people who share the same gut bacteria as you. Seriously. On the surface, its a crazy idea, but when you think about it, MyMicrobes could makes sense medically. More »
Afghan patients treated at a U.S. military hospital in Afghanistan often carry multidrug-resistant (MDR) bacteria, according to a report in the September issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. The findings...
The air of two Midwestern US cities contains significant amounts of bacteria from feces, particularly dog poop, according to a new study led by the University of Colorado Boulder, published recently in the journal Applied and Environmental Microbiology. The researchers tested the air of four...
Antibiotic use in conventional animal food production in the United States has created public health concern because it has been shown to contribute to the development of antibiotic-resistant bacteria that can potentially spread to humans. A new study, led by Dr. Amy R. Sapkota of the University...
Scientists from Freie Universität Berlin and the NeuroCure Cluster of Excellence led by biochemist Volker Haucke in collaboration with colleagues from Australia and the Leibniz Institute for Molecular Pharmacology (FMP) in Berlin have developed small molecules that inhibit the internalization...
University of Minnesota researchers have discovered and received a patent for a naturally occurring lantibiotic - a peptide produced by a harmless bacteria - that could be added to food to kill harmful bacteria like salmonella, E. coli and listeria. The U of M lantibiotic is the first natural...
Scientists at Osel Inc. and the National Cancer Institute (NCI) have developed a new way to prevent HIV infection by genetically enhancing the ability of naturally occurring vaginal bacteria to block viral transmission. Bioengineered bacteria introduced into the vaginal cavity of macaques a...
Purdue University biologists identified a new way in which bacteria hijack healthy cells during infection, which could provide a target for new antibiotics. Zhao-Qing Luo, the associate professor of biological sciences who led the study, said the team discovered a new enzyme used by the...
The news coverage of the deadly EHEC bacteria outbreak in Europe came as a bombshell. Ghent University (Belgium) examined 6132 reactions of Belgian newspaper readers after reading the first news reports. As expected, people are scared and worried, but governmental trust decreases fear and leads...
The recent outbreak of an E. coli infection in Germany has resulted in serious concerns about the potential appearance of a new deadly strain of bacteria. In response to this situation, and immediately after the reports of deaths, the University Medical Centre Hamburg-Eppendorf and BGI-Shenzhen...
As partners in the international research consortium named MetaHit, scientists from the University of Copenhagen have contributed to show that an individual's intestinal bacteria flora, regardless of nationality, gender and age, organises itself in certain clusters. The cluster of intestinal...
