Black Death Genome Could Reveal Secrets of Ancient And Modern Pathogens
2011-10-13 04:32:16

Scientists have successfully mapped the complete genome of the Black Death - the bubonic plague that wiped out 50 million Europeans between 1347 and 1351 and remains one of the most severe epidemics of all time - various news agencies reported on Wednesday. According to Kate Kelland of Reuters, an international team of researchers extracted and purified DNA from the remains from victims buried in the so-called plague pits of London. "Building on previous research which showed that a...

Raw Sewage Is Home To Millions Of Undescribed Viruses
2011-10-04 10:53:53

Biologists have described only a few thousand different viruses so far, but a new study reveals a vast world of unseen viral diversity that exists right under our noses. A paper to be published Tuesday, October 4 in the online journal mBio® explores ordinary raw sewage and finds that it is home to thousands of novel, undiscovered viruses, some of which could relate to human health. Viruses are everywhere: every moment of every day, humans are exposed to viruses on surfaces, in foods,...

How diseases are transmitted among humans, other animals, the environment is focus New research aimed at controlling the transmission of diseases among humans, other animals and the environment is being made possible by grants from a collaboration among U.S. and U.K. funding agencies. By improving our understanding of the factors affecting disease transmission, the projects will help produce models to predict and control outbreaks. Funding is from the U.S. National Science Foundation...

Researchers at the University of Toronto have developed a therapy for a potentially deadly type of infection common in catheters, artificial joints and other "in-dwelling" medical devices. Their findings appear in the Open Access Journal PLoS Pathogens on September 8th. The therapy targets fungal infections, which are hard to treat in such devices because they are composed of biofilms–complex groupings of cells that attach to surfaces. Biofilms, in turn, are coated in a gooey matrix...

14th Century Plague Lives On Via New Strain
2011-08-30 10:17:00

  According to a study published Tuesday, a less virulent version of the 14th century's Black Death plague is still present today. DNA testing on the skeletons of plague victims unearthed in a medieval London mass grave revealed part of the same gene sequence as the modern bubonic plague. "At least this part of the genetic information has barely changed in the past 600 years" said Johannes Krause, one of the authors of the study published in the Proceedings of the National...

Sanitizing the outside of produce may not be enough to remove harmful food pathogens, according to a Purdue University study that demonstrated that Salmonella and E. coli can live inside plant tissues. E. coli 0157:H7 was present in tissues of mung bean sprouts and Salmonella in peanut seedlings after the plants' seeds were contaminated with the pathogens prior to planting. Amanda Deering, a postdoctoral researcher in food science, said seeds could be contaminated in such a manner before or...

New research published in the Journal of Leukocyte Biology suggests that lack of expression of innate immune system receptor may play a critical role in the immune response to mycobacterial infections Are you genetically predisposed to tuberculosis? Scientists may now be able to answer this question and doctors may be able to adjust their therapeutic approach based on what they learn. That's because new research presented in the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests...

NEW YORK, June 15, 2011 /PRNewswire/ -- Bion Environmental Technologies, Inc. (OTC: BNET). Food safety concerns have been in the news again with the recent account of an outbreak of deadly E. coli in Germany, initially identified as coming from bean sprouts. In the Sunday June 12th edition of the NY Times, an article by Elizabeth Rosenthal titled "E. Coli Fallout: My Health, My Salad" directly addressed this issue. Although E. coli is generally associated with animal rather than...

Bacteria that grow in the antennae of wasps help ward off fungal threats by secreting a 'cocktail' of antibiotics explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Dr Martin Kaltenpoth describes how this is the first known example of non-human animals using a combination prophylaxis strategy similar to the one used in human medicine. This discovery could help us find novel antimicrobials for human use and lead to more effective strategies for using...
