The answer was a resounding no. https://medicalxpress.com/news/2019-11-salad-bars-easy-bioterroristsand-america.html Thu, 07 Nov 2019 09:30:01 EST news492341076 The emergence of new pathogens like West Nile Virus, Ebola, Dengue, and Zika, threaten human health on a global scale. Identification of these pathogens requires a rapid response from industry to develop new tests and the FDA to assess test safety and efficacy. A report in The Journal of Molecular Diagnostics evaluates the new OpenArray system that offers simultaneous detection of multiple viruses, bacteria, and protozoan pathogens in human blood samples. Investigators determined that this system is a promising tool for flexible, fast, and accurate blood screening. https://medicalxpress.com/news/2017-06-technology-enables-effective-simultaneous-multiple.html Tue, 13 Jun 2017 02:20:01 EDT news416537092 For the second time, a clinical isolate of a bacterial pathogen has been detected in humans in the United States which carries the colistin resistance gene, mcr-1. This may also be the first case to show up in the US. That would be concerning because plasmids, genetic elements that are independent of the host genome, often jump between different bacterial species, spreading any resistance genes they carry. The research, the most comprehensive and contemporary surveillance data for mcr-1 to date, is published July 11 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology. https://medicalxpress.com/news/2016-07-colistin-resistant-gene.html Mon, 11 Jul 2016 13:00:04 EDT news387457069 The National Institutes of Health said it has uncovered a nearly century-old container of ricin and a handful of other forgotten samples of dangerous pathogens as it combs its laboratories for improperly stored hazardous materials. https://medicalxpress.com/news/2014-09-nih-ricin-forgotten-germs-labs.html Sat, 06 Sep 2014 01:40:02 EDT news329185430 With the evolving changes in the delivery of healthcare to children worldwide, which frequently include long-distance travel and lodging for specialized medical treatments, the Society for Healthcare Epidemiology of America (SHEA) partnered with Ronald McDonald House Charities to release the first-ever infection prevention and control guidelines for "home away from home" pediatric residential facilities to help prevent the spread of infectious pathogens among vulnerable pediatric populations.
