Scientists solve 30-year old mystery on how resistance genes spread

2017-06-16 06:00:00| LifeSciencesWorld

[NEWS] To win the war against antibiotic resistant super bugs, scientists seek to find the origin of resistance genes. Further, they try to identify how the genes are introduced to disease-causing bacteria - so-called pathogens. Identifying where resistance genes come from and how they spread somewhat compares to finding patient zero in an outbreak, which is not an easy task. For more than 30 years, scientists have proposed that resistance genes actually originate from the microo…

Different tree species use the same genes to adapt to climate change

2016-09-22 21:05:00| Climate Ark Climate Change & Global Warming Newsfeed

PhysOrg: Recently the team discovered that two distantly related tree species use the same genes to adapt to the range of temperatures in their geographical region. Their results were published Thursday in the journal Science. Jason Holliday, an associate professor of forest resources and environmental conservation in the College of Natural Resources and Environment and a Fralin Life Science Institute affiliate, as well as Haktan Suren, a Ph.D. candidate from the same department in the Genetics, Bioinformatics...

Antibiotic Resistance Genes Increasing

2016-04-15 02:00:00| ThePigSite - Industry News

US - Around the world, antibiotic use and resistance is increasing while the discovery of new antibiotics has nearly halted. In new research conducted by Michigan State University this troubling trend is exacerbated by concentrated animal feeding operations. Results from the study show that in large swine farms where antibiotics are used continuously in feed for growth promotion and disease prevention, multidrug-resistant bacteria are likely the norm rather than the exception.
