The discovery of a new regulatory component in an infectious bacterium could aid efforts to explain its ability to survive in the human body, report microbiologists at the University of Texas Health Science Center at Houston (UTHealth) and University of Maryland, College Park, in the journal Science.
With the largest Ebola outbreak in history raging through West Africa, understanding whether the virus is changing as it spreads through different populations can help responders know what treatments to use and also help research laboratories develop new tools to speed diagnosis in the field.
The MERS coronavirus has caused disease outbreaks across the Arabian Peninsula and spread to Europe several times. The severe pneumonia virus has claimed the lives of several hundred people since its discovery in 2012. For a long time, scientists have been puzzled over how easily the pathogen spreads from human to human. An international team of researchers led by virologists from the University of Bonn have now come to the conclusion, through direct observation, that the rate of human transmission is low. Still, a third of infected persons with symptoms die. The results are now being presented in the renowned New England Journal of Medicine.
