Viruses exacerbate disease caused by Leishmania parasite
Washington University School of Medicine’s Stephen Beverley found that viruses hidden inside the parasite Leishmania worsen disease caused by the parasite. Now, an evolutionary survey of the viruses in related parasites suggests that Leishmania’s viruses may have helped it make the jump from infecting insects to infecting vertebrates.
Mimicking diet changes of global travel reveals clues to gut health
With the growing understanding of the importance of gut bacteria in human health, researchers at the School of Medicine studied gut motility, measuring the transit time of food moving through the gastrointestinal tract in mice in a way that mimicked the dietary effects of world travel. The study demonstrates ways to uncover how even a single ingredient, such as turmeric, can affect health through interactions of diet and gut microbes.
