Developing a Salmonella vaccine in space

Source of Article:

4/24/2009-According to Discovery News, researchers are working with NASA to develop a Salmonella vaccine. The studies, taking place aboard the International Space Station, began because NASA was concerned its astronauts might be more susceptible to food poisoning in space due to their weakened immune systems. The researchers discovered that microgravity changes the genetic makeup of Salmonella, providing insight into a new way to possible control the bacteria on Earth. Cheryl Nickerson, a researcher from Arizona State. Univ., noted that the genetic changes in space-borne Salmonella made the bacteria more virulent than identical samples on Earth. Because the environment inside the intestines is similar to weightlessness, Nickerson is hopeful her research will to a vaccine and other treatments for food poisoning.
