Mice orally infected with a bacteria responsible for most stomach viruses that were put on a fast for 48 hours before exposure had fewer signs of bacterial infection compared with those that were fed, the researchers said. The mice in the study were infected with Salmonella enterica serovar Typhimurium, which causes gastroenteritis, an infection humans experience as abdominal cramps, diarrhea and vomiting, researchers said. However, when fasted mice were infected with Salmonella intravenously, they did not have similar protection...
