Bacteria contribute to immune suppression in skin after repeated schistosome exposure

Our two square meters of skin act as a defensive barrier against environmental pathogens but is also covered by beneficial commensal bacteria. We live alongside these bacteria without excessive and unnecessary immune responses, which could destroy the skin's function as a barrier and so make us ... Read More

U.S. report shows mixed progress on curbing foodborne pathogens

U.S. cases of two deadly types of foodborne pathogens have fallen sharply since 2008, but rates of other key types of foodborne bugs have increased, according to the latest report on nine pathogens tracked by health officials.

"The picture is mixed," said Dr. Patricia Griffin of the U.S. Cent... Read More
