Killing flu viruses with help from a frog

Frog mucus is loaded with molecules that kill bacteria and viruses, and researchers are beginning to investigate it as a potential source for new anti-microbial drugs. One of these "host defense peptides," courtesy of a colorful tennis-ball-sized frog species (Hydrophylax bahuvistara) from southern India, can destroy many strains of human flu and protect mice against flu infection, researchers report April 18 in the journal Immunity.
