Raccoons with bird flu antibodies found
Japanese researchers say they've found 10 raccoons that show signs of having fought off previous bird flu infections.
The discovery marks the first time anyone in Japan has seen mammals with bird flu virus antibodies, The Yomiuri Shimbun reported Wednesday. Researchers said the raccoons likely infected with the H5N1 virus by eating the carcasses of infected birds or through antibodies passed on by their parents.
