The immunogenicity of milk from various species for the guinea-pig.

Young guinea-pigs, sensitized and challenged by the parenteral administration of bovine and human milks, died of anaphylaxis while others, sensitized and challenged with guinea-pig milk, were unaffected. The type of milk fed to young guinea-pigs from birth did not alter the basic immunogenicity of cow's milk or the lack of immunogenicity of guinea-pig milk for the young guinea-pig.
