title: Ontogeny of the ferret humoral immune response.
abstract: Infant ferrets are born with nearly undetectable immunoglobulin levels, but by 9 days of age the infant ferret serum contains 77, 29, and 13% of adult mean serum levels of IgG, IgA, and IgM. Transmucosal uptake of IgG by the infant ferret occurred for the first 30 days of life. The specific anti-respiratory syncytial virus neutralizing titer of whole milk was 5.5 times higher than maternal serum despite a lower concentration of immunoglobulins in the milk.
