title: Postnatal changes of IgG and IgM levels in squirrel monkeys (Saimiri sciureus).
abstract: Serum IgG and IgM levels were measured in domestically bred squirrel monkeys (Saimiri sciureus) ranging in age from 0 days to 42 months, as well as in adult squirrel monkeys from the wild estimated to be 60 months or older. The results indicated that the transplacental transfer of IgG occurs in the squirrel monkey but the transferability is lower in the squirrel monkey than in the cynomolgus monkey. Immune response in the squirrel monkey occurs just after birth, as shown by IgM production.
