title: [Persistence of transplacental antibodies against rotavirus in children less than 6 months of age].
abstract: The persistence of antibodies against rotavirus was studied in the sera of 54 recently born infants up to six months of age; likewise, in the sera of their mothers. Serum positivities were found to be similar in both, showing 96% for those with antibodies and 94.4% for the latter. The percentage of infants with antibodies dropped gradually to the 4th month of age and since then rises in the titre of antibodies began to appear in four infants, which indicated there had been rotavirus infections. These studies lead to believe that in spite of the presence of serum antibodies, rotavirus multiply in the enteric tract and do not bring about serum antibodies, but perhaps, they stimulate the production of coproantibodies, which do not allow in the future the implantation of these viruses in the intestine.
