title: ELISA determination of IgM anti-LPS in the early phase of typhoid fever.
abstract: Sera from typhoid fever patients in the early stage of the disease were tested for the presence of IgM antibodies to LPS of S. typhi by an ELISA method. IgM anti-LPS were present in all 10 typhoid patients, while they were undetectable in sera from both normal and febrile controls. Determination of IgM anti-LPS can be a diagnostic aid in the early phase of typhoid fever.
