ABSTRACT
Hybrid clones producing monoclonal antibodies (MAbs) specific for Salmonella paratyphi A (72 clones), S. paratyphi B (9 clones) and S. paratyphi C (8 clones) were produced by using the affinity purified Salmonella protein (Bp) as immunogens. MAbs to S. paratyphi A and S. paratyphi B reacted specifically with the 52 kDa homologous flagellin protein components while those to S. paratyphi C reacted with a 61 kDa flagellin protein component. The MAbs against S. paratyphi A and S. paratyphi B were used to establish a double antibody sandwich ELISA for detection of the 52 kDa flagellin antigens in serum samples from patients with acute paratyphoid A and paratyphoid B fever. With this assay system, 6.25 ng per ml of flagellin antigens of S. paratyphi A and S. paratyphi B could be detected. However, the assay system could not detect the flagellin antigens in patients' sera. The presence of IgM antibodies to the 52 kDa antigens of S. paratyphi A and S. paratyphi B in the acute sera from paratyphoid A or paratyphoid B patients suggested that the 52 kDa protein components of both salmonellae are good immunogens for human and might be used as antigens for early diagnosis of paratyphoid A and paratyphoid B fever.
