| Abstract:
|
A simple, rapid and early diagnostic test for typhoid fever urgently needed for clinicians. It’s have been discovered 36
kDa OMP’s from Makassar, South Sulawesi, Indonesia. This study was aimed to determine potency of 36 KDa OMP’s
to react with antibody of typhoid fever patients as candidate immunodiagnostic of typhoid fever. An OMP ‘s of S.
Typhi with an apparent molecular mass of 36 kDa that is highly immunogenic, evokes humoral and cell-mediated
immune responses, and confers 100% protection to immunized rats against challenge with very high doses of S. Typhi
has been identified. Further, very efficient clearance of bacteria from the liver of immunized animals was seen. This
protein is recognized by the antibodies present in serum of typhoid patients. The agglutination slide indicated that the
immunoreactive protein evoked a strong immune response in rats. Serology test by dri-dot resulted OMP can react
with serum of typhoid patients (n=25) with sensitivity 100%
