Antiserum to cell wall proteins of S. typhi showed immunoprecipitin lines of identity with homologous antigen, normal human serum and human transferrin. Also, anti-transferrin antibody showed immunoprecipitin band with S. typhi cell wall proteins and agglutinated S. typhi whole cells, but not Escherichia coli. It is speculated that transferrin or a transferrin-like protein present in the cell wall may play a role in iron-uptake by S. typhi.
