Abstract
Salmonella enterica serovar typhi (S.typhi) is one of the most important gram negative bacteria that cause enteric fever and stimulate the immune response in infected patients. This study aimed to compare the humoral and cellular immune responses in patients infected with S.typhi. For this, the concentration of three immunological markers viz., Macrophage migration inhibitory factor (MIF), Cluster of Differentiation 19 (CD19), and Interleukin 23 (IL-23) were measured by the Enzyme-Linked Immunosorbent Assay in the serum of 54 S.typhi infected patients, and 31 healthy individuals. The results demonstrated a significant increase (P =<0.05) in the serum concentration of MIF in patients infected with acute infection of S. typhi compared with healthy individuals but there were no significant differences in chronic infection. While there was a significant increase (P =<0.05) in serum concentration of CD19 and IL-23 in patients infected with acute and chronic infection of S.typhi as compared with healthy individuals. In conclusion, macrophage migration inhibitory factor plays a vital role in patients infected with acute infection of S. typhi and has no synergism with T-cell and B-cell in acute and chronic infection.
