Comparison of Bactericidal Activity of Serum Collected from Typhoid Patients and Normal Human Against Salmonella typhi at Various Incubation Time

Susceptibility to the serum bactericidal system is a widespread characteristic of gram-negative bacteria. In addition to the many well-documented instances of enterobacterial susceptibility to complement, serum is known to possess bactericidal and bacteriolytic activity against susceptible representatives of practically every gram-negative genus so far examined. The bactericidal effect of normal human serum plays an important role in host defense against bacterial infection. This phenomenon has been widely noted and studied since the late 1800s and has been shown to be complement mediated. Early colonization of the intestinal tract
