For example, increased susceptibility to invasive Salmonella infections, caused largely by non-typhoidal Salmonella, as well as a few S. Typhi and S. Paratyphi cases, have been reported in individuals with immune deficiencies for interferon (IFN)-γ, interleukin (IL)-12, IL-23, and STAT1 receptors (35–38). The gene discussed is IFNG; the disease is Salmonella Infections.
