Effects on organisms
Sulfonamides are generally effective against most gram-positive and many gram-negative organisms. Specifically enteric bacteria and other eubacteria are affected by the antibiotic as it kills the bacteria by restricting the production of folic acid, which is essential for their growth. However strains of bacteria can be resistant to the antibiotic. If a bacterium is resistant to a sulfonamide, it is resistant to all the forms. Furthermore, sulfacetamide is toxic to soil organisms. Synthesis
Sulfacetamide is synthesized either by direct alkylation of acetamide with 4-aminobenzenesulfonyl chloride, or by reacting  4-aminobenzenesulfonamide with acetic anhydride and subsequent selective, reductive deacylation of the resultant acetamide using a system of zinc-sodium hydroxide. == References ==
This can affect both genders and includes a variety of manifestations of varying severity. Type 3: Autoimmune manifestations primarily limited to the GI tract. This can affect both genders and may also be considered IPEX-like. There is considerable overlap in these disorders, and it is often unclear how to properly distinguish between them as the responsible genes are generally poorly understood at this time. Treatment
Medical therapy is commonly used, most typically with corticosteroids (budesonide and prednisone). However, some patients are refractory to corticosteroids, and in these patients immunosuppressive therapy with azathioprine, cyclophosphamide, tacrolimus, cyclosporine and infliximab has been described. An intravenous nutrition such as total parenteral nutrition and/or a special diet may be necessary. Hematopoietic stem cell transplantation may be curative. References
