7. Sulfonamides are used to treat bacterial infections. Why these medicines do possess antibacterial effect, but do not manifest the cytostatic effect on human body cells? For the answer: d) specify processes which are disturbed in bacterial cells in sulfonamides administration; e) explain the inefficiency of sulfonamides in medium with high content of p-aminobenzoic acid (PABA) (pus, tissue degradation products).
