Week 9 Discussion1. Explain the differences between antibacterial, antifungal, and antiviral drugs. Why is it important to know the difference in the drug targets? Antibacterial drugs are used to inhibit or kill bacteria. Antibacterial drugs can either be bacteriostatic or bactericidal (Parker, Schneegurt, Tu, Forster, & Lister, 2018). Bacteriostatic refers to drugs that stops the growth of bacteria but does not necessarily kill it whereas bactericidal drugs kill the bacteria (Parker, Schneegurt, Tu, Forster, & Lister, 2018). Antibacterial drugs also can be either broad-spectrum or narrow-spectrum drugs. Broad-spectrum drugs target and kill all bacteria pathogens including both gram positive and negative bacteria whereas narrow-spectrum drugs only target specific bacterial pathogens (Parker, Schneegurt, Tu, Forster, & Lister, 2018).Antifungal drugs are used as fungicides or fungistatics that disrupt the cell membrane by targeting ergosterol that is found by synthesized sterols. (Parker, Schneegurt, Tu, Forster, & Lister, 2018). Synthetic fungicides known as imidazoles drugs disrupt ergosterol biosynthesis
