Document Summary
Narrow spectrum: antibiotics target specific types of bacteria, such as gram negative or gram positive. Broad spectrum: antibiotics affect a wide range of bacteria them. The closer the pathogens are related to the hosts, the harder to find drugs to control. Viral infections are the most difficult to control due to living within host cells and. Antiviral drugs: target a very specific metabolic step that is unique to the specific sharing most of the metabolic pathways type of virus , therefore it usually has the narrowest spectra of antimicrobials. Prokaryotes < eukaryotes < viruses (easy difficult) Can be induced by mutagens (ionizing radiation, uv light, base analogs) Can be generated during replication of genetic material (especially in rna viruses. Transposon: a segment of dna that is capable of inserting copies of itself into other because rna polymerase lacks proofreading) Antiviral & antiretroviral therapies: most common adverse effects.
