Different ones work in different ways. One common method is interference with cell wall synthesis. Another is interference in nucleic acid replication. You just have to plug through them individually.

No. That is, some medicines "kill" in ways we don't understand. Oh OK, most we do understand. To generalize, they kill by messing up the way "microbes" "eat" or reproduce. Some do one, some the other, some both. The "exact" way they do it depends on the microbe and especially on the medicine. You question is like asking how poisons kill. There are many many ways. ALL medicines are poisons. The old saying "its the dose that makes the poison" is true. Anyway to give a completely unenlightening answer: medicines interfere with the metabolism of a cell or the reproductive pathways of a bacteria or virus. To give you the details would require you to understand the metabolism or reproductive pathways of these "microbes". A task far to lenghty to happen here. You would be better off researching specific drugs like penicillin or an HIV cocktail.

Antibiotics may disrupt cell wall precursor leading to lysis thus killing the microbes. Removing the key component of bacteria called RNA polymerase is another bactericidal action done by antibiotics.

the medicine creates cells that protect the immune sistem once these cell grow they start eating the microbes until they dissapear,,,,the medicine also kill good cells but very few ones theses cell are alive while you take the medicine
one you stop taking it the cells die and your body takes them out
science has
developed a new class of vaccines, based on killed but metabolically active bacteria, that simultaneously takes advantage of the potency of live vaccines and the safety of killed vaccines. the new vaccine remove genes required for nucleotide excision repair rendering microbial-based vaccines exquisitely sensitive to photochemical inactivation with psoralen and long-wavelength ultraviolet light. Colony formation of the nucleotide excision repair mutants was blocked by infrequent, randomly distributed psoralen crosslinks, but the bacterial population was able to express its genes, synthesize and secrete proteins.

Primarily By Antibiotics, Several Mechanisms, I Personally Think it is Time to Implement Phages.

it messes w/their dna and/or cell wall....by either,they can no longer multiply and/or survive...good luck......
