And not only did it kill Staphylococcus, it also worked when he tried it against other bacteria, including Streptococcus, Meningococcus and Diphtheria bacillus. Antibiotics work against bacterial infections; many of us have used them to treat infections ranging from strep throat to bladder infections and many types of skin infections.


Antibiotics work by affecting things that bacterial cells have but human cells don’t. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. Bacteria and human cells also differ in the structure of their cell membranes and the ...


Antibiotic resistance is another problem that has led to the need for different types of antibacterial drugs. Once a certain antibiotic becomes widely used, bacteria quickly develop resistance to being harmed by it, so new antibiotics have to be found to kill these tougher bacteria.


The majority are made by denizens of the dirt, but both fungi and bacteria get into the act. But what do antibiotics do? How do they fulfill their role as agents of warfare? They do kill bacteria - but how? In a bacterial population, do all members get killed? Unfortunately, no, many antibiotics work by preventing bacterial growth.

But, actually how do antibiotics kill bacteria? Varied types of antibiotics work differently and kill selective bacterial strains, which we will discuss in this article.

Antibiotics are either bactericidal (they kill the bacteria) or bacteriostatic (they keep the ...


Introduction of DNA breaks and replication fork arrest. The ability of quinolone antibiotics to kill bacteria is a function of the stable interaction complex formed between drug-bound topoisomerase enzyme and cleaved DNA 4.Mechanistically, based on studies employing DNA cleavage mutants of gyrase 23 and topoIV 24 that do not prevent quinolone binding, as well as studies that have shown that ...
