Dictionary » A » Antibiotic AntibioticAntibiotic (Science: pharmacology) a chemical substance produced by a microorganism which has the capacity, in dilute solutions, to inhibit the growth of or to kill other microorganisms. antibiotics that are sufficiently nontoxic to the host are used as chemotherapeutic agents in the treatment of infectious diseases of man, animals and plants. Origin: gr. Bios = life Of or relating to antibiotic drugs.A chemical substance derivable from a mold or bacterium that kills microorganisms and cures infections; when antibiotics were first discovered they were called wonder drugs.Antibiotics are used in medicine due to their capability of inhibiting or neutralising alien agents that enter the human body. Antibiotics are naturally produced by organisms as a means of defense and hence survival. Through natural selection, organisms that fall prey to antibiotics begin to develop a resistance, and the effects of the antibiotics diminish over time until the organisms are immune to its effect.

I am guessing the effectiveness of the antibiotic would then depend on whether the antibiotic can get inside the cultured cells. If it can and the bacterial cells are sensitive to it, then i guess ...

Antibiotic effectYes and no. Many antibiotics do as you say, that is they only suppress the bacterial growth but do not kill the microbes. These antibiotics are called bacteriostatic. Streptomycin, however, is bactericidal antibiotic as far as I know, ...

Antibiotic effectHello, Is it true that antibiotics such as streptomycin can only suppress the growth of bacteria in a cell culture dish and if there were already bacteria in the dish, once you stop adding the antibiotic, they will start to grow? Are ...
