Broad-spectrum Antibiotics

Updated: Jan 12, 2018

Broad-spectrum Antibiotic is a type of medicine which has a relatively wide antimicrobial spectrum Explain it in an easier way is that it is a category of medicine which can resist most type of the bacteria, in this way on the other side we have got narrow-spectrum antibiotics, just like its name it is used to duel with only single one type of the bacteria. The broad-spectrum Antibiotic is normally used when we do not know what kind of bacteria is causing the problem but we still need to disinfect. However, when we classified which kind of bacteria it is, it is the time for using the narrow-spectrum antibiotic. Over used antibiotic is always not good for your health, in this case we need to use the antibiotic by following the instructions which were given out from the doctors.

In the Broad-spectrum Antibiotics, here are five normal categories: Hexapeptide, Macrolides, Polyether, Inosine, and last one the Chemical Synthetic. Hexapeptide is a kind of antibiotic mainly contain Zinc Bacitracin, Avoparcin, Thiomycin and so on. Macrolides are absorbed by the body at intestinal tract. Polyether includes Salinomycin which is frequently be used. Inosine is a type of antibiotic have anti-bacterial abilities. For the Chemical Synthetic, it contains Sulfanilamide Grous, Olaquindox and so on. These are the brief classification of the Broad-spectrum Antibiotics, in order to make us understand more about the Broad-spectrum Antibiotic, I am going to bring in an example of the Broad-spectrum Antibiotic-Penicillin.

''It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria are the Gram-negative bacilli, and the most susceptible are the pyogenic cocci ... In addition to its possible use in the treatment of bacterial infections penicillin is certainly useful... for its power of inhibiting unwanted microbes in bacterial cultures so that penicillin insensitive bacteria can readily be isolated.'' -Alexander Fleming-
