Antibiotic Sensitivity And Resistance

In 1928 Alexander Fleming had opened special capacity of fungus called Penicilinum. That tool was able to kill all Staphylococcus colonies in its surrounding. So started the 50 years long period of successful fight against bacteria. In 1935 was found the firs sulfanilamide. Due to this medication were saved a lot of lives in the First and Second world wars. At that time almost all infection agents were sensitive to antibacterial drugs.

Time passed and pharmaceutical companies released more and more drugs. People began to use them not only for treatment. Antibacterial gone for water purification, extension of food storage period and even for every-day beauty items. So antimicrobial drugs transformed person ability to be cured. And now we cannot treat many infectious diseases that were killers only a few decades ago.

Up-to-date scene is that more and more antibiotics became powerless in front of bacteria. Doctors use several terms in relation to the antibiotic efficiency: sensitivity and resistance. So sensitivity is special capacity of medicine to kill spectrum of infection agents. If the tool has wide antibacterial activity that means a large group of agents are sensitive to this tool. That’s good for patients suffering from infections. Resistance means capacity of bacteria to be not injured and liquidated with antibiotic.

For example, in the U.S. there were registered presently more than 100 antimicrobial agents. Most of them are able to do away with infections. There are two variants how it works:

• by destroying of cells` paries of microorganisms and of its organelles;

• by decreasing the ability of these bacteria to reproduce the similar to themselves.

In all the ways antibiotic have to stop dissemination of infection. That should be in the ideal way. But now deals with this medicine are those:

• sensitive of microorganisms to antibiotics tends to fall;

• amount persons who have resistance to one or other antibiotic increases.

In conclusion doctors have situation when antibacterial medications cannot deal with their main role – to kill the bacteria. So doctors fit to pick up necessary antibiotic to which inflectional agent sensitive is. So humanity have to use them only if these drugs are needed.
