Antibiotiques

According to the World Health Organization, some antibiotics currently available may no longer be effective next 10 to 20 years. Given our favorite medications, bacteria have learned to defend itself and we are not sure of winning the battle. Are we on the eve of a return of large epidemics? How to fight against the drug? A dossier to understand ...

 
The bacteria are the resistance
After revolutionizing the treatment of infectious diseases, antibiotics now appear to have stalled. In the world of the infinitely small, the bacteria do confess never defeated. Thus, the phenomenon of resistance of the latter is becoming more widespread.

Antibiotics

Often antibiotics are compounds derived substances isolated in nature. Penicillin, for example, was accidentally discovered by Sir A. Fleming in 1928 when he tried to understand why the bacteria that grew in his lab were dead. He finally realizes that kind of mold manufacturing Penicillinum naturally penicillin was introduced into its culture dishes!

Courses of action varied
Today, there are a large number of antibiotics whose mode of action are different. Some act on the wall or membrane of the bacteria causing their destruction. Others will act in the machinery of bacteria to block their development and survival. Finally, certain antibiotics act directly at their DNA to prevent their division and proliferation.

Antibiotics, particularly penicillin and cephalosporins may cause severe allergic reactions or even death. He must always tell your doctor or pharmacist if you know to be allergic to certain antibiotics.

Effects on intestinal flora
Absorbed oral antibiotics in prolonged treatment can cause gastrointestinal side effects such as diarrhea. Our gut contains a large number of nonpathogenic bacteria (which do not cause disease) and beneficial to our digestion. These bacteria are our intestinal flora. They will facilitate the degradation of our food, making possible their assimilation by the body. Taking prolonged antibiotic can kill a certain number of these bacteria and thus disrupt our digestion.

While respecting prescription
During antibiotic treatment compartment, it should stay within the limitation of their doctor and in particular the dose and duration of treatment. In fact, stop the treatment when you feel better and before such treatment is finished may encourage the emergence of bacteria resistant to the action of the antibiotic and cause a relapse. This resistance makes the new treatment more difficult.

All infections are not treatable with antibiotics. The use of an antibiotic (and any medicine in general) makes sense only if it is effective on the disease that we want to heal. Viral infections in particular are not sensitive to antibiotics and most other nasopharyngitis and colds are viral! In some cases, prescription antibiotics can still be of interest to prevent a bacteria infecting the subject comes already weakened.

Similarly, oral administration of an antibiotic on its own is banned because only a doctor is fit to know the antibiotic that corresponds to your infection. Taking an inappropriate antibiotic may aggravate the infection, so always consult your physician.
