Why develop resistance to antibiotics?</a>

Today, resistance to antibiotics is developing at a pace that we can face in the near future the problem of the lack of drugs for infections.

So why do antibiotics stop working?

Why do antibiotics stop working?

Antibiotics are designed to kill orBlocking the growth of bacteria, but not all bacteria are equally sensitive. Some of them, naturally, are immune to the drug. Resistance also arises spontaneously as a result of random mutations. Stable strains can continue to multiply and thrive, and from one bacterium will get a million new. Antibiotics work well on sensitive bacteria, while any resistant do not die from the action of drugs. Resistance can also be transmitted from one species of bacteria to another.

Is this excessive use of antibiotics?

The more antibiotics used, the moreChances that bacteria will develop immunity to it. Very often antibiotics are used not for their intended purpose. Many of them are prescribed and used for mild forms of infection, when they can not be prescribed at all. Antibiotics are useless for the treatment of infections caused by viruses, for example, such as a common cold or flu.

Another problem is people who often do not complete the entire course of antibiotic therapy. Early cessation of treatment means that most of the surviving bacteria become resistant to the drug.

It is also believed that widespread useAntibiotics for the treatment and prevention of diseases in livestock led to the emergence of resistant strains, some of which are transmitted to humans through food. Also, resistant bacteria spread through direct contact with a human or animal.

Recently, cases have been reportedA venereal disease (gonorrhea) that was resistant to all antibiotics commonly used to treat this infection. There have also been cases of multiple drug resistance to the treatment of tuberculosis and the emergence of threatening new resistant bacteria, such as New Delhi metal-beta-lactamase (NDM-1).

International travel and travel of infected people also contribute to the further rapid spread of resistant bacteria to other countries.

Why do we lack new antibiotics?

Pharmaceutical companies are giving increasedAttention to the search for new antibiotics, as well as the development of new vaccines for the prevention of common infections. But these projects are expensive, and from the point of view of the economic efficiency for companies they may be less attractive than other business opportunities. Many of the "new" antibiotics are chemical versions of old medicines, and this means that the development of bacterial resistance can occur very quickly.

What do we have to do?

If the doctor prescribed antibiotics to you,That you have completed the full course of treatment, even if you feel better much earlier, because the non-completion of the course stimulates the appearance of resistance of bacteria.

Remember that antibiotics are important medicines and should be taken only according to the doctor's prescription.

Antibiotics do not act on viral infections, only on bacterial infections.

Do not share your antibiotics with someone else.

Elementary rules of hygiene - washing hands and keeping clean while preparing food - can stop the spread of many bacteria, including some resistant harmful microorganisms.
