Today resistance to antibiotics is developing at such a pace that we can face the problem of lack of medicines for infections in the near future.
So why antibiotics do not work?
Why antibiotics do not work?
Antibiotics are designed to kill orblocking the growth of bacteria, but not all are equally sensitive bacteria. Some are naturally susceptible to the drug. Resistance emerges spontaneously as a result of random mutations. Resistant strains can continue to multiply and thrive, from one bacterium to get a million new. Antibiotics are well sensitive to bacteria while any resistant not killed by the action of drugs. The resistance may also be transferred from one bacterial species to another.
Whether to blame the excessive use of antibiotics?
The more antibiotics are used, the longerchance that bacteria will develop immunity to it. Very often, antibiotics are used inappropriately. Many of them are appointed by and are used for mild infections when they can not register at all. Antibiotics are of no use to treat infections caused by viruses, for example, such as the common cold or flu.
Another problem - people who often are not the entire course of antibiotic therapy. Early discontinuation of treatment means that most of the surviving bacteria become resistant to the drug.
It is also believed that the widespread use ofantibiotics for the treatment and prevention of diseases has led to the emergence of resistant strains in animal husbandry, some of which are transmitted to humans through food. Also resistant bacteria are spread through direct contact with a person or animal.
Recently, cases have been reportedvenereal diseases (gonorrhea), which was resistant to all the antibiotics commonly used to treat this infection. Also recorded cases of multidrug-resistant TB and the emergence of new threats to the treatment of drug-resistant bacteria, such as New Delhi metallo-beta-lactamase (NDM-1).
International travel and the travel of infected people also contribute further to the rapid spread of resistant bacteria to other countries.
Why do we lack of new antibiotics?
Pharmaceutical companies pay greaterattention to the search for new antibiotics, as well as the development of new vaccines for preventing common infections. But these projects are expensive, both in terms of economic efficiency, they may be less attractive for companies than other business opportunities. Many of the "new" antibiotics - chemical variants of older medicines, which means that the development of bacterial resistance may occur very quickly.
What do we have to do?
If the doctor has prescribed antibiotics, be surethat you have gone through the full course of treatment even if you feel better much sooner, because the course is pending stimulates the emergence of bacterial resistance.
Remember that antibiotics - are important medicines and should be taken only on prescription.
Antibiotics have no effect on viral infections, bacterial only.
Do not share your antibiotics with someone else.
The elementary rules of hygiene - hand washing and cleanliness when preparing food - can stop the spread of many bacteria, including some resistant harmful microorganisms.
