There is no single antibiotic that can defeat all bacteria; there are over 15 categories of antibiotics available, differing in their chemical structure and bactericidal action.
The action of antibiotics is therefore very important, but in order for them to continue to be effective, they must be used appropriately.
In the long term, improper and excessive use can lead to antibiotic resistance.
What is antibiotic resistance?
A bacterium is defined as “resistant to antibiotics” when it is able to resist the attack of specific antibiotics supposed to fight it.
Some bacteria are normally resistant to certain antibiotics (intrinsic resistance); in other cases, resistance occurs as a result of genetic changes, which make bacteria that were previously susceptible to antibiotics resistant (acquired resistance).
This type of resistance is a natural phenomenon.
However, it should be emphasized that excessive or inappropriate use of antibiotics can significantly contribute to the emergence and spread of resistant bacteria, as they continue to multiply.
Bacteria resistance is a major health problem around the world.
Treating infections caused by resistant bacteria is very difficult because it is necessary to regain the effectiveness of the antibiotic.
This can delay the identification of the most appropriate treatment and can also lead to major complications for the health of the patient.
Correct use of antibiotics
Antibiotic therapy must be prescribed by the doctor and the patient must scrupulously respect the schedules and doses of administration: compliance with these indications allows drugs to fight effectively against bacteria.
It is often thought that the flu should be treated with antibiotics, but in fact in most cases the flu has a viral origin, so they are not effective and should not be taken.
