Not always prescribed wisely, these molecules used massively since the 1970s could become less and less effective in the fight against bacteria such as staphylococci, pneumococci, or salmonella.
Bacteria have learned to defend themselves against antibiotics
Bacteria protect themselves either by changing their outer shell, making them impermeable to the antibiotic, or by changing their inner system, allowing them to tolerate antibiotics or eliminate them before they have a chance to. ‘to act.
But the arsenal available to doctors is still sufficient to deal with the most serious eventualities. It is only in a hospital environment that certain totally resistant bacterial strains can be found.
The French consume too many antibiotics
The vast majority of these infections are of viral origin and do not automatically require antibiotics, which only act on infections of bacterial origin.
The common cold, for example, is caused by a virus, not a bacteria. In this case, the prescription of antibiotics is supposed to prevent secondary bacterial infections that actually occur after a viral infection.
It is not always easy to differentiate viral infections from bacterial infections. But with regard to tonsillitis, for example, there is a test to know in a few minutes whether the angina is of viral or bacterial origin.
Excessive antibiotic intake does not cause allergies
There is no relationship between the amount of antibiotics absorbed and the declaration of an allergy. An allergy to an antibiotic may appear quickly, late, or never. Almost all of the patients do not develop an allergy.
Are new antibiotics still discovered?
Scientists are discovering fewer new classes of antibiotics because they are looking for less. In recent years, researchers have had other priorities, particularly in the area of viruses.
The future will undoubtedly be the vaccine. Especially for ear infections. There are already vaccines that make it possible to develop antibodies against bacteria that are present in the nasopharynx of children. If these vaccines keep their promises, we should soon see a decrease in resistant pneumococcal ear infections.
Bacteria and viruses
Bacteria are living beings composed of a cell with a diffuse nucleus and reproducing by division. Each bacterial division gives rise to two bacteria.
Viruses are living beings that are parasitic on cells, reproducing inside its host from its genetic material alone.
