Today, around the world people are very concerned about the continuous increase in the phenomenon of oily drugs for many types of bacteria. Many antibiotics that have been considered as saviors of the past are illnesses, now proved to be no longer effective for treatment. The antibiotic treasure is becoming more and more limited and scarce. Antibiotic resistance has begun .

What are antibiotics?

Antibiotics are natural substances cultured from microorganisms, either synthesized or semi-chemically synthesized. They are capable of destroying or slowing the growth and expansion of pathogenic microorganisms. These can be antibiotics (antibiotique), sulfa (sulfamide), antiviraux, fungicides (antifongiques), disinfectants (desinfectants) and antiseptics (antiseptiques).

What is the phenomenon of antibiotic resistance?

Antibiotic resistance or antibiotic resistance occurs when a type of microorganism evolves to become more resistant or completely resistant to antibiotics that previously could be treated.

Why can greasy phenomenon occur?

There are many causes such as indiscriminate use of antibiotics, improper use of drugs, disrespect of the dose and duration of treatment, as well as the refusal to take as much medicine as the doctor has prescribed. .

In addition, the abuse of antibiotics in animal husbandry, agriculture and fisheries also contributed significantly to the formation of antibiotic resistance in humans.

Finally, the problem of using disinfectants (nettoyant antibactérien) to clean too often and improperly can also help to produce strains of resistant bacteria.

How does resistance develop?

Bacteria receive resistance from many ways. From other bacteria that carry this property, or due to natural mutation . Is this a natural phenomenon to protect an organism's survival? Resistance is attached to the bacterial genome, or it may also be in chromosome dependent units, called plasmides . These are extremely small and mobile DNA rings. When bacteria die, these plasmides will be released into the environment and thereby infect other bacteria. As for viruses, when reproduced (called replication), they need to enter the bacteria to extract plasmides and transfer them to other bacteria.

There are many causes of antibiotic-resistant bacteria.

Why are bacteria resistant to drugs?

Drug resistance may occur under one of the following mechanisms:

  • Changing the drug's target of action on bacteria. For example, altering proteins on bacteria that Penicilline will bind to.
  • Disable drugs with beta lactamase enzyme.
  • Reducing the permeability of bacterial cell membranes, the drug does not work.
