The topic of "antibiotics" has become very popular: Non-medical journals have also been asked some questions about them, and they are a frequent topic on television and radio programmes. Some examples of common questions are: "What are bacteria and infections? What are antibiotics and what infections do they treat? When and for how long should we take them? Are they safe for humans? What is antibiotic-resistance, etc ... "
The availability of antibiotics has revolutionized the history of medicine (people talk about a pre and post-antibiotic era) saving an incalculable number of lives.


Antibiotics are drugs capable of acting selectively and specifically on bacteria by interfering with their vital mechanisms and causing an interruption in their proliferation or killing them.

They help the human immune system cope with infections by promoting healing.

Malesci pays a great deal of attention to the correct use of antibiotics and the problem of bacteria which adapt  to defeat the antibiotic taken by the patient, a phenomenon known as antibiotic resistance.

This is one of the main reasons why antibiotics should be taken only when they are really needed and only if prescribed by your physician, carefully following the prescribed methods, times and duration of treatment.
