Rong with an epidemic. Antibiotics against superbacteria

We all know the history of the discovery of antibiotics. Alexander Fleming accidentally infected the culture of staphylococci with mold mushrooms. Thus began the era of antibiotics, saving millions of human lives.
But today a new threat has faced humanity. When we use an antibiotic, 99.9 % of bacteria die, and 0.1 % survives and becomes resistant to it. In addition, antibiotics are used uncontrollably for diseases that are not treated with them. So there are superbacteria that is very difficult to win. Is humanity a new epidemic awaits? Scientists from around the world are trying to find new medicines. Matt McCarthy, a doctor and a scientist, studies the properties of a new antibiotic that will help stop it.
In the book we are waiting for meetings with patients whose life hangs in the balance. Can Dr. McCarthy save his patients who are powerless to help modern medicine?
