The space presented by Gloria Serra revolves around bacteria and shows where they hide and how they are capable of multiplying in record time. Every day we are in contact with billions of bacteria. They are in the air, in food, in water, in our own body… we are surrounded by them. With a kiss on the mouth we share 80 million bacteria. A smartphone screen can contain 600 types of these microorganisms, while a clean toilet contains more than 20. The program travels to a town in Ciudad Real where more than 200 residents fall ill due to bacteria. ‘Research team’ also discovers that there is a place where bacteria are becoming invincible: hospitals, a true focus of infections. Every year 250,000 people are infected, especially patients who go through operating rooms. From being the most sterile places they have become the most dangerous. Only antibiotics can kill bacteria. But they are wearing off. The fault according to scientists could be that we are overmedicated and not only us, but also the animals. More antibiotics are given to healthy animals than to sick humans. The UN has warned of the situation. Either we begin to take action or by 2050 bacterial infections may kill more people than cancer or cardiovascular disease.
