They live inside us. For ages, humans have fought against bacteria and many often, humans have died. Successfully one hundred years ago Alexander Fleming discovered penicillium as a great medicine to fight and win against infections. For instance, along the Secession War or the IWW, many surgeons worked cutting arms and legs. The other problem was how protect soldiers from dysentery or rates infections. Nobody knew anything about bacteria troubles. The Fleming discover was a new opportunity to survive to millions of people around the World. Today it continues being a good way to protect us. But not everything are good news. Last decades ago, many pharmacy companies are testing new medicines. Of course, occidental people want the best product and they use to buy new medicines to protect themselves. Many often they forget to finish their treatments and give an opportunity to survive and muting their illness. On the other hand, people try to save money and practice medical tourism. Look for a hospital in a cheaper country and go there to cosmetic surgery. They want to follow being young, but when they come back home, they can bring new infections which need hard and expensive treatments. And last but not least important is the use of medical treatment to protect animals from illness. Cows and sheep eat paracetamol or ibuprofen as a normal diet to protect them from diseases. Of course, when we eat them, we introduce some treatment which could be dangerous for us. I don’t try to find any solution but the war against bacteria will be hard and nobody knows who will be the winner. Last week the Australian government decided to add a new virus to kill millions of rabbits in Australia. They want to preserve their fields from a foreign specie. Good luck.
