Desde 1980 que não se descobrem novos antibióticos:

E porque é que isso é importante? Porque desenvolvem resistência e porque são muito mais usados do que se pensa.
Citando:
"Antibiotics are more widely used than you might think and a world without antibiotics would be far more dangerous.
They made deadly infections such as tuberculosis treatable, but their role in healthcare is far wider than that.
Surgery that involves cutting open the body poses massive risks of infection. Courses of antibiotics before and after surgery have enabled doctors to perform operations that would have been deadly before.
Cancer treatments such as chemotherapy and radiotherapy can damage the immune system. A course of antibiotics is prescribed to provide a much-needed boost alongside your body's own defences.
Anyone with an organ transplant faces a lifetime of drugs to suppress the immune system, otherwise it attacks the transplant, so antibiotics are used to protect the body."
