We have a limited number of antibiotics – around 100, but all of them have a base of one of the common classes of antibiotics. When bacteria become resistant, the old antibiotic doesn’t cure a patient. So a new and stronger antibiotic is needed to save a life. The stronger drug can cause lots of damage and injuries because of the health dangers, but it will keep the patient alive.
This type of medicine is called a drug of last resort or last-line antibiotic. These are used much less often and when the situation becomes critical. If the drug of last resort doesn’t help – the patient dies of infection. The problem is that even our last-line treatment is failing with 40% of bacteria being resistant to the drug of last resort.
The bacteria which are not responding to any drug are called the Superbugs.
