How do antibiotic-rich environments like hospitals speed up the rate at which superbugs increase their percentage of the bacteria population?

Superbugs is the name used to illustrate the bacterial strains, which are resistant to the majority of the general antibiotics used at present. The antibiotic resistance is a naturally taking place procedure, which can be prevented for some time, however, cannot be ceased down.  

With time the bacteria develop the tendency to get amend with the drugs, which are developed to eradicate them and get modify to make sure their existence. These superbugs develop a resistance to antibiotics more briskly in comparison to other bacteria and are most usually found in hospitals.  

In the environments of hospitals, the superbugs accelerate their percentage of the bacterial population by elevating the selective pressures leaving majorly the resistant bacteria alive.
