Opis

A large number of antibiotics are available. They are classified by their chemical structure since drugs with similar chemical structures tend to have similar actions. Based on clinical experience, physicians may know that some types of infection normally respond to specific antibiotics, but if the infection fails to respond, or recurs, it may be necessary to do culture and sensitivity testing. Microorganisms develop resistance to antibiotics, and so there is no assurance that an antibiotic will retain its effectiveness against some types of infection.

Patterns of bacterial resistance also depend on the environment where the infection is acquired. In hospitals, where antibiotics are widely used, microorganisms are usually more resistant than those found outside the hospital. Infections developed by hospitalized patients often require different treatment from infections developed outside the hospital (community acquired).
