It’s critical to know which antibiotics will be effective against the particular pathogen (i.e., disease-causing agent) causing the problem. This means that (1) identify the species (and strain) of bacteria (or other pathogen) must be identified and (2) the drugs most effective at inhibiting their growth must be determined. The only reliable way this can be done is a culture and sensitivity test that is actually growing bacterial by cultures and exposing them to various types of antibiotics to see which drugs kill or inhibit the bacterial growth.
How is a Culture and Sensitivity Test Done?
A sample of infected tissue or discharge from the infected area is sent in a special culture tube to laboratory for testing.
