Antibiogram is a laboratory test intended to guide the choice of adequate antibiotic to treat a given bacterial infection. In the antibiogram cultures of bacteria obtained from tissues contaminated by the infection under study are submitted to the action of different antibiotics. After some time it is verified which of the antibiotics were successful in interrupting the bacterial growth or in killing the bacterial population.
The antibiogram is very important to avoid exaggerated and inefficient use of antibiotics and the emergence of multiresistant bacteria.
