Question

Quizplus · Accepted Answer

The selection of culture media should be based on the type of specimen and the expected infectious agents. It is important to use media that will support the growth of the suspected organisms and also distinguish them from other organisms that may be present. Nonselective and differential media can be used, but they should be chosen based on the specific needs of the specimen and the suspected organisms. Using only broth for the initial inoculation may not provide enough information about the nature of the infection, and it may delay identification of the causative organism.
