A culture of Bacillus anthracis

A microbiological culture is a tool to determine the cause of infectious disease by letting the agent multiply (reproduce) in predetermined media in laboratory. A Petri dish is often used to grow bacterial cultures. More generally, the term culture is used informally to mean "selectively grow" a specific kind of microorganism in the lab. It is the foundational and basic diagnostic method of microbiology. The term culture can also, though infrequently and informally, be used as a synonym for tissue culture which involves the growth of cells or tissues explanted from a multi-cellular organism.

First, a throat smear is taken by scraping the lining of the tissue in the throat. Then the sample is blotted into an (often agar) media to screen for various harmful microorganisms.
