One of the most important reasons being its utility in diagnosing infectiousdiseases. Isolating an organism from sites in body normally known to besterile is an indication of its role in the disease process. Indeed, isolatingan organism from the clinical specimen is the first step in proving its roleas an etiologic Culturing bacteria is also the initial step in studying its morphology and Bacteria have to be cultured in order to obtain antigens from developingserological assays or Certain genetic studies and manipulations of the cells also need that bacteriabe cultured in Culturing bacteria also provide a reliable way estimating their numbers(viable count).
Differential media or indicator media distinguish one microorganism type from another growing on the same media. This type of media uses the biochemical characteristics of a microorganism growing in the presence of specific nutrients or indicators (such as neutral red, phenol red or methylene blue) added to the ...
