Most laboratory testing and phenotypic trying methods specify use of a particular medium for growth of any organism to be tested.This helps insure accurate comparison of an unknown to databases of known organisms all grown on that same medium. A change away from animal-based media could have real implications for microbial testing laboratories,since changes in media composition could lead to altered physiological response by the microorganisms resulting in phenotypic changes that could result in misidentification of an isolate.Thus,if vegetable-based media are to supplant animal-based media,it is important to determine if they still yield reliable identifications using standard microbiological testing methods as well as strain identification platforms built on phenotypic databases.
