Description:This inoculated blood agar base plate cultivated colonial growth of Gram-negative, rod-shaped and facultatively anaerobic Serratia marcescens bacteria.
S. marcescens is an opportunistic pathogen, which means that it is usually not a cause of disease, however, under immunocompromised circumstances this bacterium can be found the culprit responsible for nosocomial infections such as endocarditis and pneumonia. This bacterium has also been found to be an infrequent cause of nosocomial, or hospital-acquired infections.

The culturing of a new organism using differing agar media, photomicrographs, and chemical analyses are all used in the taxonomic investigative process, which results in the placement of each organism into its appropriate taxonomic niche.
