A pathogen which cannot be cultured on nutrient medium is
Open in App
Solution
The correct option is C Virus
Culture medium or growth medium is a liquid or gel designed to support the growth of microorganisms. The most common growth media are liquid. These are often mixed with agar and poured into Petri dishes to solidify. These agar plates provide a solid medium on which microbes may be cultured. Some organisms, termed fastidious organisms, need specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells. Hence., viruses cannot be cultured in the nutrient medium. Thus, the correct answer is option C.
