Question

Consider the following:BacteriaFungiVirusWhich of the above can be cultured in artificial/synthetic medium?

Accepted Answer

Correct Answer: A — 1 and 2 onlyStep-by-step Solution:Bacteria: Can be cultured on artificial nutrient media (agar plates, broths) as they are independent organisms that can synthesise or absorb required nutrients. ✓Fungi: Many fungi can be cultured on synthetic media (e.g., potato dextrose agar) as they are saprophytes or parasites that can grow on organic substrates. ✓Virus: Cannot be cultured on artificial media because they are obligate intracellular parasites. They require living host cells (eukaryotic or prokaryotic) for replication. Viral culture is done in cell lines, embryonated eggs, or live animals. ✗Why other options are incorrect:Option B (2 and 3): Viruses cannot be cultured on artificial media.Option C (1 and 3): Viruses cannot be cultured on artificial media.Option D (1,2,3): Viruses cannot be cultured on artificial media.Key Concept: Microbiological culture techniques are essential for studying microorganisms. Louis Pasteur and Robert Koch developed culture methods. Viruses require host cells; this is why viral diseases are harder to diagnose via culture. PCR and other molecular methods are now used.
