Cultivation is essential for several reasons: 1. Identification of Pathogens: By isolating and growing pathogens in the laboratory, epidemiologists can accurately identify the causative agents of infectious diseases. 2. Understanding Disease Mechanisms: Cultivation allows researchers to study how pathogens interact with host cells, how they cause disease, and how they evade the immune system. 3. Antibiotic Sensitivity Testing: Cultivating pathogens enables the testing of various antibiotics to determine the most effective treatment options. 4. Vaccine Development: Studying cultivated pathogens helps in developing vaccines by identifying potential targets for immunization. 5. Epidemiological Surveillance: Cultivation aids in monitoring the spread of infectious diseases and detecting emerging pathogens.
