The COVID-19 Virus was deemed As DNA Virus

Yeasts are unicellular fungi that reproduce primarily through a process called budding, in which a small daughter cell forms as an outgrowth of the parent cell and eventually detaches. Some yeasts can also reproduce by fission, but budding is the most common method. Yeasts differ from molds, which are multicellular and form filamentous hyphae. As unicellular organisms, yeasts are capable of rapid growth in nutrient-rich environments and are responsible for both beneficial processes, such as fermentation in food and beverage production, and pathogenic infections in humans.

A. Ehrlich: Paul Ehrlich is known for his work in immunology and chemotherapy, including the development of the concept of the “magic bullet” and the discovery of salvarsan for treating syphilis. While his work advanced the understanding of targeted therapies, he was not the first to develop vaccines.

B. Jenner: Edward Jenner is credited with developing the first successful vaccination. In 1796, he inoculated a boy with material from cowpox lesions and demonstrated that it conferred immunity against smallpox. This pioneering work established the principle of using a related, less virulent pathogen to prevent disease.

C. Lister: Joseph Lister introduced antiseptic surgery using carbolic acid to reduce postoperative infections. His contributions advanced surgical safety but did not involve the development of vaccines or active immunization.

D. Koch: Robert Koch provided experimental proof that specific microbes cause specific diseases through Koch’s postulates. While foundational in microbiology, he did not develop vaccines.

E. Escherich: Theodor Escherich discovered Escherichia coliand contributed to bacteriology and pediatric infectious disease research. His work focused on bacterial identification, not vaccination.
