Question

Antibiotics are mostly obtained from
A) Bacteria
B) Viruses
C) Angiosperms
D) Fungi

Answer 1

Hint: Antibiotic development is naturally present in the body that can now be repeated and enhanced in laboratory environments due to advancements in research. Large-scale medicinal development of antibiotics has been made easier due to the discovery of penicillin by Alexander Fleming, and the actions of Chain and Florey in 1938.

Complete Answer:
A type of antimicrobial substance that is active against bacteria is an antibiotic. It is an essential form of antibacterial agent that is used to fight bacterial infections, and in the treatment and prevention of infections, antibiotic medications are commonly used. They may either destroy the bacterial growth or prevent it. A limited number of antibiotics have antiprotozoal activity as well.

Now, let us find the solution from the options-
- Antibiotics are substances produced by an organism and inhibit another organism’s development. They are collected directly from bacteria. They are used to protect against contamination by bacteria. They are, however, not suitable for viral infections. By either removing bacteria or stopping their replication, they function.
- Bacteria are separate from viruses; they have a different form and a different means of survival. Viruses do not have antibiotic-attackable cell walls; they are instead covered by a protective protein layer. Thus, option B is not the correct option.
- Angiosperms are the most commonly produced flowering plants which are modified to render them less vulnerable to nutrition and space competition; they do not contain antibiotics. Thus, option C is not the correct option.
- Alexander Fleming identified the antibacterial effects of penicillin in 1929. He observed that on an agar plate streaked with the Staphylococcus aureus bacterium, a fungal colony had emerged as a contaminant but that the bacterial colonies all around fungus were visible because of the lysing of their cells. Fleming dedicated much of his work to discovering ways to cure wound infections and realized quickly the value of a fungal metabolite that could be used to manage bacterial infections. Thus, option D is not a correct option.

Thus, the correct answer is option (A) Bacteria.

Note: It is possible to divide antibiotic development into 3 techniques: natural fermentation, synthetic and semi-synthetic. Research and development of new antibiotics continues to be relevant as more and more bacteria begin to develop resistance to antibiotics currently developed.
