Which of the following antibiotic is active against fungus ?
- Polyenes
- Streptomycin
- Neomycin
- Tetracyclin
The Correct Option is A
Solution and Explanation
Answer (a) Polyenes.
Polyene is used as an antibiotic against fungi and is used for the treatment of fungal infection. The most commonly used antifungal purpose is amphotericin B. It is effective for many fungal species. It will bind to the cell membrane of fungi by interacting with ergosterol present in the membrane. This will affect and disturb the integrity of the cell wall thus leading to death.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
