Question

Maximum number of antibiotics got from any group is
A) Actinomycetes
B) Fungi
C) Eubacteria
D) Viruses

Answer 1

Hint:Antibiotics are the medicines that kill the bacteria or stop the growth of the bacteria. They help in treating the infections that are caused by the bacteria. The word antibiotic means ‘against life’.

Complete answer:
Maximum numbers of antibiotics are produced from the Eubacteria among all the given groups.Eubacteria are the ‘true bacteria’.They are the single celled prokaryotic organisms (organisms that have not well defined nucleus).All the eubacteria contain cell walls.Cell wall is made up of peptidoglycan in a cross linked chain pattern.For example – Streptomycin antibiotic.
Additional information:
Actinomycetes :-Actinomycetes are the members of the groups of gram positive bacteria.These bacteria are generally anaerobic bacteria.Actinomycetes belong to the order Actinomycetales.Actinomycetes are used in agroindustry as a source of biologically active compounds, biocontrol agents and PGPRs.Actinomycetes are the group of unicellular filamentous bacteria that form a branching network of filaments and produce spores.
Fungi :-Fungi belong to the eukaryotic organisms (organisms that have a well defined nucleus).They include yeast and molds as well as the mushrooms.All the fungi belong to the kingdom Fungi.Fungi such as Penicillium notatum is used to make antibiotics called penicillin.Fungi make antibiotics but in less number than that of the eubacteria.The cell walls of the fungi are made up of polysaccharides and chitin.
Viruses:-Viruses are the infectious agents that replicates only inside the living cells of the organism.Viruses can infect all types of organisms whether they are plants, animals, or bacteria.Viruses never produce antibiotics.The study of viruses is called virology.
Therefore, it has been clear from the above discussion that the maximum number of antibiotics got from any group is eubacteria.
Hence, option ‘C’ is the correct answer.


Note:Antibiotics can be used against many bacterial infections such as-
i) Some ear and sinus infection
ii) Dental infection
iii) Skin infection
iv) Strep throat
v) Bacterial pneumonias
vi) Whooping cough
vii) Bladder and throat infections, etc.
