Question

Most widely used bioweapon is?
A.Bacillus subtilis
B. Pseudomonas putida
C. Bacillus anthracis
D. None of these above

Answer 1

Hint: B.Anthracis spores are almost indestructible and persist as viable even after being exposed to extreme temperatures and ultraviolet radiation. Their spores are light, odorless, colorless, and can easily contaminate a large population rapidly. Also, it is hard to detect. Hence, B.Anthrax gives rise to the perfect deadly biological weapon.

Complete answer:
> Option (A) - Bacillus subtilis
It is also known as the hay bacillus or grass bacillus. It is a Gram-positive, and catalase-positive bacteria. It is found in soil and the gastrointestinal tract of ruminants and humans. It belongs to the genus Bacillus.

> Option (B) - Pseudomonas putida
It is a Gram-negative, rod-shaped, and saprotrophic soil bacterium. P. putida was taxonomically confirmed to be a Pseudomonas species (sensu stricto), Based on 16S rRNA analysis. It gets its name because It is placed, along with various other species, in the P. putida group.

> Option (C) - Bacillus anthracis
Bacillus anthracis causes the disease anthrax which is a common disease of livestock and, sometimes, of humans. It is the only obligate pathogen within the genus Bacillus. This disease is classified as a zoonosis, causing infected animals to transmit the disease to humans.

Hence, The correct answer is option (C).

Note: Biological warfare is also known as germ warfare. It is a war in which, use of biological toxins or infectious agents like bacteria, viruses, insects, and fungi are used with the purpose to kill or injure humans, animals, or plants. These are known as biological weapons as they are living organisms or replicating entities.
