An antibiotic such as penicillin

  1. Kills pathogenic bacteria

  2. Prevents pathogenic bacteria from reproducing

  3. Works against infectious viruses

  4. Inhibits the reproduction of retroviruses

  5. Both A and B


Correct Option: E
Explanation:
Antibiotics function by blocking vital processes in bacteria, killing the bacteria, or stopping them from multiplying. This helps the body's natural immune system to fight the bacterial infection. Antibiotics that affect a wide range of bacteria are called as broad spectrum antibiotics (e.g., amoxicillin and gentamicin). Antibiotics that affect only a few types of bacteria are called as narrow-spectrum antibiotics (e.g., penicillin). Penicillin is bactericidal. A bactericidal antibiotic usually either interferes with the formation of the bacterium's cell wall or its cell contents. A bacteriostatic antibiotic stops bacteria from multiplying. An antibiotic is given for the treatment of an infection caused by bacteria. Antibiotics target microorganisms such as bacteria, fungi and parasites. However, they are not effective against viruses.

The wonder drug penicillin was discovered by

  2. A denatured toxin

  3. Toxin produced by protozoa

  4. Inactive toxin.


Correct Option: D
Explanation:

A protoxin is an inactive toxin which is converted to an active form by the alkaline pH present in the gut of insects.

So, the correct option is 'Option D' .

Anti-toxins are used to induce

  1. Death

  2. Passive immunity

  3. Diseases

  4. None of the above


Correct Option: B

Antitoxin is a special type of

  1. Antibody

  2. Antigen

  3. Disease

  4. None of the above


Correct Option: A

The probiotic drinks such as 'Yakult' contains healthy bacterial suspension. They are used for boosting the immune system and strengthening the digestive systems. The mechanisms by which they do it might be by?

  1. By generating antibody against them

  2. By generating toxins which kill other bacteria

  3. They divide in the gut faster and replace the existing harmful bacteria

  4. They eat the harmful bacteria


Correct Option: B
Explanation:

Probiotics are live organisms intended to provide health benefits when consumed, generally by improving or restoring the gut flora (microorganisms present in the gut). Yakult is a delicious probiotic fermented milk drink that contains exclusive L.casei strain. Probiotics, when entered into the body generates toxins which help in the elimination of other harmful bacteria.

Thus, the correct answer is 'By generating toxins which kill other bacteria.'

Cause of death in snake bite cases usually involve

  1. Neurotoxicity

  2. Destruction RBC's

  3. Permanent contraction of muscles

  4. Both A and B


Correct Option: D
Explanation:

The best medicine for snake bite is 

  1. Antiseptic

  2. Antivenom

  3. Antibiotic

  4. Atreptomycin


Correct Option: B
