Reveal answer Fill a bubble to check yourself
E Correct answer
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 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
