Question

Which one of the following antibiotics is made from bacteria?
A) Streptomycin
B) Tetracycline
C) Vancomycin
D) All of the above

Answer 1

Most of the antibiotics are obtained from microorganisms like bacteria. These antibiotics obtained from bacteria are not helpful in curing viral infection. They work by either killing the bacteria or inhibiting its growth.

Complete answer:
Antibiotics are medicines that work against harmful pathogens that infect the human body. They identify the pathogen and make antibodies against it so that it doesn’t grow and multiply. These antibiotics can be taken orally or by injecting it directly into the body.

Let us know each antibiotic and identify whether they are made from bacteria or not –
Streptomycin- it is obtained from the bacteria Streptomyces griseus. It is helpful in curing various diseases like tuberculosis, endocarditis, mycobacterium avium etc. It is administered into the body through injection into veins or muscles. It’s side-effects include- vertigo, vomiting, numbness of face, fever and rashes. It should not be given to pregnant women as it may lead to deafness in the newborn. It should not be given to people with neuromuscular disorders.

Tetracycline- it was discovered by Benjamin Minge Duggar. It is extracted from the bacteria Streptomyces aureofaciens and Streptomyces rimorous. It is helpful in curing a variety of infections including stomach ulcers and face acne. It works by inhibiting the growth of bacteria. It works best if taken one-hour before the meal or two hours after the meal.

Vancomycin- it was discovered by Eli lilly and company. It was isolated from the bacteria Streptomyces orientalism. It is helpful in curing skin related infections, bone infections, lower respiratory tract infections. It’s side effects include diarrhea and stomach pain.

Thus the correct answer is option ‘D’.

Note:
- Using an antibiotic when there is no infection then, it may be of no use to the individual in the future when he/she is infected with the disease.
- Stopping an antibiotic too early may lead to the growth and multiplication of the bacteria again. So, one must consult a doctor before stopping using it.
