Question

The bacteriostatic antibiotic is:
A. Tetracycline
B. Aminoglycosides
C. Penicillin
D. Ofloxacin

Answer 1

Hint- In order to find the required answer first we have to understand the term bacteriostatic antibiotic, furthermore we will see bactericidal agents and according to it we will get the answer.

Complete step-by-step answer:
Bacteriostatic antibiotics limit the growth of bacteria by interfering with bacterial protein production, DNA replication, or other aspects of bacterial cellular metabolism. They must work together with the immune system to remove the microorganisms from the body. However, there is not always a precise distinction between them and bactericidal antibiotics; high concentrations of some bacteriostatic agents are also bactericidal, whereas low concentrations of some bactericidal agents are bacteriostatic. This group includes:

Chloramphenicol
Clindamycin
Ethambutol
Lincosamides
Macrolides
Nitrofurantoin
Novobiocin
Oxazolidinone
Spectinomycin
Sulfonamides
Tetracyclines
Tigecycline
Trimethoprim

Hence the bacteriostatic antibiotic out of the given option is Tetracycline.
So, the correct answer is option A.

Additional information-
Penicillins are a group of antibacterial drugs which target a vast array of bacteria. These became the first such medicines that physicians used. Penicillin development and manufacturing has transformed the face of medicine, because these medicines have saved millions of lives.

Penicillin was the first antibiotic used by physicians.
Penicillin class includes several antibiotics.
Researchers attribute the discovery of penicillin to Alexander Fleming.
Penicillin acts by interacting with the cell walls of bacteria.
More than 1 percent of people are resistant to penicillin badly.

Note- A bacteriostatic agent is a biological or chemical agent that inhibits the replication of bacteria, though not necessarily killing them. Bacteriostatic antibiotics, disinfectants, antiseptics, and preservatives can be classified according to their use.
By using bacteriostatic antimicrobials the therapy time must be adequate to allow pathways of host defense to eliminate the bacteria. Once the bacteriostat is extracted, the bacteria normally start developing again. It is unlike bactericides which destroy bacteria.
