Question

The term broad spectrum antibiotics means:
A.Bactericidal antibiotics
B.Bacteriostatic antibiotics
C.Which kill or inhibit a wide range of gram -ve and gram +ve bacteria
D.Which kill or inhibit all types of gram +ve bacteria

Answer 1

Hint: We must remember that the antibiotics substance are those substances which are active against bacteria. They are widely used for medicinal purposes due to their unique properties. Drugs which inhibit growth or effect of viruses are called as antiviruses which is different from antibacterial and antibiotics.

Complete answer:
We have to know that the antibiotics are used to kill or inhibit growth of bacteria in a living body. Antibiotics are classified as broad spectrum and narrow spectrum antibiotics. Antibiotics are referred to as antibacterials.
The broad spectrum antibiotics or antibacterial is further classified as a large number of gram positive and gram negative antibiotics or antibacterial.
This classification of bacteria comes into the picture when the bacteria and its effect is known but the group of bacteria is unknown. The bacterial structure can be of different types such as cocci, diplococci, bacilli, etc. Depending upon the shape the different antibiotics are used to act on different bacterias.
Examples of broad spectrum antibiotics are – ampicillin, azithromycin (used to cure throat infection), amoxicillin, piperacillin, etc.
Hence, according to the theory, the correct answer to the question is option C. – which kills or inhibits a wide range of gram negative and gram positive bacteria.

Note:
We must know that antibiotics are widely used for medical purposes due to their healing properties. It acts as a killing agent for bacteria, thus helping to cure disease or reduce the effect of bacteria. We must remember that the antibiotics are not effective against viruses such as common cold or influenza.
