-》 The broad-spectrum antibiotic refers to an antibiotic that acts against a wide range of disease-causing bacteria. A broad-spectrum antibiotic act against both Gram-positive and Gram-negative bacteria, in contrast to a narrow-spectrum antibiotic, which is effective against specific families of bacteria. An example of a commonly used broad-spectrum antibiotic is ampicillin.
•Thus, the correct answer is option D.

Which one of the following is not true about antibioticsa)First antibi...
Explanation:
The correct answer is option D - Each antibiotic is effective only against one particular kind of germ.
Explanation:
Antibiotics are drugs that are used to treat bacterial infections. They work by killing or inhibiting the growth of bacteria. Here is a detailed explanation of each statement to understand why option D is not true.
Statement A: First antibiotic was discovered by Alexander Fleming
This statement is true. Alexander Fleming, a Scottish biologist, discovered the first antibiotic, penicillin, in 1928. He noticed that a mold called Penicillium notatum produced a substance that killed bacteria.
Statement B: The term antibiotic was coined by S. Waksman in 1942.
This statement is also true. Selman Waksman, an American microbiologist, coined the term "antibiotic" in 1942. He defined antibiotics as substances produced by microorganisms that inhibit the growth of other microorganisms.
Statement C: Some persons can be allergic to a particular antibiotic
This statement is true. Allergies to antibiotics are quite common. Some individuals may develop an allergic reaction, such as a rash, itching, or swelling, when they are exposed to specific antibiotics. It is important to be aware of any known allergies before starting antibiotic treatment.
Statement D: Each antibiotic is effective only against one particular kind of germ
This statement is not true. While some antibiotics are effective against a specific type of bacteria, many antibiotics have a broader spectrum of activity and can be effective against multiple types of bacteria. For example, penicillin is effective against a wide range of Gram-positive bacteria. Similarly, tetracycline is effective against both Gram-positive and Gram-negative bacteria. Therefore, antibiotics can target various types of bacteria depending on their mechanism of action.
In conclusion, option D is the correct answer as it states that each antibiotic is effective only against one particular kind of germ, which is not true. Antibiotics can have a broader spectrum of activity and can target multiple types of bacteria.
The correct answer is option D - Each antibiotic is effective only against one particular kind of germ.
