Pikes medium is for:
**Core Concept**
Pike's medium is a selective culture medium used in microbiology to isolate and differentiate between different types of Neisseria species, particularly Neisseria gonorrhoeae and Neisseria meningitidis. The medium is designed to favor the growth of these pathogens while inhibiting the growth of other bacteria.
**Why the Correct Answer is Right**
The correct answer is related to the selective growth of Neisseria species on Pike's medium. This medium contains various components that inhibit the growth of other bacteria, such as Gram-positive cocci, while allowing Neisseria species to thrive. The medium's composition, including the presence of V factor (nicotinamide adenine dinucleotide, NAD) and X factor (hemin), provides the necessary nutrients for the growth of Neisseria species.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct use of Pike's medium. While it may be related to the medium, it is not the primary use.
**Option B:** This option is incorrect because it is not a well-known application of Pike's medium. The medium is not typically used for this purpose.
**Option C:** This option is incorrect because it does not accurately describe the use of Pike's medium. The medium is not used for this specific application.
**Clinical Pearl / High-Yield Fact**
Pike's medium is an example of a selective culture medium used in microbiology to isolate and differentiate between different types of Neisseria species. This medium is an important tool in the diagnosis and treatment of infections caused by these pathogens.
**Correct Answer: D.**
