A patient of peptic ulcer disease. When investigated endoscopically showed chronic antral gastritis. Which of the following dye will be able to stain the specimen?
**Core Concept**
The underlying principle being tested is the identification of **Helicobacter pylori** in gastric mucosa, which is a common cause of **peptic ulcer disease** and **chronic antral gastritis**. This requires the use of special stains to visualize the bacteria.
**Why the Correct Answer is Right**
The correct answer is related to the stain used to identify **Helicobacter pylori**. Since the correct answer is not provided, we'll proceed with the general knowledge that **Warthin-Starry stain**, **Giemssa stain**, or **Toluidine blue** can be used, but most commonly **Warthin-Starry stain** is used for this purpose due to its ability to stain the bacteria's spiral shape.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we can't comment directly, but if it's not related to **Helicobacter pylori** staining, it's incorrect.
**Option B:** Similarly, without specifics, if it doesn't relate to identifying **H. pylori**, it's not the right choice.
**Option C:** If this option is not a stain used for **H. pylori**, such as **Warthin-Starry**, it would be incorrect.
**Option D:** Again, without specifics, if it doesn't aid in identifying **H. pylori** in gastric mucosa, it's incorrect.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **Helicobacter pylori** infection is a major cause of **peptic ulcer disease** and **gastric cancer**, and its detection is crucial for appropriate management.
**Correct Answer:** Correct Answer: D. Warthin-Starry stain.
