## **Core Concept**
Rabies is a viral infection caused by the rabies virus, which affects the central nervous system (CNS). The disease is characterized by inflammation of the brain, leading to a range of clinical manifestations. A key pathological feature of rabies is the presence of **Negri bodies** in the neurons.

## **Why the Correct Answer is Right**
The correct answer, **Negri bodies**, are characteristic pathological inclusions found in the neurons of individuals infected with the rabies virus. These bodies are named after Adelchi Negri, who first described them. Negri bodies are eosinophilic, cytoplasmic inclusions that are pathognomonic for rabies. They are typically found in the hippocampus, cerebellum, and brainstem. The presence of Negri bodies is a diagnostic hallmark of rabies.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it is not specified, but based on the context, it is clear that Negri bodies are the correct answer.
- **Option B:** This option is incorrect because it is not specified, but it does not correspond to Negri bodies.
- **Option C:** This option is incorrect because it is not specified, but it does not correspond to Negri bodies.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for rabies is that **Negri bodies are pathognomonic** for the disease. Their presence confirms the diagnosis of rabies. It's also important to note that while Negri bodies are highly suggestive of rabies, their absence does not rule out the disease, as they may not be present in all cases.

## **Correct Answer:** . Negri bodies
