## Core Concept
Glanders, also known as Farcy's disease, is a bacterial infection caused by a specific pathogen. It primarily affects the skin and mucous membranes and is more common in individuals who work with animals, particularly horses.

## Why the Correct Answer is Right
The causative organism of glanders is *Burkholderia mallei*. This bacterium is a gram-negative, aerobic, rod-shaped bacterium. It causes glanders, a disease that can manifest in acute or chronic forms, affecting the skin, lungs, and other organs. The bacteria can infect humans through direct contact with infected animals or contaminated animal products.

## Why Each Wrong Option is Incorrect
* **Option A:** *Burkholderia cepacia* is a bacterium that can cause infections, particularly in people with compromised immune systems or cystic fibrosis, but it is not the causative agent of glanders.
* **Option C:** *Pseudomonas aeruginosa* is a common pathogen in various infections, especially in immunocompromised patients and those with cystic fibrosis, but it does not cause glanders.
* **Option D:** *Streptococcus suis* is a pathogen that causes infections in pigs and can be transmitted to humans, leading to severe diseases, but it is not associated with glanders.

## Clinical Pearl / High-Yield Fact
A key point to remember is that glanders is a zoonotic disease, meaning it can be transmitted from animals to humans. Individuals at high risk include veterinarians, horse handlers, and laboratory workers who may come into contact with *Burkholderia mallei*.

## Correct Answer: B.
