Blue-green pus in burns patients is indicative of —— cellulitis
**Core Concept**
Blue-green pus in burns patients is indicative of a specific type of cellulitis caused by the bacterium Pseudomonas aeruginosa. This bacterium thrives in moist environments and is commonly found in burn wounds, leading to a characteristic blue-green discharge.
**Why the Correct Answer is Right**
Pseudomonas aeruginosa produces pigments such as pyocyanin, which is responsible for the blue-green color of the pus. This bacterium also produces enzymes that break down tissue and contribute to the progression of cellulitis. The moist environment of burn wounds provides an ideal breeding ground for Pseudomonas aeruginosa, leading to infection.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the bacterium responsible for the blue-green pus. While other bacteria may cause cellulitis, Pseudomonas aeruginosa is the primary culprit in burn patients.
**Option B:** This option is incorrect because Staphylococcus aureus is a common cause of cellulitis, but it does not typically produce blue-green pus.
**Option C:** This option is incorrect because Escherichia coli is a common cause of urinary tract infections, but it is not typically associated with blue-green pus in burn patients.
**Option D:** This option is incorrect because Klebsiella pneumoniae is a gram-negative bacterium that can cause pneumonia, but it is not typically associated with blue-green pus in burn patients.
**Clinical Pearl / High-Yield Fact**
Remember that Pseudomonas aeruginosa is a common cause of cellulitis in burn patients, and the presence of blue-green pus should raise suspicion for this bacterium.
**Correct Answer:** A. Pseudomonas aeruginosa
