Question

An anaerobe causing multiple abscess with discharging sinuses, demonstrating sulphur granules in pus is?

• A. Actinomycetes
• B. Nocardia
• C. Salmonella
• D. Tularemia

Answer 1

The Correct Option is A

The question involves identifying an organism based on the clinical presentation of multiple abscesses with discharging sinuses and the presence of sulfur granules in pus.

Given the options:

• Actinomycetes
• Nocardia
• Salmonella
• Tularemia

We evaluate these options:

1. Actinomycetes: These are a group of filamentous bacteria that are known to cause a condition called Actinomycosis. This condition is characterized by the formation of multiple abscesses and sinus tracts that can discharge sulfur granules. The presence of these granules is a hallmark of Actinomycosis.

2. Nocardia: While also causing abscesses and lesions, Nocardia species typically do not produce sulfur granules.

3. Salmonella: A genus of bacteria generally associated with gastrointestinal infections and less commonly with extraintestinal infections. It does not produce granulomatous lesions with sulfur granules.

4. Tularemia: Caused by Francisella tularensis, this condition does not involve sulfur granules in its presentation.

Based on the classic presentation with sulfur granules, the correct answer is Actinomycetes.
