- A.
Aspergillosis
- B.
Coccidioides immitis
- C.
Nocardiosis
- D.
Moniliasis
Correct Answer
C. NocardiosisExplanation
Nocardiosis is a mycotic disease that can resemble tuberculosis but can be distinguished by the absence of hilar lymph node involvement. Nocardiosis is caused by a bacteria called Nocardia, not a fungus like the other options. It primarily affects the lungs, causing symptoms similar to tuberculosis such as cough, chest pain, and difficulty breathing. However, unlike tuberculosis, nocardiosis does not typically involve the hilar lymph nodes, which are located in the chest near the lungs. Therefore, the lack of hilar lymph node involvement helps differentiate nocardiosis from tuberculosis.Rate this question:
