Quizplus · Accepted Answer

The Ghon complex, also known as primary complex, is a characteristic lesion seen in the lungs of individuals infected with Mycobacterium tuberculosis. It is characterized by a small, well-circumscribed granuloma in the lung, often located in the mid to lower lung fields, and associated with regional lymphadenopathy. The Ghon complex is considered to be the hallmark of primary tuberculosis infection. Option B (Bacillus anthracis) is incorrect as it causes anthrax, which primarily affects the skin, lungs or gastrointestinal system, but not the Ghon complex. Similarly, options C and D are incorrect as they cause fungal infections and are not associated with the Ghon complex.
