Question

Quizplus · Accepted Answer

The tubercles or granulomas formed in primary tuberculosis are caused by an influx of mononuclear cells, mainly macrophages, to the site of infection. These macrophages engulf the Mycobacterium tuberculosis bacteria and present antigens to other immune cells, leading to the formation of the granuloma. Neutrophils and PMNs may also be present in the site of infection, but they are not the primary cause of the tubercles. Basophils and antibodies are not typically involved in the primary immune response to tuberculosis.
