C. Lepromatous leprosy
Leprosy, also known as Hansen disease, constitutes a bacterial infection by either Mycobacterium leprae or M lepromatosis. The bacterium is an acid-fast bacillus that is typically slow growing, with a predilection for growth within macrophages, endothelial cells, and Schwann cells. Humans are primary carriers of the bacterium; however, 9-banded armadillos are a well-known reservoir of M leprae within North and South America. Individuals at risk of contracting the disease include those with close contact with an infected individual, exposure to armadillos, and immunosuppression or immunodeficiencies. The HLA-DQ1 gene has been implicated in persons more likely to develop the lepromatous form.1
