Question

Which arm of immune response plays an important role in controlling nocardiosis.

Q141 marks★✓

Answer

Cell-mediated immunity (CMI) plays the important role in controlling nocardiosis, since Nocardia species are facultative intracellular organisms — accordingly, impairment of cell-mediated immunity (e.g., in HIV/AIDS, organ transplant recipients on immunosuppressive therapy, chronic corticosteroid use) is the major risk factor predisposing to invasive/disseminated nocardiosis.
