An Infant with Recurrent Bacterial and Fungal Infections Is Suspected

question 7

Multiple Choice

An infant with recurrent bacterial and fungal infections is suspected to have an immunodeficiency disease. Within two days after exposure to a pathogen, the organisms have proliferated to dangerous levels requiring immediate systemic antibiotic treatment. It is unlikely that this infant has a defect in B or T lymphocyte responses to the infection because:

• A) Bacteria and fungi do not require B cell or T cell responses for their clearance.
• B) Bacteria and fungi are not efficiently transported to draining lymph nodes to initiate adaptive immune responses.
• C) Systemic infections of bacteria and fungi are usually cleared by the spleen.
• D) The defective immune response occurs too rapidly following infection to be due to a defect in B or T lymphocytes responses.
• E) Adaptive immune responses require dendritic cells to take up and degrade pathogens.
