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 are not efficiently transported to draining lymph nodes to initiate adaptive immune responses.
B) Systemic infections of bacteria and fungi are usually cleared by the spleen.
C) Bacteria and fungi do not require B cell or T cell responses for their clearance.
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.

the correct options would be:

E) Adaptive immune responses require dendritic cells to absorb and degrade pathogens.

A) Bacteria and fungi are not efficiently transported to draining lymph nodes to initiate adaptive immune responses.

Explanation:

Both options are valid since there may be an alteration in the presentation of antigens by phagocytic cells such as dendritic cells or macrophages, or there could also be an alteration in the pathway to the lymph nodes, where lymphocytes cannot be achieved. Present to said antigenic molecule that I present the phagocytic cells and therefore the specific antibody is never manufactured in the ganglion.

Both moments of immunity may be affected, which I see as more likely to be the phagocytic cell, but failure of antigen conduction to the ganglion should not be ruled out for the synthesis of specific antibody in order to comply with the IMMUNE RESPONSE ACQUIRED , that is, the one that is ACQUIRED throughout life since we are not born with it
