Decreased cellularity of the lymph nodes suggests a reduction in the number of cells within the lymph nodes. This is likely due to a decrease in the number of T cells in the lymph nodes, indicating a loss of homing of T cells to lymphoid tissue, which is a hallmark of Bordetella pertussis infection. The peripheral lymphocytosis could be explained by the release of lymphocytes from the lymph nodes into the peripheral circulation.
