hematopoietic system
• although lymphocyte numbers were generally normal, occasional animals had increased T cell and NK cell numbers together with decreased B cell numbers in the spleen
• tendency for T-cell proliferation to be increased even in the absence of infection
• biased toward the production of the Th1 cytokines Il-2 and IFN-gamma
• biased toward decreased production of the Th2 cytokine Il-4
• although levels of IgM, IgG, and IgA were normal, IgE levels were reduced

• although levels of IgM, IgG, and IgA were normal, IgE levels were reduced
• elevated T-cell response to Toxoplasma gondii infection
• lower titers of Ig isotypes directed against Toxoplasma antigens
• increased T-cell response to infection with lymphocyte choriomeningitis virus (LCMV)
• Elevated activity of CD8+ cytotoxic T lymphocytes in spleen
• CD4+ cells also increased 2-3X
• decrease in antibody secreting cells in spleen and bone marrow
• more virulent strains led to increased morbidity
