Counts, relative to those of the living lymphocyte population, of CD2+ T and NK cells, CD8high cytotoxic T cells, CD4+ T helper cells, and IgM-positive (IgMpos) B cells in ileal lymph nodes (IL LN) 42 days after S. Typhimurium infection of 12 piglets fed a low-Zn (LZn) diet (60 to 80 mg Zn/kg as ZnO), 12 piglets fed a medium-Zn (MZn) diet (150 mg Zn/kg as ZnO), and 11 piglets fed a high-Zn (HZn) diet (2,500 mg Zn/kg as ZnO). Each dot represents the finding for one animal. Each horizontal line indicates the median for the animals in one feeding group. Plus signs indicate a tendency (0.05 < P < 0.1); asterisks indicate significant differences (*, 0.01 < P < 0.05; **, 0.001 < P < 0.01; ***, P < 0.001).
