S1 Data -

Contains the data from which tables and figures have been constructed: Tab A. Data for Table 1. Mean and SD of body and brain weights of control gerbils and gerbils inoculated with trophozoites of two isolates: HGINV and WB. Tab B. Data for Fig 1. Mean and SD of zinc in tissues from control and inoculated gerbils with two isolates of Giardia intestinalis: WB and HGINV. A significant decrease was present in zinc levels. Tab C. Data for Fig 3. Representative photomicrographs of the cerebellum of control and Giardia intestinalis parasitized gerbils; Cresyl Violet stain. Thickening (mean and SD) of the external granule layer (EGL) is evident in 14 and 21 day-old parasitized gerbils. Tab D. Data for Fig 4. Estimation of Purkinje neurons in mid-sagittal slices of the cerebellum of control and Giardia intestinalis parasitized gerbils by Cresyl violet staining (Normal) and the TUNEL technique (mean and SD). Tab E. Data for Table 2. Mean and SD of TUNEL-positive pyramidal neurons in CA1 and CA3 regions of the hippocampus and Table 3. Mean and SD of TUNEL-positive granular cells in the DG. (XLSX)
