^*Animal nos. 1–12 were from experiment no. 1 and animals nos. 23–24, 26–35 were from a confirmatory experiment (no. 2) as described in Materials and Methods. F, female, M, male. 

^†In most cases at killing or death, the following tissues were taken for histology and PCR analysis: abbreviations; SPL, spleen; BM, bone marrow (femur); THY, thymus; LN, lymph node. Brain, lung, and kidney also were sampled but none were positive by PCR-SB and so are not included in the table.
