Random amplified polymorphic DNA analysis results using primer B12 on B, J, and Q lineage tachyzoites. Lanes 1 and 9, 123 bp marker; lanes 2 and 3, B lineage passes 21 and 79; lanes 4 and 5, Q lineage passes 22 and 78; lanes 6 and 7, J lineage passes 21 and 79; lane 8, uninfected cell control. Reproducible Toxoplasma gondii specific products (absent in uninfected cell control) of 243 bp and 584 bp are identified. *Other T gondii specific bands not found in at least four of the six RAPD runs, and were thus not included in the final analysis.
