Figure 1From: Free-living ciliates as potential reservoirs for eukaryotic parasites: occurrence of a trypanosomatid in the macronucleus of Euplotes encysticus1–6. General morphology and nuclear apparatus of infected and uninfected Euplotes encysticus Ind3. 1. Ventral view of the ciliate, fixed unstained specimen, DIC contrast. 2. Ventral view of the ciliate, silver-nitrate impregnation. 3. Dorsal view of the ciliate, fixed unstained specimen, DIC contrast. 4. Dorsal view of the ciliate, silver-nitrate impregnation. 5. Feulgen-staining of uninfected macronucleus. 6. Feulgen-staining of infected macronucleus. Dramatic changes in organelle shape are well visible. Ma, macronucleus; Mi, micronucleus. Bars = 15 μm (1, 3), 10 μm (2, 4, 5, 6).Back to article page
