Figure 1

Cellular analysis indicates absence of endosymbionts in Dracunculus species. Tissues from D. medinensis (A), D. lutrae (B) and D. insignis (C) were stained with propidium iodide as described [23] and compared to Wolbachia-harbouring Brugia malayi tissues (D). A, A’, B, D and C, lateral hypodermal cords (scale bar = 50 μm); B’, C’ and D’, embryos (scale bar = 10μm); A” and D”, microfilariae (scale bar = 50 μm). The bars at top left of the panels represent the length of half a cord. In panels A and A’, arrows point to smaller nuclei of about 4 μm, from tissue underlying the hypodermis. In panels D, D’ and D”, long arrows point to Wolbachia foci.
