Histochemical Study of the Progenetic Trematode Alloglossidium renale
Figure 1
Harris hematoxylin staining of mature Alloglossidium renale within the host. (a) Overview of the parasite. The host antennal gland tubules are on the left side of the image and host striated muscle is on the lower right. (b) An enlargement of (a). (c) Area showing the compression of host antennal gland tubules with compacted nuclei (arrow). The parasite integument has an outer anucleate syncytium (arrowhead). (d) The parasite has consumed the antennal gland. Host muscle is located in the lower part of the image. The parasite integument is indicated (arrowhead). AG: antennal gland; I: intestine; L: Lumen of antennal gland tubule; and OS: oral sucker. (a) Bar = 200 μm, (b) bar = 100 μm, and (c)–(d) bars = 50 μm.
