Erection of Ceratonova n. gen. (Myxosporea: Ceratomyxidae) to encompass freshwater species C. gasterostea n. sp. from threespine stickleback (Gasterosteus aculeatus) and C. shasta n. comb. from salmonid fishes.
Ceratonova gasterostea n. gen. n. sp. is described from the intestine of freshwater Gasterosteus aculeatus L. from the Klamath River, California. Myxospores are arcuate, 22.4 ± 2.6 μm thick, 5.2 ± 0.4 μm long, posterior angle 45° ± 24°, with 2 sub-spherical polar capsules, diameter 2.3 ± 0.2 μm, which lie adjacent to the suture. Its ribosomal small subunit sequence was most similar to an intest...

متن کاملChanges in the ultrastructure of gall bladder epithelium in rabbits with experimental gallstones.
The mucus-secreting activity of the gall bladder epithelium is normally subject to species variation (Hayward, 1968). Electron microscopic studies indicate definite evidence of secretory material in human gall bladder epithelial cells (Wolf-Heidegger, Staubli, and Hess, 1965), but there is no histological or ultrastructural evidence for mucus secretion in the rabbit gall bladder under normal co...
