spironucleus vortens n sp from the freshwater angelfish pterophyllum scalare morphology and culture
Journal of Eukaryotic Microbiology, 1995Co-Authors: Sarah Louise Poynton, William A Fraser, Ruth Francisfloyd, Phillip Rutledge, Peggy Reed, Thomas A NeradAbstract:ABSTRACT. A new diplomonad flagellate, Spironucleus vortens n. sp., is described from the intestinal lumen of the freshwater angelfish, (Pterophyllum scalare), bred in Florida. Live organisms are pyriform, and measure 12.5–20.5 μm long by 5.0–11.2 um wide. Scanning electron microscopy shows that the trophozoite bears two compound lateral longitudinal ridges, each originating posterior to three emerging anterior flagella, and continuing posteriorly to the emergence of the posterior flagellum. Each ridge comprises a broad central part, surrounded by a peripheral ridge. At the opening of the flagellar pocket, the broader right peripheral ridge crosses to the other side of the body, and then back again. The posterior end of the body bears two papillae. Transmission electron microscopy shows that the compound lateral ridges are supported by microtubules, and bear microfibrillar structures in discrete longitudinal plaques. The serendipitous growth of S. vortens in a culture system with Lip Tumor tissue, facilitated axenic cultivation in a modified TYM medium (trypticase, yeast extract, maltose). The flagellate is now routinely maintained in an axenic TYI-S-33 medium (trypticase, yeast extract, iron serum), and is stabilized in the cryopreserved state. Spironucleus vortens is an aerotolerant anaerobe that can be cultured at 25° C, 28° C and 30° C.
