| morphology of diplomonad flagellates: spironucleus torosa n. sp. from atlantic cod gadus morhua l., and haddock melanogrammus aeglefinus (l.) and hexamita salmonis moore from brook trout salvelinus fontinalis (mitchill). | a diplomonad flagellate, spironucleus torosa n. sp. is described from atlantic cod gadus morhua and haddock melanogrammus aeglefinus. this is believed to be the 1st confirmed report of spironucleus from a marine fish. organisms swimming in the rectal lumen were broadly pyriform to elongate, and measured 10.5-18.6 microns long and 3.2-13.3 microns wide; other elongate organisms were attached to the rectal epithelium, via apical extensions appearing continuous with the microvilli. the posterior en ... | 1990 | 2213651 |
| electron microscopical identification of the flagellate spironucleus torosa (hexamitidae) from burbot lota lota (gadidae) with comments upon its probable introduction to this freshwater host. | hexamitid flagellates from the rectum of the freshwater gadid burbot, from the river glomma in southeastern norway, were studied by scanning and transmission electron microscopy. the surface morphology of the flagellates was consistent with that of spironucleus torosa, previously only found in the cod, haddock, and saithe, all marine gadids. posteriolateral depressions with central protrusions were present in the flagellates, a feature reported from s. torosa only. further, the microtubular cyto ... | 1998 | 9794636 |
| phylogeny of spironucleus (eopharyngia: diplomonadida: hexamitinae). | diplomonad flagellates from the genera spironucleus and hexamita (hexamitinae) inhabit the digestive tract of a variety of animal hosts, some as important pathogens, and others as commensals. species descriptions of many diplomonads have been based on light microscopy only, causing many taxa to be misidentified. presently, electron microscopy is considered the appropriate tool for description of diplomonads. the existence of morphologically very similar genotypes/species has in addition prompted ... | 2007 | 17292667 |
