Description of Rhynchopus euleeides n. sp. (Diplonemea), a Free‐Living Marine Euglenozoan

Abstract: We describe Rhynchopus euleeides n. sp., using light and electron microscopy. This free-living flagellate, which was isolated earlier from a marine habitat, can be grown axenically in a rich medium based on modified seawater. In the trophic stage, cells are predominantly elliptical and laterally flattened, but frequently change their shape (metaboly). Gliding is the predominant manner of locomotion. The two flagella, which are typically concealed in their pocket, are short stubs of unequal length, have convent… Show more

“…Aerobic kinetoplastids and euglenids possess well-developed discoid-shaped cristae within their mitochondria [26], and diplonemids and Hemistasia possess a few flat-shaped cristae within each mitochondrion [30-32]. By contrast, both C. aureus and P. mariagerensis lack recognizable mitochondria with cristae, and instead, contain double-membrane bound organelles that are nearly identical in morphology to the well-studied hydrogenosomes described in other anoxic flagellates (e.g.…”

“…Os organismos do filo Euglenozoa foram reclassificados com base em estudos filogenéticos moleculares em três classes: Kinetoplastea, composta por parasitas e comensais de plantas e animais; Euglenoidea, que compreende apenas organismos de vida livre e Diplonemea, que compreende organismos de vida livre e ocasionalmente parasitas facultativos. A classe Kinetoplastea compreende duas subordens, Tripanosomatina e Bodonina (Dolezel et al, 2000;Preisfeld et al, 2001;Moreira et al, 2001;Busse e Preisfeld, 2002;Simpson e Roger, 2004;Von der Heyden et al, 2004;Roy et al, 2007;Breglia et al, 2007).…”

“…Esses organismos apresentam ainda como principais características: o cinetoplasto; a composição do citoesqueleto; os glicossomas; proteínas de membrana ancorada por GPI; a endocitose e exocitose de macromoléculas via bolso flagelar, o nucleotídeo denominado base J em seu DNA nuclear; variação antigênica; etc. Algumas destas características são compartilhadas com os diplonemídeos e euglenídeos (Vickerman, 1994;Dooijes et al, 2000;Gull, 2001;Simpson et al, 2003;Campbel et al, 2003;Uliel et al, 2004;von der Heyden et al, 2004;Lukes et al, 2005;Michel et al, 2006;Roy et al, 2007;. Os tripanossomatídeos, principalmente os de ciclo heteroxênico, vivem em diferentes hospedeiros e ambientes durante seu desenvolvimento.…”
