“…However, the presence of a large kinetoplast (Fig. 1X), 868 nm in diameter, suggested a bodonid lineage (Maslov et al 2001). This flagellate isolate may represent an incertae sedis, as it is generally believed that trypanosomatids descended from within the bodonids (Luke$ et al 2004).…”

Protozoan isolates from the gills of marine-reared Atlantic salmon Salmo salar smolts were cultured, cloned and 8 dominant isolates were studied in detail. The light and electron-microscopical characters of these isolates were examined, and 7 were identified to the generic level. Structure, ultrastructure, a species-specific immunofluorescent antibody test (IFAT), and PCR verified the identity of the Neoparamoeba sp. isolate. Five other genera of amoebae, comprising Platyamoeba, Mayorella, Vexillifera, Flabellula, and Nolandella, a scuticociliate of the genus Paranophrys, and a trypanosomatid (tranosomatid-bodonid incertae sedis) accompanied Neoparamoeba sp. in the gills.

“…Traditionally, the taxonomy of kinetoplastids has been based on morphological characters and lifecycles, with the group being subdivided into two suborders: Bodonina and Trypanosomatina (Vickerman, 1976;Lom, 1976). See Maslov et al (2001) for an overview of this topic. Briefly, suborder Bodonina included two families: Bodonidae and Cryptobiidae.…”

Summary :To fully understand the evolutionary history of parasitic kinetoplastids and to understand the context within which the evolution of each parasite group has developed, an understanding not just of the parasites, but of all kinetoplastids is required. Accordingly, this paper provides an overview of kinetoplastid evolution and systematics, including coverage of the proposal by Moreira et al. (2004) to divide kinetoplasts into Prokinetoplastina (Ichthyobodo and Perkinsiella) and Metakinetoplastina (other bodonids and trypanosomatids). The implications of such a revision, with regard to correctly identifying outgroup taxa for studies of evolution within taxa of medical importance, are addressed, together with a more detailed review of the evolution and origins of the trypanosomes in the light of new phylogenies, new approaches and revisions in kinetoplastid systematics.KEY WORDS : kinetoplastid, trypanosome, Trypanosomatidae, Bodonidae, Prokinetoplastina, Metakinetoplastina, evolution.* School of Biosciences, University of Exeter, Exeter EX4 4PS, UK. E-mail: j.r.stevens@ex.ac.uk 2000) and even in those parasites of medical importance, it is little more than a decade since the widespread introduction of DNA sequencing technologies has allowed the evolution of parasitic trypanosomatids (and kinetoplastids in general) to be evaluated by formal phylogenetic analysis (Fernandes et al., 1993;Alvarez et al., 1996;Maslov et al., 1996;Lukes et al., 1997;Haag et al., 1998;Hannaert et al., 1998;Stevens et al., 1999Stevens et al., , 2001Wright et al., 1999;Hamilton et al., 2004;Moreira et al., 2004). To fully understand the evolutionary history of parasitic kinetoplastids and to understand the context within which the evolution of each parasite group has unfolded, an understanding not just of the parasites, but also of broader kinetoplastid phylogenetics is required. Accordingly, this paper provides an overview of kinetoplastid phylogenetics and evolution, together with a more detailed review of the evolution of the trypanosomes in the light of recent revisions in kinetoplastid systematics. For more comprehensive details of these topics, in addition to the references given above, readers are referred to reviews by Maslov et al. (2001), Stevens et al. (2001) and, most recently, Simpson et al. (2006). KINTEOPLASTID PHYLOGENETICST he order Kinetoplastida comprises a group of protozoa defined by the presence of a characteristic organelle, the kinetoplast (Vickerman, 1976), a large modified mitochondrion. Traditionally, the taxonomy of kinetoplastids has been based on morphological characters and lifecycles, with the group being subdivided into two suborders: Bodonina and Trypanosomatina (Vickerman, 1976; Lom, 1976 (Castellani, 1903;Bruce & Nabarro, 1903;Lyons, 1992), haemoflagellate parasites of humans and domestic animals, including trypanosomes and Leishmania spp. are among some of the most wellstudied agents of parasitic diseases known today. In consequence, some of these organisms have long been the subject of invest...

“…Kinetoplastids are distinguished by a single mitochondrion near the basal body of the flagellus, with species that parasitized plants and animals, but includes free-living taxa of the family Bodonidae (Maslov et al 2001). The evolution of parasitism in trypanosomatids involves monogenetic and digenetic cycles.…”
