| cryptic diversity of free-living parabasalids, pseudotrichomonas keilini and lacusteria cypriaca n. g., n. sp., as inferred from small subunit rdna sequences. | ultrastructural and molecular phylogenetic evidence indicate that the parabasalia consists of seven main subgroups: the trichomonadida, honigbergiellida, hypotrichomonadida, tritrichomonadida, cristamonadida, spirotrichonymphida, and trichonymphida. only five species of free-living parabasalids are known: monotrichomonas carabina, ditrichomonas honigbergii, honigbergiella sp., tetratrichomonas undula, and pseudotrichomonas keilini. phylogenetic analyses show that free-living species do not form ... | 2010 | 20880033 |
