Parabasalids: Trichomonas vaginalis STI in humans?
most common parasitic infection in developed countries.
can Parabasalids:trichonmonas vaginalis from cyst?
No they can’t they don’t survive well outside the host (adapted to sexual transmission)
what are Euglenozoans?
unicellular
flagellated eukaryotes
