Entering the host's bloodstream during the tick bite, the parasite infects RBCs, producing differentiated and undifferentiated trophozoites. (medscape.com)
Acanthamoeba2
Since access to propamidine isethionate (Brolene®) as a first-line treatment has been limited in recent years, in the current study, we examined the effects of pentamidine isethionate against trophozoite and cyst forms of Acanthamoeba . (ac.ir)
I am not sure I understand your question, but if you have been diagnosed with trophozoites of Plasmodium vivax in your blood, then you can be treated with normal anti-malarials (the World Health Organization recommends artemisinin-based combination therapies for first line treatment of uncomplicated malaria, but depending where you are, you might even just be able to take chloroquine), as these kill the blood stages of malaria. (malaria.com)
The causal agent exists in both active (trophozoite) and dormant (cyst) forms. (dovepress.com)
