The link between humans and six parasitic genera. Plasmodium, Leishmania, and Trypanosoma are transferred to humans mainly through the bite of an infected vector, while Toxoplasma, Giardia, and Entamoeba are transmitted via ingestion.
Table I.
Plasmodium species treatment and possible resistance proteins summary
| Plasmodium |
|---|
| Uncomplicated malaria by CQS P. vivax, P. ovale, P. malariae, P. knowlesi, and P. falciparum |
| CQ phosphate; is also the drug of choice for pregnant women |
| Uncomplicated malaria by CQR P. falciparum, P. vivax, and P. ovale |
| An ACT combination such as ARM-LF; is also the drug of choice for pregnant women |
| Anti-relapse treatment P. vivax and P. ovale |
| PRQ phosphate or TFQ; Anti-relapse is risky during pregnancy |
| Complicated malaria regardless of the species or drug susceptibility |
| Administer intravenous ARN |
| Possible proteins involved in resistance |
| P. vivax: PvMDRI (CQ, ARN, and MQ), PvDFHR-TS, and PvDHPS (SP) |
