Plasmodium inui shortti was studied in monkeys (66 Macaca mulatta, 2 M. fascicularis, 12 Saimiri boliviensis, 4 Aotus lemurinus griseimembra, and 1 A. nancymaae). Prepatent periods for 30 sporozoite transmissions by Anopheles stephensi, An. dirus, and An. maculatus mosquitoes ranged from 10 to 48 days with a median of 15.5 days. In rhesus monkeys, mean maximum parasite counts for intact animals were 181,970/muL; for splenectomized animals, the mean maximum parasite count was 1,167,890/muL.

Article Synopsis
- * A study analyzed 80 complete coding sequences of ama1 from P. inui in macaques in Thailand, identifying 74 nucleotide substitutions and 60 haplotypes across two phylogenetic lineages, hinting at selective pressures.
- * Notably, a significant number of amino acid substitutions were tied to immune response, with some showing alterations that could be harmful, indicating ongoing evolution and potential challenges for vaccine strategies.

Zoonotic malaria, caused by Plasmodium knowlesi, Plasmodium cynomolgi, Plasmodium coatneyi, and Plasmodium inui, is a significant global health concern. The gold standard microscopy, while widely used for malaria diagnosis, faces limitations in differentiating between malaria species. Polymerase chain reaction (PCR), despite its accuracy, is characterized by high costs and time-consuming procedures.

Malaria continues to be a global public health problem although it has been eliminated from many countries. Sri Lanka and China are two countries that recently achieved malaria elimination status, and many countries in Southeast Asia are currently in the pipeline for achieving the same goal by 2030. However, Plasmodium knowlesi, a non-human primate malaria parasite continues to pose a threat to public health in this region, infecting many humans in all countries in Southeast Asia except for Timor-Leste.

Malaria is a parasitic disease caused by protozoan species of the genus and transmitted by female mosquitos of the genus and other Culicidae. Most of the parasites of the genus are highly species specific with more than 200 species described affecting different species of mammals, birds, and reptiles. species strictly affecting humans are , , , and More recently, and other nonhuman primate plasmodia were found to naturally infect humans.
