We report here the enzymatic biosynthesis of FR-900098 analogues and establish an in vivo platform for the biosynthesis of an N-propionyl derivative FR-900098P. FR-900098P is found to be a significantly more potent inhibitor of Plasmodium falciparum 1-deoxy-D-xylulose 5-phosphate reductoisomerase (PfDxr) than the parent compound, and thus a more promising antimalarial drug candidate.

Background: The Highlands of Papua New Guinea are non-endemic for malaria compared to the rest of the country. This study aimed to explore the local transmission of malaria in the Highlands through a cross-sectional school survey coupled with reactive case detection.
Methods: Between July and November 2019, 5575 schoolchildren and 1048 household members were screened for malaria using Rapid Diagnostic Tests, subsequently validated by light microscopy.

Parasitic infections can profoundly impact brain function through inflammation within the central nervous system (CNS). Once viewed as an immune-privileged site, the CNS is now recognized as vulnerable to immune disruptions from both local and systemic infections. Recent studies reveal that certain parasites, such as Toxoplasma gondii and Plasmodium falciparum, can invade the CNS or influence it indirectly by triggering neuroinflammation.

Plasmodium falciparum is a major cause of severe malaria. This protozoan infects human red blood cells and secretes large quantities of histidine-rich protein 2 (PfHRP2) into the bloodstream, making it a well-known diagnostic marker. Here, however, we identified PfHRP2 as a pathogenic factor produced by P.

SURFINs protein family expressed on surface of both infected red blood cell and merozoite surface making them as interesting vaccine candidate for erythrocytic stage of malaria infection. In this study, we analyze genetic variation of Pfsurf4.1 gene, copy number variation, and frequency of SURFIN4.

We report two cases of recurrent malaria in U.S. travelers returning from Africa (Ghana and Central African Republic) despite a full course of artemether-lumefantrine (AL).
