    Apicomplexans lack the ability to synthesize fatty acids de novo because it is different from human fatty acid synthesis. Plasmodium has an essential unique protein on its parasitovacuole membrane (PVM) called UIS3 (upregulated infective sporozoite

    suggests that it is a Na efflux pump, extruding Na in exchange for H. Here we demonstrate that ATP4 proteins belong to a clade of P-type ATPases that are restricted to apicomplexans and their closest relatives. We employed a variety of genetic... and physiological approaches to investigate the ATP4 protein of the apicomplexan Toxoplasma gondii, TgATP4. We show that TgATP4 is a plasma membrane protein. Knockdown of TgATP4 had no effect on resting pH or Ca2 but rendered parasites unable to regulate

    Investigation of Nematopsis spp. oocysts in 7 species of bivalves from Chonburi Province, Gulf of Thailand
    (2004-01-28) C. Tuntiwaranuruk; K. Chalermwat; E. S. Upatham; M. Kruatrachue; C. Azevedo; Burapha University; Mahidol University; Department of Cell Biology
    the prevalence of the apicomplexan parasite Nematopsis Schneider, 1892. Nematopsis spp. sporozoites were found in the cultivated bivalves Aicuatula arcuatula, Anadara granosa and Perna viridis as well as the locally harvested Paphia undulata. They were not found.... granosa, 17.61 ± 0.69/12.72 ± 0.36 μm (n = 50) for P. viridis, and 11.21 ± 0.62/8.55 ± 0.52 μm (n = 50) for P. undulata. Identification of oocysts of these apicomplexan gregarines to species was not attempted. The prevalence of infection in relation

Genetic variants were mapped onto existing three-dimensional structures. Genome-wide single nucleotide... in every Apicomplexan species. Haemoglobin-specific falcipains are separated from invasion-related falcipain, and their expansions within one specific locus arose independently in both P. falciparum and P. vivax lineages.

    Sideways: road to gene-by-gene functional screening in malaria parasites
    (2023-05-01) Chookajorn T.; Billker O.; Mahidol University
    Genome-wide screening in apicomplexan species has transformed our understanding of these parasitic protozoa. Kimmel et al. report a 'knock sideways' system and provide a powerful use case for its feasibility in a gene-by-gene screening in Plasmodium
