Babesiosis in humans is caused by infection with various species of Babesia (Apicomplexa, Piroplasmida), mainly transmitted by an arthropod vector--Ixodes spp. ticks. This review will focus on blood transfusion as another mode of Babesia transmission, especially in endemic areas, as well as the impact of human babesiosis on transfusion medicine.

Malaria and related apicomplexan parasites have two highly conserved organellar genomes: one is of plastid (pl) origin, and the other is mitochondrial (mt). The organization of both organellar DNA molecules from the human malaria parasite Plasmodium falciparum has been determined, and they have been shown to be tightly packed with genes. The 35-kb circular DNA is the smallest known vestigial pl...

Rhoptries are specialized secretory organelles found in the Apicomplexa phylum, playing a central role establishment of parasitism. The rhoptry content includes membranous as well proteinaceous materials that discharged into host cell regulated fashion during parasite entry. A set neck proteins form RON complex critically participates moving junction formation invasion. Some bulb associated wit...

Enolase genes from land plants and apicomplexa (intracellular parasites, including the malarial parasite, Plasmodium) share two short insertions. This observation has led to the suggestion that the apicomplexan enolase is the product of a lateral transfer event involving the algal endosymbiont from which the apicomplexan plastid is derived. We have examined enolases from a wide variety of algae...

BACKGROUND The coral is predominantly composed of the metabolically dependent coral host and the photosynthetic dinoflagellate Symbiodinium sp. The system as a whole interacts with symbiotic eukaryotes, bacteria and viruses. Gemmocystiscylindrus (cf. "type-N" symbiont) belonging to the obligatory parasitic phylum Apicomplexa (Alveolata) is ubiquitous in the Caribbean coral, but its presence in ...

Fecal samples from 3 species of Onychomys (Rodentia: Muridae) captured in New Mexico and Arizona were examined for coccidia. Six of the 59 (10%) were infected with a new species of Eimeria. Sporulated oocysts (n = 105) of this new species are subspheroidal, 17.4 x 16.1 (14-21 x 13-19) microm, with ellipsoidal sporocysts 10.4 x 5.7 (9-12 x 5-8) microm. This species occurred in 3 of 24 (13%) Onyc...

Caryospora matatu n. sp. is the first species of coccidia reported from the a horned bush viper, Atheris ceratophorus endemic to Tanzania. Oocysts are spherical or slightly subspherical, 19.8 (16-23) microns, a micropyle and an oocyst residuum are absent, a single polar granule is present. An oocyst wall is bilayered, approximately 1.5 microns thick, brownish and distinctly pitted. Sporocysts a...

The coccidian Caryospora bigenetica was first described in the snake Crotalus horridus (Viperidae) from United States of America. This study represents the first record of the occurrence of C. bigenetica in snakes in South America. Feces were sampled between November 2013 and May 2014 from 256 wild snakes maintained in scientific breeding facilities in the states of Mato Grosso do Sul (MS; n = ...
