There Is Treasure Everywhere: Reductive Plastid Evolution in Apicomplexa in Light of Their Close Relatives

open access: yesBiomolecules, 2019
The phylum Apicomplexa (Alveolates) comprises a group of host-associated protists, predominately intracellular parasites, including devastating parasites like Plasmodium falciparum, the causative agent of malaria.

Myosin Diversity in Apicomplexa

Journal of Parasitology, 2001
A polymerase chain reaction (PCR) screen was used to examine the diversity of myosins in 7 Apicomplexan parasites: Toxoplasma gondii, Plasmodium falciparum, Neospora caninum, Eimeria tenella, Sarcocystis muris, Babesia bovis, and Cryptosporidium parvum.

Examination of Secondary Metabolite Biosynthesis in Apicomplexa

ChemBioChem, 2023
AbstractNatural product discovery has traditionally relied on the isolation of small molecules from producing species, but genome‐sequencing technology and advances in molecular biology techniques have expanded efforts to a wider array of organisms. Protists represent an underexplored kingdom for specialized metabolite searches despite bioinformatic ...

Hijacking of Host Cellular Functions by the Apicomplexa

Annual Review of Microbiology, 2008
Intracellular pathogens such as viruses and bacteria subvert all the major cellular functions of their hosts. Targeted host processes include protein synthesis, membrane trafficking, modulation of gene expression, antigen presentation, and apoptosis.

Intestinal Apicomplexa

1999
Abstract A large number of organisms previously placed in different zoologic groups were found to have a set of organelles seen in electron micrographs and called the apical complex. The apical complex is located in the anterior part of the body and is present in one or more stages of the life cycle of these parasites.

The Genus Atoxoplasma (Protozoa, Apicomplexa)

The Journal of Parasitology, 1982
The apicomplexan protozoan genus Atoxoplasma Garnham, 1950 is resurrected and the family Atoxoplasmatidae n. fam. established for homoxenous blood parasites of birds that develop asexually in both the blood and intestinal cells, and form oocysts that are passed unsporulated in the feces, sporulate on the ground, and then infect new hosts.

Apicomplexa Of The Blood

1999
Abstract The Apicomplexa of blood belong to the class Haematozoea, which has two orders: Haemosporida and Piroplasmida. Haemosporida has the family Plasmodiidae, with the genus Plasmodium. Piroplasmida has the family Babesiidae, with the genera Babesia and Entopolypoides ( Corliss, 1994).

Sexual differentiation and sex determination in the Apicomplexa

Trends in Parasitology, 2002
Protozoan parasites of the phylum Apicomplexa have complex life cycles involving various types of asexual division that allow rapid proliferation of parasites within one or more hosts. Such replication is punctuated by obligate sexual differentiation that produces male and female gametocytes.

Tissue Apicomplexa

1999
Abstract Members of the Apicomplexa in human tissues other than the intestine and blood belong to the genera Sa cocystis and Toxoplasma of the family Sarcocystidae, characterized, as already stated, by two hosts in their life cycles. The Sarcocystis organisms occurring in the intestine of humans were studied in Chapter 8.

Endocytic Activity by Apicomplexa Parasites

Acta Parasitologica
Macromolecules are incorporated by eukaryotic cells through a process known as endocytosis, intensely analyzed in mammalian and yeast cells, but still lacking deep studies in pathogenic protists. Here we present what is presently known on endocytic activity carried out in some members of the Apicomplexa group (mainly concentrated in Plasmodium and ...
