Extrachromosomal DNA in the Apicomplexa. [PDF]

open access: yesMicrobiology and molecular biology reviews : MMBR, 1997
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.

Secondary Structure and X-ray Crystallographic Analysis of the Glideosome-Associated Connector (GAC) from Toxoplasma gondii

open access: yesCrystals, 2022
A model for parasitic motility has been proposed in which parasite filamentous actin (F-actin) is attached to surface adhesins by a large component of the glideosome, known as the glideosome-associated connector protein (GAC).

Identification and Validation of Toxoplasma gondii Mitoribosomal Large Subunit Components

open access: yesMicroorganisms, 2022
Mitochondrial ribosomes are fundamental to mitochondrial function, and thus survival, of nearly all eukaryotes. Despite their common ancestry, mitoribosomes have evolved divergent features in different eukaryotic lineages.

Circadian rhythms and circadian clock gene homologs of complex alga Chromera velia

open access: yesFrontiers in Plant Science, 2023
Most organisms on Earth are affected by periodic changes in their environment. The circadian clock is an endogenous device that synchronizes behavior, physiology, or biochemical processes to an approximately 24-hour cycle, allowing organisms to ...

Case report: Sarcocystis speeri, Aspergillus fumigatus, and novel Treponema sp. infections in an adult Atlantic spotted dolphin (Stenella frontalis)

open access: yesFrontiers in Veterinary Science, 2023
A complete postmortem examination, including a computed tomography scan “virtopsy” (virtual necropsy), gross necropsy, cytology, histology, and molecular diagnostics were performed to investigate the cause of death of a deceased adult male Atlantic ...

An Overview of Peripheral Blood Mononuclear Cells as a Model for Immunological Research of Toxoplasma gondii and Other Apicomplexan Parasites

open access: yesFrontiers in Cellular and Infection Microbiology, 2019
In biology, models are experimental systems meant to recreate aspects of diseases or human tissue with the goal of generating inferences and approximations that can contribute to the resolution of specific biological problems.

Toxoplasma gondii, endothelial cells and schizophrenia: is it just a barrier matter?

open access: yesFrontiers in Cellular and Infection Microbiology
Toxoplasma gondii is an obligatory intracellular parasite responsible for causing toxoplasmosis. It is estimated that approximately one-third of the world’s population has positive serology for toxoplasmosis. Acute T.

Investigação de anticorpos contra Sarcocystis neurona e Sarcocystis cruzi em equinos

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2015
Sarcocystis neurona is the primary agent for Equine Protozoal Myeloencephalitis (EPM), important neurological disease characterized by behavior or muscular changes, that impairs animal performance and husbandry. Sarcocystis cruzi is a pathogen related to
