Prospects for elucidating the phylogeny of the apicomplexa

Diseases caused by Apicomplexa include: The name of the taxon Apicomplexa derives from two Latin words — apex (top) and complexus (infolds) — and refers to a set of organelles in the sporozoite.The Apicomplexa comprise the bulk of what used to be called the Sporozoa, a group of parasitic protozoans, in general without flagella, cilia, or pseudopods.

Furthermore, the taxonomic framework for the Apicomplexa is rather tenuous in many respects.

A total of 13 haemogregarine haplotypes were identified, which fell into four main clades in a phylogenetic framework.

Phylogenetic analysis of six new lankesterellid haplotypes revealed that these parasites were distinct from, but phylogenetically related to, known Lankesterella species and might represent new taxa.

In this study, we assessed the diversity, distribution, host-specificity and infection patterns of apicomplexan parasites in amphibians and reptiles from Oman, Arabia.

Using a quantitative PCR approach we detected three apicomplexan parasites (haemogregarines, lankesterellids and sarcocystids).

This rapid, perpetual cycle of replication (merogony) and associated erythrocyte invasion and destruction usually lead to intravascular haemolysis, anaemia, haemoglobinuria and/or jaundice.

The severity of disease usually relates to host and parasite factors, but often the virulence/pathogenicity is of considerable importance.The organelle is an adaptation that the apicomplexan applies in penetration of a host cell. All species are obligate endoparasites of animals, Motile structures such as flagella or pseudopods are present only in certain gamete stages.The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.To restore access and understand how to better interact with our site to avoid this in the future, please have your system administrator contact [email protected] transmitted to their mammalian hosts by particular ixodid tick species.
