Protozoan parasites have developed elaborate motility systems that facilitate infection and
dissemination. For example, amoebae use actin-rich membrane extensions called …

Early electron microscopy studies revealed the elaborate cellular features that define the
unique adaptations of apicomplexan parasites. Among these were bulbous rhoptry (ROP) …

The phylum Apicomplexa comprises important eukaryotic parasites that invade host tissues
and cells using a unique mechanism of gliding motility. Gliding is powered by actomyosin …

Plasmodium species cause malaria by proliferating in human erythrocytes. Invasion of
immunologically privileged erythrocytes provides a relatively protective niche as well as …

Cyclic GMP (cGMP)-dependent protein kinase (protein kinase G [PKG]) is essential for
microneme secretion, motility, invasion, and egress in apicomplexan parasites, However …

The apical complex is the instrument of invasion used by apicomplexan parasites, and the
conoid is a conspicuous feature of this apparatus found throughout this phylum. The conoid …

Apicomplexa are obligatory intracellular parasites that sense and actively invade host cells.
Invasion is a conserved process that relies on the timely and spatially controlled exocytosis …

Members of Apicomplexa are defined by apical cytoskeletal structures and secretory
organelles, tailored for motility, invasion and egress. Gliding is powered by actomyosin …

Rhoptries are specialized secretory organelles found in the Apicomplexa phylum, playing a
central role in the establishment of parasitism. The rhoptry content includes membranous as …

Apicomplexans, including species of Eimeria, pose a real threat to the health and wellbeing
of animals and humans. Eimeria parasites do not infect humans but cause an important …
