Leucocytozoon grallariae (also known as Undulated Antpitta) is a parasite, found in non-migratory highland passeriforms in the Grallariidae and Cotingidae that infects birds in the area.[1][2] Undulated Antpitta is also spread throughout in the Andean mountain ranges normally in humid forests and scrublands of Bolivia, Peru, Ecuador, Colombia and Venezuela.
They contain gametocytes within fusiform host cells. However, it's been determined that these parasites are present in co-infections with other species belonging to the species Leucocytozoon. In this parasite, gametocytes develop in circular shaped host cells which exhibits two highly distant parasite lineages isolated from the same samples.[3] Young gametocytes have an effect on the shape of host cells starting at primal stages of their development. Parasites that are growing have oval or ellipsoid shapes; these parasites stick to the host cell nuclei, which are enlarged, deformed and have a crescent shape. The host's cell cytoplasm near growing gametocytes. Advanced young gametocytes have invaginations lining their sides. This is opposite to the host cell nuclei, which gives the growing gametocytes the appearance of giant beans with rounded ends. Host cells take on the ellipsoid shape from the very early stages of gametocyte development.The rest of the life cycle follows the same as the rest of the Leucocytozoon species.
