title: [Ultrastructural observations on the blood stages of Garniidae (G. gonatodi G. uranoscodoni and Fallisia effusa) parasites of South American Lizards)].
abstract: The ultrastructural study of two species of Garnia (G. gonatodi and G. uranoscodoni) and of Fallisia effusa demonstrates that the Garniidae possess the fundamental structures of Haemosporidia. A vacuolar digestive system was not found and the absence of pigment granules is confirmed. A number of caracteristics (- centriolar plaque inside a nuclear pore; - highly developed cytosqueleton in the host cell of F. effusa; - advanced maturation stages of gamétocytes of F. effusa in the vertebrate host) allow comparisons between the Garniidae and Plasmodiidae, Leucocytozoidae and Haemoproteidae. The authors' conclusion is that Garnia and Fallisia, although clearly different from each other, have common ultrastructural characteristics which also separate them from the other Haemosporidian families.
