The fine structure of a macrogametocyte of Fallisia copemani, a parasite found in the circulatory blood lymphocytes of the Australian skink Carila rhomboidalis, is described. The macrogametocyte is bounded by two membranes, a thick outer one and a fine inner one. Beneath these membranes, ribosomes aggregate into two concentric layers, a character unique among Haemosporidia. The cytoplasm contains a nucleus, numerous ribosomes, tubular mitochondria, osmiophilic bodies, spherical bodies and a cluster of vesicles.
Résumé
L’ultrastructure d’un macrogamétocyte de Fallisia copemani, parasite du scinque australien Carila rhomboidalis est décrit dans un lymphocyte circulant. Le macrogamétocyte est limité par deux membranes, une membrane externe épaisse et une membrane interne fine. Sous ces membranes, la disposition de ribosomes en deux couches concentriques est un caractère nouveau et unique parmi les Hémosporidies. Le cytoplasme renferme un noyau, de nombreux ribosomes, des mitochondries tubulaires, des corps osmiophiles, des corps sphériques et des amas de vésicules.
