High voltage electron microscopy on microgametogenesis of Haemoproteus columbae
Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1974The microgametogenesis of Haemoproteus columbae was investigated by high voltage and conventional electron microscopy and the results were compared. The features of microgametogenesis which have become clear by high voltage electron microscopy include the distribution and arrangement of axonemes in the microgametocyte and the budding process and ...

Ultrastructure of the Ookinetes of Haemoproteus meleagridis (Haemosporina: Haemoproteidae)
The Journal of Parasitology, 1989Ookinetes of Haemoproteus meleagridis were structurally similar to kinetes of other apicomplexan parasites and possessed a polar ring complex (PRC) composed of an electron-lucent polar ring with 25 supporting tines. Fifty subpellicular microtubules were anchored in a circle to the inner surface of the polar ring.

The Fine Structure of Haemoproteus columbae Sporozoites*
The Journal of Protozoology, 1972SYNOPSIS. The fine structure of Haemoproteus columbae sporozoites has been studied and compared to sporozoite structure as revealed by the light microscope. The sporozoites are ultrastructurally similar to those of other Haemosporidia in that they possess a 3‐layered pellicle, subpellicular microtubules, polar ring, micropore, free ribosome‐like ...

A New Vector of Haemoproteus colmubae in England
The Journal of Protozoology, 1957SUMMARY. Haemoproteus columbae of English wood pigeons (Columba palumbus palumbus L.) was found to undergo sporogony in Ornithomyia avicularia. It is suggested that this insect is a vector of H. columbae, in spite of the failure of six attempts to transmit the haemosporidian to uninfected domestic pigeons (C. livia var.

Ultrastructural Study of Gametocytes and Gametogenesis of Haemoproteus metchnikovi
The Journal of Protozoology, 1972SYNOPSIS. The ultrastructure of gametocytes and microgametogenesis of Haemoproteus metchnikovi, an intracellular malaria parasite of chelonians, was compared with other malarial parasites. Gametocytes resemble those described for other avian, reptilian and mammalian malarial parasites.
