High voltage electron microscopy on microgametogenesis of Haemoproteus columbae

Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1974
The 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, 1989
Ookinetes 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.

HAEMOPROTEUS AND LEUCOCYTOZOON INFECTIONS IN BIRDS OF THE OKLAHOMA CITY ZOO

Journal of Wildlife Diseases, 1983
A total of 222 birds, captive or free-flying in the Oklahoma City Zoo, were examined for blood parasites; 31 (14%) harbored Haemoproteus and/or Leucocytozoon. While 21% of the indigenous avifauna were infected, only 8% of the exotic bird species harbored haemoproteids and these parasites were also exotic to North America.

The Fine Structure of Haemoproteus columbae Sporozoites*

The Journal of Protozoology, 1972
SYNOPSIS. 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, 1957
SUMMARY. 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, 1972
SYNOPSIS. 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.
