Gametocytogenesis of Leucocytozoon Smithi

Journal of Eukaryotic Microbiology, 1993
ABSTRACT. Development of young gamelocytes of Leucocytozoon smithi into morphologically mature forms was studied using electron microscopy. Gametocytogenesis began on day seven post inoculation when merozoites, released from ruptured hepatic schizonts, developed into gametocytes within mononuclear phagocytes or leukocytes (monocytes or lymphocytes).

On Species of Leucocytozoon

1974
Publisher Summary This chapter describes Leucocytozoon. It discusses the prevalence, taxonomy, life cycles, ultrastructure, pathogenesis, and pathology of these avian blood parasites, together with treatment in terms of prevention and control, immunity and cultivation.

Early Schizonts of Leucocytozoon caulleryi

The Journal of Parasitology, 1990
Sporozoites of Leucocytozoon caulleryi were inoculated intravenously into 26-day-old specific pathogen-free chickens. Six days after inoculation, early schizonts were detected in lung, spleen, and thymus. They existed separately and were spherical or ovoid, 30-35 microns in diameter, and had well defined walls.

ARE LEUCOCYTOZOON SAKHAROFFI SAMBON AND LEUCOCYTOZOON BERESTNEFFI SAMBON SYNONYMOUS?

Canadian Journal of Research, 1950
The size of the gametocytes of a leucocytozoon in young crows shows a wide variation in birds obtained in different localities. The host cell nucleus of infected cells may be pushed to one side, almost surround the parasite, or be intermediate between these extremes.

Leucocytozoon (Haemosporida; Leucocytozoidae) of the Falconiformes

Canadian Journal of Zoology, 1977
Falconiform-inhabiting species of Leucocytozoon are reviewed and a checklist of Falconiformes known to harbor Leucocytozoon is included. Morphological measurements were made from 11 falconiform species to examine the interspecific and intraspecific variations. These formed the basis for the redescription of gametocytes of L. toddi Sambon.

Sporogonic Development of Leucocytozoon smithi

The Journal of Protozoology, 1992
The sporogonic development of Leucocytozoon smithi in its black fly vector was studied by light and electron microscopy and was compared with that of other haemosporidians. Within 18 to 24 h after ingestion of gametocytes by black flies, ookinetes passing through the midgut epithelium were observed.

Leucocytozoon Disease of Turkeys

World's Poultry Science Journal, 1977
Leucocytozoon disease of turkeys, like that of other avian species, is caused by a blood protozoan that has a complex life cycle involving development in the bird (asexual) and in an intermediate h...

Crystalline inclusions in Leucocytozoon simondi

Canadian Journal of Zoology, 1971
Vacuoles have been observed in haemosporidian ookinetes fixed in methanol and stained with Giemsa's (5) (Fig. 1). Electron microscopy studies on sporogony of Leucocytozoon simondi indicate that the "vacuoles" contain accumulations of crystalline material (8) (Fig. 3).

Leucocytozoon spp : Leucocytozoonosis

2023
La leucocytozoonosis es una parasitosis de las aves producida por especies de Haemosporida (Apicomplexa) pertenecientes a la familia Leucocytozoidae, de ciclo indirecto y de distribución mundial, transmitida por vectores dípteros hematófagos. Algunas especies han sido asociadas a brotes de enfermedad, e incluso muertes en aviarios, zoológicos y granjas

Schizogonic Development of Leucocytozoon smithi

The Journal of Protozoology, 1992
ABSTRACT The schizogonic development of Leucocytozoon smithi in the liver of experimentally infected turkey poults was examined by electron microscopy. Following intraperitoneal injection, sporozoites migrated to the liver and entered hepatic cells to become intracellular trophozoites.
