Anemia in Ducks Infected with Leucocytozoon simondi*†
The Journal of Protozoology, 1966SYNOPSIS. Thirty‐four white Pekin ducklings were used to study the anemia associated with infection by Leucocytozoon simondi.The first appearance of gametocytes in the peripheral blood, as detected by thin smears, marked the onset of anemia. This anemia lasted for the duration of the initial parasitemia, usually reaching a low point early in the ...

Morphological study of microgametogenesis of Leucocytozoon simondi
Journal of Ultrastructure Research, 1970The fine structure of the microgametocytes and microgametogenesis of Leucocytozoon simondi , a parasite of ducks and geese, was studied and compared to those of the related genus Plasmodia . The morphology of the microgametocyte of L. simondi is identical to that of avian malarial parasites.

ON THE SPECIFICITY OF LEUCOCYTOZOON
Canadian Journal of Zoology, 1954Leucocytozoon simondi Mathis and Leger was transmitted artificially to a gosling. Other goslings became infected naturally when exposed beside infected ducks.

Leucocytozoon is the least studied genus of blood parasites of the order Haemosporida comparison with the genera Plasmodium and Haemoproteus. Its transmission is almost exclusively linked with a vector of the genus Simulium, which ensures the circulation of parasites in populations of wild and domestic birds. Numerous species have been are described by

Leucocytozoon spp. in some Hertfordshire Birds
Nature, 1958DURING the course of some work on the blood parasites of birds1 (some of which has been or will shortly be published2) gametocytes of several species of Leucocytozoon were observed in the blood of seven species of birds. In the absence of reports of the incidence of this parasite in British birds since those of Seligman and Sambon3 (in grouse ...
