Five species of Leucocytozoon were recovered from 35/828 birds of 95 species examined from 6 sites in West Africa between May 1995 and June 2001. Leucocytozoon pogoniuli n. sp. is described from the tinker barbets Pogoniulus subsulphureus and Pogoniulus atroflavus. Leucocytozoon trachyphoni n. sp. is described from the barbet Trachyphonus purpureus. No leucocytozoids have been reported previous...

Species of Leucocytozoon (Haemosporida, Leucocytozoidae) traditionally have been described based on morphological characters of their blood stages and host cells, with limited information on their avian host specificity. Based on the current taxonomy, Leucocytozoon toddi is the sole valid species of leucocytozoids parasitizing falconiform birds. Using a nested polymerase chain reaction protocol...

BACKGROUND Leucocytozoonosis is a disease of birds caused by obligate intracellular protozoa of the genus Leucocytozoon. We determined the prevalence of Leucocytozoon spp. using light and transmission electron microscopy in domestic birds in southwest of Iran. METHODS A total of 825 blood smears from 275 birds were examined for presence of infection. The structure morphology of Leucocytozoon ...

The current taxonomy of leucocytozoids (Haemosporida, Leucocytozoidae) is based on the morphology of blood stages of the parasites and on limited information about their specificity. Recent molecular studies have revealed a remarkable genetic diversity of leucocytozoids, indicating that their taxonomic diversity may be greater than in the current classifications. We addressed this issue using m...

Birds of the order Anseriformes, commonly referred to as waterfowl, are frequently infected by Haemosporidia of the genera Haemoproteus, Plasmodium, and Leucocytozoon via dipteran vectors. We analyzed nucleotide sequences of the Cytochrome b (Cytb) gene from parasites of these genera detected in six species of ducks from Alaska and California, USA to characterize the genetic diversity of Haemos...

*Corresponding Author’s Email : [email protected] Tel.: +8801917379549 Presence of Leucocytozoonosis in pigeon and chicken and the pathology it produced were investigated in four (4) selected districts of Bangladesh (Khagrachari, Bandarban, Sylhet and Sunamgonj) during the period of January to December’ 2011. A total of 200 samples (live birds) were collected randomly. Both ante-mortem an...

Four species of Leucocytozoon, L. caprimulgi of the Caprimulgidae (nightjars), L. marchouxi of the Columbidae (pigeons and doves), L. grusi of the Gruidae (cranes) and L. tawaki of the Spheniscidae (penguins) are re-described. Leucocytozoon turtur is declared a synonym of L. marchouxi.

Leucocytozoon parasites infect many species of avian hosts, including domestic chicken, and can inflict heavy economic loss on the poultry industry. Two major species of Leucocytozoon parasites have been reported in China, L. sabrazesi and L. caulleryi, although L. sabrazesi appears to be more widespread than L. caulleryi in southern China. The traditional method for detecting Leucocytozoon inf...
