of raptors: a review and update.
Peirce, "The significance of avian hematozoa
in conservation strategies," in Diseases and Treatened Birds, J.
Notably, phylogenetic comparison of 479 bp of the mitochondrial cytochrome b gene derived from protozoan cyst-like structures with known sequences of avian hematozoa
found 99%-100% homology of parasites from both outbreaks with the avian malaria parasites (Haemoproteus spp.) of European songbirds (Figure).
Distribution of the avian hematozoa
of North America.
Specific studies aimed at determining the pathogenicity of neotropical strains of avian hematozoa
are therefore desirable, as would be studies on vectors of these parasites.
The positive relationship between WBC levels and the intensity of haemoproteid infection recalls hematological changes that accompany infection with other avian hematozoa
, such as Leucocytozoon spp.
Hemograms and hematozoa
of sharp-shinned (Accipiter striatus) and Cooper's hawks (Accipiter cooperii) captured during spring migration in northern New York.
of water-fowl from the Kellogg Biological Station area in southwestern Michigan.
Malaria diagnosis was based on the identification of hematozoa
on a thin blood film and/or on a thick blood film stained with Giemsa.
None of the toads of either species harbored trematodes, hematozoa
in the blood, or coccidian oocysts in the feces.
were found in the 52 blood smears examined from male sharp-tailed grouse.
This finding confirmed the scarcity of hematozoa
in polar regions and provided baseline data for the little auk.
