Prevalence of hemoparasites has been investigated in many avian species throughout Europe and North America. Basic hematologic surveys are the first step toward evaluating whether host-parasite prevalences observed in North America and Europe occur elsewhere in the world. We collected blood smears from 94 nestling imperial eagles (Aquila heliaca), five nestling steppe eagles (Aquila nipalensis)...

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...

We tested the hypothesis that malarial parasites (Plasmodium and Haemoproteus) of black-throated blue warblers (Dendroica caerulescens) provide sufficient geographical signal to track population movements between the warbler's breeding and wintering habitats in North America. Our results from 1083 warblers sampled across the species' breeding range indicate that parasite lineages are geographic...

The common term, "malaria parasites," is controversial in its use. Malaria is a disease, not a parasite. Thus, it is not appropriate to write or speak of "malaria infecting a bird." So, the parasites should be referred to as "malaria parasites" just as we might refer to "the cold virus." But, malaria is a human disease, with characteristic symptoms. Infection causes pathology in other vertebrat...

Sporulated oocysts (mean dimensions = 13.0 x 10.8 tm) and sporocysts (11.3 x 5.5 Mm) of a coccidian resembling Frenkelia sp. or Sarcocystis sp. were present in the lamina propria of the small intestine of a naturallyinfected northern spotted owl (Strix occidentalis caurina) collected near Medford, Oregon (USA). Dimensions of these oocysts and sporocysts appear to be considerably smaller than th...

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 ...

Chewing lice (Phthiraptera: Ischnocera and Amblycera) are permanent, obligate, host-specific ectoparasites commonly found in birds. This study detects the types of chewing on living migratory 436 birds were detected Razzaza Lake that included captured during migration from October 2021 to February 2022 like Anas strepera, crecca, platyrhynchos, clypeata. The soaked 70% ethyl alcohol three speci...

The coccidians Frenkelia microti and F. glareoli (Apicomplexa: Sarcocystidae) form tissue cysts in the brain of small rodents (intermediate hosts) while oocysts are formed in the intestine of final hosts, buzzards of the genus Buteo. The inclusion of the small subunit ribosomal RNA gene sequences (SSU rRNA) of both Frenkelia species into the SSU rRNA trees of other, tissue cyst-forming coccidia...

A large number of studies have demonstrated that habitat characteristics have a huge impact on all aspects of animal life history. This hypothesis predicts a relationship between habitat structure and the main components of fitness and, consequently, also predicts a relationship between habitat structure and other traits indirectly related to fitness, such as condition or health. We tested whet...

Abstract Background Avian malaria parasites are microorganisms parasitizing erythrocytes and various tissues of the birds; they common distributed worldwide. These known to infect birds different taxa be cause deaths in wild captivity. The species with ability colonize new territories local non-migratory particular interest. This scenario is likely temperate zones Europe, because climate change...
