Blood films from 60 mallard (Anas platyrhynchos) and 67 pintail (A. acuta) ducks, collected in Alberta and the Mackenzie Delta, Northwest Territories, during 1973 and 1974, were examined for blood parasites. Twenty-two (37%) of the mallards and fourteen (21%) of the pintails were infected with one or more species of hematozoa. Infections of Leucocytozoon simondi occurred more frequently (86%) than Haemoproteus nettionis (22%) in the infected birds. Trypanosoma avium occurred in one individual… Expand
BLOOD PARASITEMIA IN A SOUTH TEXAS WINTERING WATERFOWL POPULATION 1
TLDR
Blood parasites were found in 85 of 580 ducks (14.6%) throughout the wintering period and adult blue-winged teal and lesser scaup were more heavily infected than juveniles. Expand

TLDR
Blood smears from 837 mallard ducks collected during January and February from various locales in Washington during the period 1974-1977 were examined for hematozoa, and leucocytozoon simondi was the most common, occurring in 24.4% of the birds. Expand
Detection, prevalence, and transmission of avian hematozoa in waterfowl at the Arctic/sub-Arctic interface: co-infections, viral interactions, and sources of variation
TLDR
Prevalence estimates for Haemoproteus, Leucocytozoon, and Plasmodium infections in waterfowl at the interface of the sub-Arctic and Arctic and provide evidence for local transmission of all three parasite genera are presented. Expand
Evaluation of blood and muscle tissues for molecular detection and characterization of hematozoa infections in northern pintails (Anas acuta) wintering in California.
TLDR
Limited evidence for differences between tissue types in detection probability and prevalence of Leucocytozoon, Haemoproteus, and Plasmodium parasites is found, which supports the utility of both sample types for obtaining information on hematozoan infections. Expand
Haemoprotozoan infection in ducks: prevalence and pathology
TLDR
It may be concluded that haemoprotozoan infection in duck is highly prevalent in Bangladesh and produces clinicopathological lesions in duck so proper control measures should be taken to reduce the prevalence of haemobiology of duck in Bangladesh. Expand
Assessing the evidence for intercontinental redistribution of infectious agents by migratory birds
TLDR
Results of this study and recent parallel investigations suggest that genetic exchange of IAV may be extensive between North America and the northern Neotropics and new evidence supporting the role of migratory birds in redistributing viral and parasitic agents between continents is provided. Expand
QUANTIFICATION OF HEMATOZOA IN BLOOD SMEARS
TLDR
The number of erythrocytes that must be counted to determine parasite intensities could be considerably reduced from the 10,000 or 20,000 estimated for most studies, and still provide an accurate determination of the number of parasites/n ery throatcytes in datasets collected from hosts with moderate to high levels of parasitemia.

A LACK OF AVIAN AND MAMMALIAN HAEMATOZOA IN THE ANTARCTIC AND CANADIAN ARCTIC
TLDR
An absence of vectors precludes local transmission in the areas sampled, and while wide-ranging migratory birds nesting in the Arctic could be exposed to infection elsewhere, many of them are normally protected from this hazard by ecological barriers. Expand
