An investigation of the hypothesis that Haemoproteus is not transmitted in the Delta Marsh area with related notes on leucocytozoon
… the concept that, while Haemoproteus and Leucocytozoon are present as parasites of ducks in the Delta Marsh area, transmission does not occur locally. This was substantiated by two facts - firstly the absence of suitable insect vectors and secondly the lack of transmission to experimental …

Studies of the haematozoa of some birds of Northern California
… for hemoprotozoa of the genera Haemoproteus, Leucocytozoon, and Trypanosoma, and (2) to construct an up-to-date check-list of the Haemoproteus, Leucocytozoon, and Trypanosoma parasites of birds of North America.

Friends or foes? Blood parasite costs and defence abilities in young raptor hosts
… nestlings infected with the blood parasite Leucocytozoon toddi display low transcriptional response to increasing parasitemia (density of parasite per host cells), moderate signs of parasite-induced tissue damages in the blood, disease symptoms only at the highest parasitemia level, and …

Patterns of avian haemosporidia in birds within the greater Cape Town area
… genera Haemoproteus, Plasmodium, Fallisia and Leucocytozoon.

The Incidence and Intensity of Haematozoa in the Common Crow (Corvus brachyrhynchos) of Western Washington
… on the protozoan genera Haemoproteus, Leucocytozoon, Plasmodium and Trypanosoma with observations on the nematode group microfilaria, are based entirely on materials collected at Auburn, Washington during the spring of 1970.</p> <p>Despite the numerous studies on prevalence of blood …

Hematoza of Wood Ducks (Aix Sponsa) in Missouri
… parasite, occurring in 36 (9.70%) of the birds. Leucocytozoon simondi was found in 2 (0.54%) and microfilaria occurred in 5 (1.35%) of the wood ducks that were examined. Prevalence data indicated that infections were higher in adults than in immature birds. There was no difference in prevalence …

An investigative study on the effects of black fly (diptera: simuliidae) sugar meals on reproductive success and parasite transmission /
… did not have a greater vectoring potential of Leucocytozoon simondi when maintained on artificial honeydew as opposed to artificial nectar when fed ad libitum. However, all flies maintained on the two sugars (artificial honeydew and artificial nectar) survived longer, produce more eggs and had …

Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
… flies, but they influenced the resistance of Leucocytozoon-infected flies to the parasite. Amino acid-containing diets appeared to extend the survival of mosquitoes, and also allowed them to take more vertebrate blood when they blood fed.

Street-wise : does prey abundance buffer black sparrowhawks (Accipiter melanoleucus) from the negative health impacts of urbanisation?
… (presence and abundance of Haemoproteus and Leucocytozoon). Trends in diet composition along a gradient of urban cover were determined through the analysis of prey remains collected in the immediate nest surroundings and differences in prey abundance were determined through point counts in …

MHC Class I diversity influences haematozoon infection intensity in the polymorphic black sparrowhawk (Accipiter melanoleucus)
… blood parasite load (for Haemoproteus nisi and Leucocytozoon toddi); the study tested the relationship between (i) allelic diversity and individual parasite load and (ii) specific alleles and individual parasite load using a Generalized Linear Model framework. Seven different, putatively …

Coping with Chronic Infection: The Role of Glucocorticoid Hormones in Mediating Resistance and Tolerance to Parasites
… (Plasmodium) and malaria-like (Haemoproteus and Leucocytozoon) parasites. I performed a medication experiment (Chapter II) to identify the physiological consequences of Haemosporidian infection and explored the relationships between glucocorticoids and parasite resistance and tolerance in both an …

IMPACTS OF BLOODBORNE PATHOGEN INFECTIONS ON BREEDING ECOLOGY AND SUCCESS IN WHITE-THROATED SPARROWS (Zonotrichia albicollis)
<p>Bloodborne pathogens have significant and persistent impacts on avian populations worldwide, including decreased long-term survival and population size. Existing research indicates that chronic pathogen infections may have negative impacts on nesting success, such as decreased numbers of …
