An investigation of the hypothesis that Haemoproteus is not transmitted in the Delta Marsh area with related notes on leucocytozoon
… was collected supporting 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 …

Studies of the haematozoa of some birds of Northern California
… 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.

THE ABUNDANCE AND INFECTION STATUS OF ANOPHELES spp. MOSQUITOES AT THREE SITES IN LOUDOUN COUNTY, NORTHERN VIRGINIA
… in 2010 tested negative for avian Plasmodium and Haemoproteus parasites. However, in 2009, 20 (28%) pools out of 71 tested positive for avian Plasmodium and Haemoproteus parasites. Four (20%) pools tested positive for avian Plasmodium, three of which were composed of Anopheles quadrimaculatus and …

Prevalence and drivers of blood parasitism in African penguins (Spheniscus demersus)
… of known haemoparasite species of Plasmodium, Haemoproteus and Babesia across 12 breeding colonies. Babesia infection was confirmed for 60% of wild birds sampled, but methods used did not indicate infection with either Haemoproteus or Plasmodium species. Generalised linear modelling of …

Hematoza of Wood Ducks (Aix Sponsa) in Missouri
… (9.97%) harbored one or more blood parasites. Haemoproteus nettionis was the most common 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 …

Street-wise : does prey abundance buffer black sparrowhawks (Accipiter melanoleucus) from the negative health impacts of urbanisation?
… parasite infection (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 …

Emerging Infectious Disease: Host and Parasite Perspectives
… of parasites in the genera Plasmodium and Haemoproteus. I show that parasites in the genus Plasmodium exhibit low specificity and are therefore most likely to emerge in new hosts in the future. Subsequently, I characterized the global distribution of the single lineage of P. relictum that …

MHC Class I diversity influences haematozoon infection intensity in the polymorphic black sparrowhawk (Accipiter melanoleucus)
… individual estimates of 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 …

Coping with Chronic Infection: The Role of Glucocorticoid Hormones in Mediating Resistance and Tolerance to Parasites
… including malaria (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 …

DISTRIBUTION AND MOLECULAR ANALYSIS OF AVIAN MALARIA VECTORS ON FOUR CENTRAL VIRGINIA PROTHONOTARY WARBLER (PROTONOTARIA CITREA) BREEDING SITES
Avian malaria is a devastating disease that has decimated numerous bird species. This study sought to identify the vectors of avian malaria at four central Virginia Prothonotary warbler breeding sites. Twenty one thousand mosquitoes were collected and Culex salinarius, Cx. erraticus, and Cx. …

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 …
