The epidemiology of a novel Leucocytozoon parasite in an endangered population of marbled murrelets (Brachyramphus marmoratus) on the Oregon coast [PDF]

International Journal for Parasitology: Parasites and Wildlife
Parasitism is a known cause of morbidity and mortality in wildlife species and may exacerbate population declines in species threatened by changing landscapes.

Insights from common buzzard broods on the interaction between Leucocytozoon infection, watercourse habitats and simuliid blackfly vectors [PDF]

International Journal for Parasitology: Parasites and Wildlife
Blood parasites of the genus Leucocytozoon commonly infect many bird species worldwide and are particularly prevalent in birds of prey. As a vector-borne parasitic disease, the infection occurrence overlaps with that of the dominant vectors: blackflies ...

First microscopic, pathological, epidemiological, and molecular investigation of Leucocytozoon (Apicomplexa: Haemosporida) parasites in Egyptian pigeons [PDF]

Frontiers in Veterinary Science
IntroductionLeucocytozoon is an intracellular blood parasite that affects various bird species globally and is transmitted by blackfly vectors. This parasite is responsible for leucocytozoonosis, a disease that results in significant economic losses due ...

Use of Contaminated Habitat and Associated Selenium Uptake Mediate Haemosporidian Parasite Infections in Wild Passerine Birds. [PDF]

Ecol Evol
We conducted a community‐scale field study to evaluate whether trace element contaminants derived from coal combustion residuals and nuclear fission products alter the dynamics of haemosporidian blood parasites, dipteran vectors, and avian hosts in riparian and wetland habitats in South Carolina, USA.

Prevalence of Avian Haemosporidian Parasites: A Comparative Study between Resident and Migratory Birds of Iraq [PDF]

Iranian Journal of Animal Biosystematics, 2023
Haemosporidians are a diverse group of vector-borne parasitic protozoa that have a global distribution and some of them live in the avian body as a benign parasite, with no symptoms.

Prevalence and Genetic Diversity of Haemoproteus and Leucocytozoon in Raptors and Other Captive Birds at the National Zoological Garden in South Africa. [PDF]

Integr Zool
Captive birds at the National Zoological Garden in South Africa harbor diverse haemosporidian parasite species and lineages. This might compromise conservation efforts of threatened species. ABSTRACT Avian haemosporidian infections have been associated with disease outbreaks in zoos and rehabilitation centers globally. This study aimed to determine the

Blood Parasites and Wildlife: The Development of a Discipline. [PDF]

Integr Zool
Changes in our knowledge on blood parasite infections of wild animals in the last 30 years is reviewed with emphasis on taxonomy and phylogeny, impact of infections on fitness, and distribution of blood parasites. ABSTRACT In the last 30 years, the area of the study of parasitism caused by blood parasite infections on wildlife has suffered an ...

Leucocytozoon cariamae n. sp. and Haemoproteus pulcher coinfection in Cariama cristata (Aves: Cariamiformes): first mitochondrial genome analysis and morphological description of a leucocytozoid in Brazil

Parasitology, 2023
The distribution of avian haemosporidians of the genus Leucocytozoon in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative ...

Insights into the Biology of Leucocytozoon Species (Haemosporida, Leucocytozoidae): Why Is There Slow Research Progress on Agents of Leucocytozoonosis?

Microorganisms, 2023
Blood parasites of the genus Leucocytozoon (Leucocytozoidae) only inhabit birds and represent a readily distinct evolutionary branch of the haemosporidians (Haemosporida, Apicomplexa).

Exo-erythrocytic development of Leucocytozoon parasites (Haemosporida, Leucocytozoidae) in song thrushes Turdus philomelos

International Journal for Parasitology: Parasites and Wildlife, 2023
Leucocytozoon parasites (Haemosporida, Leucocytozoidae) are haemosporidians whose diversity, exo-erythrocytic development and potential vectors are the least studied. The knowledge about their exo-erythrocytic development and pathogenicity is fragmentary,
