Molecular analyses on host-seeking black flies (Diptera: Simuliidae) reveal a diverse assemblage of Leucocytozoon (Apicomplexa: Haemospororida) parasites in an alpine ecosystem [PDF]

, 2015
BACKGROUND: Molecular studies have suggested that the true diversity of Leucocytozoon (Apicomplexa: Haemospororida) species well exceeds the approximately 35 currently described taxa.

A New Species of Plasmodium of the Subgenus Novyella Infecting White‐Shouldered Fire‐Eyes (Pyriglena leucoptera) (Aves: Thamnophilidae) in Brazil

Integrative Zoology, Volume 21, Issue 1, Page 192-202, January 2026.
South America has a remarkable genetic diversity of avian haemosporidians, yet only a few species have been described combining molecular and morphological data. This study introduces Plasmodium (Novyella) pyriglenae sp. nov., a new species infecting the white‐shouldered fire‐eye (Pyriglena leucoptera) in Brazil.

Bird Community Composition, Migration, and Environmental Factors Jointly Influence the Global Distribution of Avian Haemosporidian Lineages

Integrative Zoology, Volume 21, Issue 1, Page 60-68, January 2026.
Avian haemosporidians are widely distributed; however, the role of migratory and non‐migratory birds, as well as environmental conditions, is incompletely understood. A histogram of the number of parasite lineages per ecoregion shows the variation in avian haemosporidian richness across space.

Occurrence of leucocytozoon and haemoproteus [PDF]

Annales de Parasitologie Humaine et Comparée, 1984
Blood smears from Falconiformes (91 birds of 10 species) and Strigiformes (23 birds of 5 species) captured in Italy, were examined for haematozoa. Leucocytozoon were found in Falco tinnuculus, Buteo buteo, Circus cyaneus, Circus pygargus, Accipiter nisus from Falconiformes and in Strix aluco, from Strigiformes.

Avian blood parasites in an endangered columbid: Leucocytozoon marchouxi in the Mauritian Pink Pigeon Columba mayeri [PDF]

, 2007
There is increasing evidence that pathogens can play a significant role in species decline. This study of a complete free-living species reveals a cost of blood parasitism to an endangered host, the Pink Pigeon Columba mayeri, endemic to Mauritius.

Detection, prevalence, and transmission of avian hematozoa in waterfowl at the Arctic/sub-Arctic interface: co-infections, viral interactions, and sources of variation [PDF]

, 2016
Background The epidemiology of avian hematozoa at high latitudes is still not well understood, particularly in sub-Arctic and Arctic habitats, where information is limited regarding seasonality and range of transmission, co-infection dynamics with ...

Spatiotemporal Dynamics of Blood Parasite Infections and Impacts on Avian Health and Reproduction

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Parasitic infections are ubiquitous in nature, but their consequences are often difficult to evaluate in wildlife. This is particularly the case for chronic infections for which fitness impacts can be subtle or confounded with other intrinsic and extrinsic factors.

Molecular probes for the identification of avian Haemoproteus and Leucocytozoon parasites in tissue sections by chromogenic in situ hybridization

Parasites & Vectors, 2019
Background Avian haemosporidian parasites can cause severe disease in their hosts due to excessive exo-erythrocytic merogony and anaemia caused by blood stages.

Hematozoa of Common Grackles (Quiscalus quiscula versicolor, Vieillot) in Central Arkansas [PDF]

, 1990
During the years 1977-84, 118 bronzed grackles, Quiscalus quiscula versicolor, Vieillot, of 132 examined were found infected with hematozoa. The eight species of symbionts collected from the infected birds included two microfilarial species (Chandlerella

High rates of infection by blood parasites during the nestling phase in UK Columbids with notes on ecological associations [PDF]

, 2017
Studies of blood parasite infection in nestling birds rarely find a high prevalence of infection. This is likely due to a combination of short nestling periods (limiting the age at which nestlings can be sampled) and long parasite prepatent periods ...
