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 ...

Host–parasite oxidative arms race: who will win?

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Avian haemosporidian parasites are globally widespread with a broad repertoire of hosts. When infected, the host can either reduce (resistance) and/or limit the severity of parasitaemia (tolerance). Oxidative stress plays a pivotal role in the host's resistance and tolerance, as well as its detrimental endpoints.

Energetic and oxidative costs of microfilarial infection: evidence for fitness trade‐offs in male village weavers of the Amurum Forest Reserve

Wildlife Biology, Volume 2026, Issue 1, January 2026.
Microfilariae contribute to a higher energetic demand that could lead to oxidative damage and reduce hosts' fitness. Yet reports about the energy status and oxidative stress‐defense mechanisms of infected wild birds are rarely documented. We investigated the relationship between microfilariae and the energy status and oxidative damage‐defense ...

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 ...

WIMANET: The Power of a Network in Wildlife Malaria Research

Integrative Zoology, Volume 21, Issue 1, Page 11-16, January 2026.
The Wildlife Malaria Network (WIMANET) is an EU‐COST funded global network of researchers and stakeholders interested in wildlife malaria and related haemosporidian parasites. In this paper, we review WIMANET's activities to date. We hope this encourages new members to join the network and motivates both new and existing members to participate in its ...

Is it best on the nest? Effects of avian life-history on haemosporidian parasitism

International Journal for Parasitology: Parasites and Wildlife, 2020
Infectious diseases vary in prevalence and pathology among host species. Species may differ in prevalence of infection due to varying exposure and susceptibility to disease agents throughout their lifetime, which may be attributable to underlying ...

Host associations, biogeography, and phylogenetics of avian malaria in southern African waterfowl [PDF]

, 2012
The relevance of spatial variation in the environment and host communities for parasite community composition is poorly documented, creating a need for additional case studies from which general principles can be developed.

Polychromophilus spp. (Haemosporida: Plasmodiidae): First Molecular Detection in Bat Flies From Brazilian Bats

Integrative Zoology, Volume 21, Issue 1, Page 137-150, January 2026.
This study identifies Polychromophilus sp. in blood‐feeding flies (Basilia speiseri and Basilia lindolphoi) from Myotis nigricans bats in Brazil, marking the first molecular detection of the parasite in an insect vector in this country. Two haplotypes were identified, both within the Polychromophilus murinus group.

Testing Local Adaptation in a Natural Great Tit-Malaria System: An Experimental Approach. [PDF]

, 2015
Finding out whether Plasmodium spp. are coevolving with their vertebrate hosts is of both theoretical and applied interest and can influence our understanding of the effects and dynamics of malaria infection. In this study, we tested for local adaptation

Leucocytozoon spp. infection in Accipitriformes birds in Iran [PDF]

Journal of Parasitic Diseases, 2016
Leucocytozoon spp. (Haemosporida, Leucocytozoidae) are vector-borne parasites of various birds. Leucocytozoon can infect different reticuloendothelial tissues and blood cells of birds. In this study peripheral blood samples were collected from Accipitriformes birds [three marsh harriers (Circus aeruginosus) and one tawny eagle (Aquila rapax)] in one ...
