Avian malaria in birds from Atlantic Rainforest: a record of Plasmodium cathemerium and other novel lineages [PDF]

Anais da Academia Brasileira de Ciências
Parasitic diseases, like avian malaria, play a relevant impact on wild avifauna around the world, putting a threat to biodiversity, principally in endemic zones.

Increase of avian Plasmodium circumflexum prevalence, but not of other malaria parasites and related haemosporidians in northern Europe during the past 40 years

Malaria Journal, 2022
Background Malaria is a health problem not only in human and veterinary medicine, but also in wildlife. Several theoretical studies have suggested that avian malaria transmission might be increasing in Europe.

The Avian Transcriptome Response to Malaria Infection [PDF]

Molecular Biology and Evolution, 2015
Malaria parasites are highly virulent pathogens which infect a wide range of vertebrates. Despite their importance, the way different hosts control and suppress malaria infections remains poorly understood. With recent developments in next-generation sequencing techniques, however, it is now possible to quantify the response of the entire transcriptome

Coquillettidia (Culicidae, Diptera) mosquitoes are natural vectors of avian malaria in Africa

Malaria Journal, 2009
Background The mosquito vectors of Plasmodium spp. have largely been overlooked in studies of ecology and evolution of avian malaria and other vertebrates in wildlife. Methods Plasmodium DNA from wild-caught Coquillettidia spp.

Culex quinquefasciatus: status as a threat to island avifauna and options for genetic control

CABI Agriculture and Bioscience, 2021
The avifauna endemic to islands is particularly susceptible to population declines and extinctions resulting from the introduction of non-native pathogens.

Physiological and morphological correlates of blood parasite infection in urban and non-urban house sparrow populations.

PLoS ONE, 2020
In the last decade, house sparrow populations have shown a general decline, especially in cities. Avian malaria has been recently suggested as one of the potential causes of this decline, and its detrimental effects could be exacerbated in urban habitats.

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

Integrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Fostering real-time climate adaptation: Analyzing past, current, and forecast temperature to understand the dynamic risk to Hawaiian honeycreepers from avian malaria

Global Ecology and Conservation, 2020
Various vector control options are increasingly being considered to safeguard forest birds in their natural habitats from avian malaria transmission.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...
