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.

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 ...

Avian malaria is associated with increased reproductive investment in the blue tit

, 2014
Haemosporidians causing avian malaria are very common parasites among bird species. Their negative effects have been repeatedly reported in terms of deterioration in survival prospects or reproductive success.

Automated haematology analysis to diagnose malaria [PDF]

, 2010
For more than a decade, flow cytometry-based automated haematology analysers have been studied for malaria diagnosis. Although current haematology analysers are not specifically designed to detect malaria-related abnormalities, most studies have found ...

Avian Malaria Deaths in Parrots, Europe

Emerging Infectious Diseases, 2011
To the Editor: Avian malaria is an insect-borne disease induced by a so far unknown number of protozoan blood parasites of the genera Plasmodium and Haemoproteus (hematozoa) (1,2). The unintentional introduction of P. relictum to the Hawaiian Islands, USA, has had fatal effects for the native bird fauna (3).

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

Integrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

Impact of bauxite mining on mosquito communities (Diptera: Culicidae) and pathogen transmission risks in the eastern Amazon

Medical and Veterinary Entomology, EarlyView.
Bauxite mining in the Amazon alters mosquito communities, favouring anthropophilic and generalist vectors while reducing species diversity and the variety of blood meal sources. Molecular analyses identified humans, tapirs and deer as the primary blood meal sources.

Population structure of avian malaria parasites

Ecology and Evolution, 2019
AbstractThe geographic distribution of genetic diversity in malaria parasite populations (Apicomplexa: Haemosporida) presumably influences local patterns of virulence and the evolution of host‐resistance, but little is known about population genetic structure in these parasites. We assess the distribution of genetic diversity in the partial Domain I of

Animal Segregation: The Biopolitics of Concentrated Pig Farming

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract This paper explores the possibility to think through the concept of animal segregation to understand the more‐than‐human geographies of livestock animals. By redirecting the analytical tools for studying the spatial separation of humans to the segregation of animals, this paper contributes to understanding the geographical processes of ...
