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 ...

Outbreak of avian malaria associated to multiple species of Plasmodium in magellanic penguins undergoing rehabilitation in southern Brazil. [PDF]

PLoS ONE, 2014
Avian malaria is a mosquito-borne disease caused by Plasmodium spp. Avian plasmodia are recognized conservation-threatening pathogens due to their potential to cause severe epizootics when introduced to bird populations with which they did not co-evolve.

Avian malaria and bird humoral immune response [PDF]

Malaria Journal, 2018
Plasmodium parasites are known to impose fitness costs on their vertebrate hosts. Some of these costs are due to the activation of the immune response, which may divert resources away from self-maintenance. Plasmodium parasites may also immuno-deplete their hosts. Thus, infected individuals may be less able to mount an immune response to a new pathogen

Assessing Risk Thresholds in Controlled Human Infection Models (CHIM)

Bioethics, EarlyView.
ABSTRACT Controlled Human Infection Models (CHIMs) are a type of clinical trial involving deliberately exposing human volunteers to an infectious agent. Compared to studies of natural infection, CHIMs offers distinctive benefits, from the ability to study presymptomatic infection to a direct assessment of the efficacy of vaccines and therapeutics in a ...

High prevalence and lineage diversity of avian malaria in wild populations of great tits (Parus major) and mosquitoes (Culex pipiens).

PLoS ONE, 2012
Avian malaria studies have taken a prominent place in different aspects of evolutionary ecology. Despite a recent interest in the role of vectors within the complex interaction system of the malaria parasite, they have largely been ignored in most ...

Plasmodium relictum infection in Culex quinquefasciatus (Culicidae) decreases diel flight activity but increases peak dusk flight activity

Malaria Journal, 2022
Background Parasites are recognized for their ability to modify host physiology and behaviours in ways that increase parasite fitness. Protozoan parasites of the genus Plasmodium are a group of widespread vector-borne parasites of vertebrates, causing ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

Conservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Characterization of the Plasmodium and Haemoproteus parasite community in temperate-tropical birds during spring migration

International Journal for Parasitology: Parasites and Wildlife, 2021
Animal movements, especially avian migration, can be a mechanism for the large-scale dispersal and geographic range expansion of parasites. The host-parasite relationships among birds during migration have yet to be fully explored.

An updated checklist of Culicoides Latreille, 1809 biting midges from the highlands of eastern Democratic Republic of the Congo Une liste mise à jour des moucherons piqueurs de Culicoides Latreille, 1809 des hautes terres de l'est de la République démocratique du Congo

Medical and Veterinary Entomology, EarlyView.
The highlands of eastern Democratic Republic of the Congo (DRC) are home to critically endangered eastern gorillas (Gorilla beringei). Climate change could increase the abundance and distribution of Culicoides‐borne diseases. We utilized morphological and molecular techniques to identify Culicoides spp.

Ecology and conservation biology of avian malaria [PDF]

Annals of the New York Academy of Sciences, 2012
Avian malaria is a worldwide mosquito‐borne disease caused byPlasmodiumparasites. These parasites occur in many avian species but primarily affect passerine birds that have not evolved with the parasite. Host pathogenicity, fitness, and population impacts are poorly understood.
