MHC-I affects infection intensity but not infection status with a frequent avian malaria parasite in blue tits. [PDF]

PLoS ONE, 2013
Host resistance against parasites depends on three aspects: the ability to prevent, control and clear infections. In vertebrates the immune system consists of innate and adaptive immunity.

Conservation implications of avian malaria exposure for African penguins during rehabilitation

South African Journal of Science, 2017
The African penguin (Spheniscus demersus) is the only penguin species that breeds on the African continent and it is currently classified as endangered. Its conservation is assisted by the Southern African Foundation for the Conservation of Coastal Birds

Microbiomes associated with avian malaria survival differ between susceptible Hawaiian honeycreepers and sympatric malaria‐resistant introduced birds

Molecular Ecology, 2022
Of the estimated 55 Hawaiian honeycreepers (subfamily Carduelinae) only 17 species remain, nine of which the International Union for Conservation of Nature considers endangered.

Keys to the avian malaria parasites

Malaria Journal, 2018
Background Malaria parasites (genus Plasmodium) are widespread in birds. These pathogens cause pathology of blood and various organs, often resulting in severe avian malaria. Numerous recent studies have reported DNA sequences of avian malaria parasites,

Anthropogenic landscape alteration promotes higher disease risk in wild New Zealand avian communities.

PLoS ONE, 2022
Anthropogenic changes can have dramatic effects on wild populations. Moreover, by promoting the emergence of vector-borne diseases in many ecosystems, those changes can lead to local extinction of native wildlife.

Recent advances in the study of avian malaria: an overview with an emphasis on the distribution of Plasmodium spp in Brazil

Memorias do Instituto Oswaldo Cruz, 2011
Avian malaria parasites (Plasmodium) have a worldwide distribution except for Antarctica. They are transmitted exclusively by mosquito vectors (Diptera: Culicidae) and are of particular interest to health care research due to their phylogenetic ...

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.

Avian malaria affecting penguins in zoological gardens, aquariums and wildlife parks in the UK.

The Veterinary Record, 2021
BACKGROUND Avian malaria has caused mortalities in captive penguins worldwide and it is a conservation threat for some wild penguins. The experience of staff working on penguins is highly valuable for the improvement of captivity conditions. METHODS An

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.
