Do avian blood parasites influence hypoxia physiology in a high elevation environment?

BMC Ecology, 2018
Background Montane birds which engage in elevational movements have evolved to cope with fluctuations in environmental hypoxia, through changes in physiological parameters associated with blood oxygen-carrying capacity such as haemoglobin concentration ...

Ecology and conservation biology of avian malaria: Ecology of avian malaria

, 2012
Avian malaria is a worldwide mosquito‐borne disease caused by Plasmodium parasites. 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.

From Africa to Europe: evidence of transmission of a tropical Plasmodium lineage in Spanish populations of house sparrows

Parasites & Vectors, 2019
Background Avian malaria parasites are a highly diverse group that commonly infect birds and have deleterious effects on their hosts. Some parasite lineages are geographically widespread and infect many host species in many regions.

Molecular Prevalence and Haematological Assessments of Avian Malaria in Wild Raptors of Thailand

Birds
Raptors (Accipitriformes, Falconiformes and Strigiformes) are important for ecological niches as bioindicators and an apex predator; however, their global populations have continuously decreased due to human activities, habitat loss and contagious ...

Chickens treated with a nitric oxide inhibitor became more resistant to Plasmodium gallinaceum infection due to reduced anemia, thrombocytopenia and inflammation

Veterinary Research, 2013
Malaria is a serious infectious disease caused by parasites of the Plasmodium genus that affect different vertebrate hosts. Severe malaria leads to host death and involves different pathophysiological phenomena such as anemia, thrombocytopenia and ...

The Difficulties of Ex Situ Conservation: A Nationwide Investigation of Avian Haemosporidia Among Captive Penguins in Japan

Journal of Zoological and Botanical Gardens
Avian malaria has been a continuous problem in both wild and captive populations of penguins throughout the world. In Japan, where there are over 3000 captive penguins, avian malaria (by Plasmodium spp.) and haemoproteosis (by Haemoproteus spp.) have ...
