Comparative Analysis of the Exo-Erythrocytic Development of Five Lineages of Haemoproteus majoris, a Common Haemosporidian Parasite of European Passeriform Birds

Pathogens, 2023
Haemoproteus parasites (Apicomplexa, Haemosporida) are widespread pathogens of birds, with a rich genetic (about 1900 lineages) and morphospecies (178 species) diversity. Nonetheless, their life cycles are poorly understood.

Surveillance of avian malaria and related haemoparasites in common terns (Sterna hirundo) on the Atlantic coast of South America

Parasitology, 2023
Haemosporidia (Apicomplexa, Haemosporida) are protozoa that infect vertebrate blood cells and are transmitted by vectors. Among vertebrates, birds possess the greatest diversity of haemosporidia, historically placed in 3 genera: Haemoproteus ...

Exo-Erythrocytic Development of Avian Haemosporidian Parasites in European Owls

Animals, 2022
Avian haemosporidian parasites (Haemosporida, Apicomplexa) are globally distributed and infect birds of many orders. These pathogens have been much investigated in domestic and wild passeriform birds, in which they are relatively easy to access. In birds

Climate‐Driven Increase in Transmission of a Wildlife Malaria Parasite Over the Last Quarter Century

Global Change Biology, Volume 31, Issue 10, October 2025.
Climate warming is shaping ecosystems in several ways, and this includes changes in the dynamics of wildlife disease transmission. Over 26 years, avian malaria parasites have become much more common in a population of blue tits, small songbirds that we surveyed in southern Sweden.

Epidemiological traits of the malaria-like parasite Polychromophilus murinus in the Daubenton’s bat Myotis daubentonii

Parasites & Vectors, 2014
Background The great diversity of bat haemosporidians is being uncovered with the help of molecular tools. Yet most of these studies provide only snapshots in time of the parasites discovered.

Expanding the transgene expression toolbox of the malaria vector Anopheles stephensi

Insect Molecular Biology, Volume 34, Issue 1, Page 104-110, February 2025.
An. stephensi lipophorin (lp) gene fragment drives expression of the ZsYellow marker protein in the fat body of aquatic and adult life stages of An. stephensi validating its utility for expression in these tissues. The lp‐driven expression is distinguishable from the commonly utilised 3xP3 promoter, suggesting that both promoters could be used ...

Experimental manipulation of nest temperature and relative humidity reduces ectoparasites and affects body condition of Blue Tits (Cyanistes caeruleus)

Ibis, Volume 167, Issue 1, Page 212-224, January 2025.
Many models predict changes in the distribution and incidence of diseases associated with climate change. However, studies exploring the effect of microclimatic changes on host–parasite relationships are scarce. In this study, we increased temperature or humidity in Eurasian Blue Tit Cyanistes caeruleus nestboxes during the breeding season, to analyse ...

A morphological survey of avian Haemosporida in Colombian wild birds

Revista Colombiana de Ciencias Pecuarias
Introduction: Infection by protozoan haemoparasites causing malaria in birds is chronic and can lead to physical, reproductive, and behavioral alterations, resulting in a decline in the populations of affected wild birds. Objective: To identify parasitic agents causing avian malaria in a wild bird population in Jardin (Antioquia, Colombia) through ...

Different meal, same flavor: cospeciation and host switching of haemosporidian parasites in some non-passerine birds

Parasites & Vectors, 2014
Background Previous studies have shown that haemosporidian parasites (Haemoproteus (Parahaemoproteus) and Plasmodium) infecting passerine birds have an evolutionary history of host switching with little cospeciation, in particular at low taxonomic levels
