Avian malaria and invasion success: Contrasting infection patterns in two introduced Eurasian sparrows in North America (Passer domesticus and Passer montanus) [PDF]

open access: yesInternational Journal for Parasitology: Parasites and Wildlife
Biological invasions present a unique context to investigate how parasites influence host establishment and spread. We compared whether the more invasive house sparrow (Passer domesticus, HOSP) showed lower haemosporidian (Plasmodium) infection ...

A New Species of Plasmodium of the Subgenus Novyella Infecting White-Shouldered Fire-Eyes (Pyriglena leucoptera) (Aves: Thamnophilidae) in Brazil. [PDF]

open access: yesIntegr Zool
South America has a remarkable genetic diversity of avian haemosporidians, yet only a few species have been described combining molecular and morphological data. This study introduces Plasmodium (Novyella) pyriglenae sp. nov., a new species infecting the white‐shouldered fire‐eye (Pyriglena leucoptera) in Brazil.

Vector-Borne Blood Parasites of the Great-Tailed Grackle (Quiscalus mexicanus) in East-Central Texas, USA

open access: yesMicroorganisms, 2021
Great-tailed grackles (Quiscalus mexicanus) have dramatically expanded into North America over the past century. However, little is known about the blood that parasites they support.

Bird Community Composition, Migration, and Environmental Factors Jointly Influence the Global Distribution of Avian Haemosporidian Lineages. [PDF]

open access: yesIntegr Zool
Avian haemosporidians are widely distributed; however, the role of migratory and non‐migratory birds, as well as environmental conditions, is incompletely understood. A histogram of the number of parasite lineages per ecoregion shows the variation in avian haemosporidian richness across space.

Analysis of clinical and hematological characteristics and search for hemoparasites in owls (Strigiformes: ‎Strigidae) seized or rescued from the Atlantic Forest biome of the Rio de Janeiro (southeastern Brazil)

open access: yesBioscience Journal, 2023
Hemoparasitism is known to vary according to the presence of vectors and hosts, and hematological examination can be a useful tool for early diagnosis in avian medicine, contributing to monitoring and conservation of bird populations. In this context, we

RESPOSTA IMUNE INATA DE QUIRÓPTEROS EM AMBIENTES ANTROPIZADOS: INFECÇÃO POR HAEMOSPORIDA NA AMAZÔNIA BRASILEIRA

open access: diamondREVISTA FOCO, 2023
O avanço de ações antrópicas próximas às áreas naturais favoreceu um estreito contato entre os humanos e animais silvestres nos seus habitats, propiciando a dispersão de agentes parasitários e infecciosos para novos hospedeiros. Uma grande diversidade de patógenos pode ser encontrada em algumas ordens de animais silvestres, como  a ordem Chiroptera ...

Prevalence and Genetic Diversity of Haemoproteus and Leucocytozoon in Raptors and Other Captive Birds at the National Zoological Garden in South Africa. [PDF]

open access: yesIntegr Zool
Captive birds at the National Zoological Garden in South Africa harbor diverse haemosporidian parasite species and lineages. This might compromise conservation efforts of threatened species. ABSTRACT Avian haemosporidian infections have been associated with disease outbreaks in zoos and rehabilitation centers globally. This study aimed to determine the
