Diversity, distribution, and methodological considerations of haemosporidian infections among Galliformes in Alaska

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2023
Using samples spanning 10-degrees of latitude in Alaska, we provide the first comparative assessment of avian haemosporidia distribution of Arctic Alaska with subarctic host populations for four species of grouse and three species of ptarmigan ...

Prevalence of Haemosporidian Parasites in an Arctic Breeding Seabird Species—The Red-Throated Diver (Gavia stellata)

open access: yesMicroorganisms, 2022
Haemosporida, vector-transmitted blood parasites, can have various effects and may also exert selection pressures on their hosts. In this study we analyse the presence of Haemosporida in a previously unstudied migratory seabird species, the red-throated ...

Survey of Leucocytozoon in South Carolina

open access: yesPoultry Science, 1976
An extensive survey of birds for Leucocytozoon in South Carolina during the summer of 1972 revealed that Blue Jays, Purple Grackles and domestic chickens were commonly infected. No alternate hosts were found for Leucocytozoon smithi of turkeys.

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

open access: yesGlobal change biology.
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.

Latitudinal gradients of haemosporidian parasites: Prevalence, diversity and drivers of infection in the Thorn-tailed Rayadito (Aphrastura spinicauda)

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2020
Latitudinal gradients are well-suited systems that may be helpful explaining distribution of haemosporidian parasites and host susceptibility. We studied the prevalence, diversity and drivers of haemosporidian parasites (Leucocytozoon, Plasmodium and ...

The Development of a Leucocytozoon of Guinea-Pigs [PDF]

open access: yesAnnals of Tropical Medicine & Parasitology, 1912
Abstract The presence of “bodies” within the large mononuclear leucocytes of guinea-pigs was first noticed by Kurloff (1898). He described them as inclusions; for in a drop of guinea-pig’s blood he noted that many of the large lymphocytes contained, within their cytoplasm, clear, spherical vacuoles which were distinct from the nucleus,

Blood Parasites in Domestic Birds in Central Iran

open access: yesVeterinary Sciences, 2020
Parasites may affect the dynamics of bird populations. Plasmodium, Leucocytozoon and Haemoproteus are well-known avian haematozoa that can trigger decreased productivity and high mortality in domesticated birds. In this study, we evaluated the prevalence
