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

Annals 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,

Identification and Prevalence of Blood Protozoa on Culling Layer Hen Sold in Wonokromo Traditional Market Surabaya City

Journal of Parasite Science, 2022
The most common types of blood protozoa in chickens are from the phylum of Apicomplexa, including Plasmodium, Leucocytozoon and Haemoproteus. Blood protozoan diseases can cause decreased egg production, stunting and death in poultry farms.

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

International 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 ...

Blood Parasites in Domestic Birds in Central Iran

Veterinary 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

Haemoparasites in endemic and non-endemic passerine birds from central Mexico highlands

International Journal for Parasitology: Parasites and Wildlife, 2020
Haemosporidian parasites of birds are found worldwide and include the genera Haemoproteus, Plasmodium and Leucocytozoon. Infection with haemosporidian parasites can affect host physical condition and reproductive success.

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Leucocytozoonosis in Domestic Birds in Southwestern Iran: An Ultrastructural Study

Iranian Journal of Parasitology, 2013
Background: Leucocytozoonosis is a disease of birds caused by obligate intracellular protozoa of the genus Leucocytozoon. We determined the prevalence of Leucocytozoon spp.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Genetic diversity and host specificity varies across three genera of blood parasites in ducks of the Pacific Americas Flyway.

PLoS ONE, 2015
Birds of the order Anseriformes, commonly referred to as waterfowl, are frequently infected by Haemosporidia of the genera Haemoproteus, Plasmodium, and Leucocytozoon via dipteran vectors.

Host Cells of Leucocytozoon (Haemosporida, Leucocytozoidae) Gametocytes, with Remarks on the Phylogenetic Importance of This Character

Pathogens, 2023
Leucocytozoon parasites remain poorly investigated in comparison to other haemosporidians. The host cell inhabited by their blood stages (gametocytes) remains insufficiently known.
