Avian haemosporidian parasites have been scarcely studied in the Neotropical highlands despite the high avian diversity reported and the uniqueness of these ecosystems. The aims of this study were to examine Haemoproteus and Plasmodium diversity based on morphological and molecular data, as well as to explore the concordance between these two appro...

The high avian biodiversity present in the Neotropical region offers a great opportunity to explore the ecology of host-parasite relationships. We present a survey of avian haemoparasites in a megadiverse country and explore how parasite prevalences are related to physical and ecological host characteristics. Using light microscopy, we documented t...

Plasmodium (Novyella) unalis sp. nov. was found in the Great Thrush, Turdus fuscater (Passeriformes, Turdidae) in Bogotá, Colombia, at 2,560 m above sea level where the active transmission occurs. This parasite is described based on the morphology of its blood stages and a fragment of the mitochondrial cytochrome b gene (lineage UN227). Illustratio...

Abstract This study reports both broadening of the altitudinal range and a new host for Plasmodium (Haemamoeba) lutzi in Colombia. The study was conducted in the city of Bogotá, located in the eastern range of Colombia at 2560 m asl (meters above sea level) with an average annual temperature of 15°C. One hundred fifty six specimens of birds belongi...

We describe Leucocytozoon quynzae sp. nov. (Haemosporida, Leucocytozoidae), which is the first Leucocytozoon parasite identified to species level in hummingbirds. It was found in the Amethyst-throated Sunangel (Heliangelus amethysticollis, Trochilidae, Apodiformes) captured in the Palacio Forest, which belongs to the damping zone of Chingaza Nation...

Traditional ecological knowledge of indigenous groups in the southeastern Colombian Amazon coincides in identifying the two main hydrological transition periods (wet-dry: August-November; dry-wet: March-April) as those with greater susceptibility to disease in humans. Here we analyze the association between indigenous knowledge about these two peri...

The Neotropics are highly diverse in avian species. Neotropical countries contribute a large part of the estimated diversity of haemosporidian parasites reported for the planet’s tropical zones. However, sampling is limited and biased, illustrated by only 30% of the genetic records (barcodes) from non-passerines, most of them not linked to a nomina...

Haemosporidian genera Plasmodium , Haemoproteus and Leucocytozoon , responsible for avian malarial infections, are highly diverse and have a wide range of health effects and predictors, depending on the host and its environmental context. Here, we present, for the first time, detailed information on the identity, prevalence and parasitaemia of haem...

Avian haemosporidian from the genera Haemoproteus and Plasmodium are a diverse and widely distributed group of vector-borne blood parasites. These parasites can have negative effects on bird survival by influencing several aspects of their life cycle, causing different clinical signs and even death. Colombia has the widest range of bird richness th...

Currently, there are three recognized species of haemoproteids infecting Anseriformes: Haemoproteus nettionis, H. macrovacuolatus, and H. greineri. Unfortunately, genetic information associated with a morphotype is available only for H. macrovacuolatus. We recently found a parasite morphologically compatible with Haemoproteus gabaldoni, a species B...

The family Apodanthaceae comprises two genera (Apodanthes and Pilostyles) and 11 endoparasitic species, all of them lacking root and shoot apical meristems, stems, and leaves. Their vegetative phase is reduced to a mycelium-like endophyte formed by strands of parenchyma cells that are in close contact to the host vasculature. These plants become ap...

Guías etnobiológicas de Colombia es una publicación periódica, que nace como resultado de las investigaciones multidiciplinares del grupo estudiantil "MUI" de la Facultad de Ciencias de la Universidad Nacional de Colombia. El objetivo de estas guías de campo es mostrar la cosmovisión de grupos étnicos y resaltar la importancia de su conservación cu...

Colombia is a megadiverse country with about 600 species of reptiles; however, there are few studies on species of hemoparasites found in this taxonomic group. Here, we document the presence of Plasmodium spp. in four species of reptiles from the northern part of the Orinoco-Amazon region in Colombia. Individuals analyzed in this study were capture...

Colombia es un país megadiverso, el cual posee una gran variedad de fauna de vida silvestre, entre ellos los reptiles, un grupo representativo con cerca de 600 especies, de las cuales 98 se encuentran clasificadas en diversas categorías de amenaza. No obstante, existen pocos estudios que permitan conocer la presencia y distribución de hemoparásitos...

With biological collections it is possible to know biodiversity, to understand the ecological and evolutionary processes that may exist in natural ecosystems because they may give us information about hosts, evolution and trophic relationships. Advances in molecular biology have promoted the haemoparasites trace and the number of lineages reported...

The authors regret the sequence No KF279523, reported in Figure 4 Clade C; is a sequence of Haemoproteus syrnii from Strix aluco, not Haemoproteus ilanpapernai. That error does not affect the conclusions of the article. The authors would like to apologise for any inconvenience caused.

Studies of the lowland avifauna in the Neotropical Region have shown a paucity of Leucocytozoon species. However, surveys conducted in the Colombian highlands revealed a great diversity of these parasites infecting resident birds. To further investigate the relationship between Leucocytozoon diversity, the potential vectors, and altitudinal distrib...

The evolutionary origin of wildlife and human malaria parasites (Plasmodium spp.) has been discussed for several decades. The lack of genomic data about species of wildlife haemosporidian parasites related to Plasmodium limits the number of taxa available for phylogenetic analysis. Genomic data about avian parasites of the genus Haemoproteus parasi...

We describe morphologically unique Leucocytozoon pterotenuis sp. nov. (Haemosporida, Leucocytozoidae), the first reported leucocytozoid species developing in fusiform host cell found in a Neotropical passeriform bird. The type host of this parasite is the Chestnut-crowned Antpitta (Grallaria ruficapilla, Grallariidae), an elusive native passerine b...

El Neotrópico presenta una de las avifaunas más ricas del mundo asociada a la gran variedad de ecosistemas producto de la heterogeneidad topográfica y climática. Como parte de esta zona megadiversa, los Andes colombianos representan un escenario prometedor para la investigación en hemoparásitos aviares, poco estudiados en tierras altas en todo el m...

Abstract Plasmodium (Novyella) homopolare, a newly described Plasmodium species, was found in a wide range of Passeriformes species in California, USA, and Colombia. This parasite infected more than 20 % of the sampled bird community (N = 399) in California and was found in 3.6 % of birds sampled (N = 493) in Colombia. Thus far, it has been confirm...

In order to characterize the transmission cycles of Leucocytozoon in Colombian highlands, There were examined 505 birds, of which Opisthoprora euryptera, Margarornis squamiger, Mecocerculus leucophrys, Turdus fuscater, Turdus serranus, Buthraupis montana, Diglossa cyannea, Dubusia taeniata, Hemispingus verticalis, Iridosornis rufivertex, Atlapetes...

Leucocytozoon sp. es un hemoparásito asociado con grandes pérdidas económicas en Japón, Canadá y EEUU. Una alta frecuencia de este hemoparásito fue registrada en el PNN Chingaza ubicado a tres horas de la ciudad de Bogotá. Así mismo se han encontrado formas compatibles con esquizontes de este parásito en tejidos de pollos de granjas avícolas ubicad...
