| leucocytozoon fringillinarum and leucocytozoon dubreuili in turdus fuscater from a colombian páramo ecosystem. | leucocytozoon spp. infections have been rarely studied in neotropical countries. the apparently low prevalence of these parasites compared to the nearctic regions suggests the absence of competent vectors; however, a 21.3% overall prevalence has recently been reported in non-migratory birds from the páramo region of chingaza national natural park (nnp), where turdus fuscater (great thrush) is the species most frequently infected by these parasites. the present study provides the descriptions of ... | 2013 | 23046497 |
| identification of plasmodium (haemamoeba) lutzi (lucena, 1939) from turdus fuscater (great thrush) in colombia. | this study reports a 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 cordillera of colombia at 2,560 m asl (meters above sea level) with an average annual temperature of 15 c. in total, 156 specimens of birds belonging to 25 species and 14 families were captured using mist nets. the blood samples were collected through venipuncture and analyzed by light microscopy. plasmodium ( ... | 2013 | 23517409 |
| description and molecular characterization of plasmodium (novyella) unalis sp. nov. from the great thrush (turdus fuscater) in highland of colombia. | 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). illustrations of blood stages of new species are given, and the phylogenetic analysis identifies closely related species and lineages of avian malaria parasites. ... | 2013 | 24048707 |
| molecular and morphological characterization of a brazilian lineage of plasmodium (novyella) unalis in turdus spp. (passeriformes) of the atlantic forest, with remarks on new hosts and high genetic variation. | plasmodium spp. are haemosporidian protozoans that alternate their live cycles between bloodsucking culicidae dipterans and vertebrate hosts (mammals, reptiles and birds). in birds, these parasites are the causative agents of the so called avian malaria, a disease associated with considerable declines and extinctions in the avifauna in different geographical regions. in this work, we applied a multidisciplinary approach, light microscopy and cytochrome oxidase b (cyt b) gene sequence analysis fo ... | 2017 | 28930498 |
