| effects of spatial and host variables on hematozoa in white-crowned sparrows wintering in baja california. | a survey of blood parasites was conducted in february 1995 on white-crowned sparrows (zonotrichia leucophrys) wintering in two environmentally different localities of baja california sur (mexico). blood parasite prevalence was higher in la purísima (49%) than in san josé del cabo (8%), but there were no differences between ages or sexes within each locality. all haematozoa infections were by haemoproteus coatneyi, except one bird in each site that were positive for trypanosoma sp. we found no ev ... | 2001 | 11763742 |
| paucity of hematozoa in colombian birds. | sixty-four birds of 43 species were caught at six localities in colombia during the dry season in march 1998 and investigated for hematozoa by microscopic examination of stained blood films. haemoproteus coatneyi, plasmodium vaughani, leucocytozoon sp., and microfilariae were identified. the overall prevalence of infection was 8%. prevalences of infection for haemoproteus spp., plasmodium spp., leucocytozoon spp., and microfilariae were 3%, 2%, 2%, and 3%, respectively. all hemosporidian infecti ... | 2003 | 12910776 |
| haemoproteus erythrogravidus n. sp. (haemosporida, haemoproteidae): description and molecular characterization of a widespread blood parasite of birds in south america. | the great diversity of birds and ecosystems in the andean mountains has been understudied in terms of their parasite species. we describe a new haemoproteus parasite, h. (parahaemoproteus) erythrogravidus infecting zonotrichia capensis (rufous-collared sparrow) in south america. the description of this blood parasite species is supported by morphological and molecular data based on a fragment of cytochrome b gene (cyt b) and complete mitochondrial genome sequences. the new species is closely rel ... | 2016 | 26995696 |
| avian haemosporidians from neotropical highlands: evidence from morphological and molecular data. | 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 approaches, when identifying species. we sampled 1487 birds belonging to 166 species, in localities of the colombian andean region at elevations ranging fr ... | 2015 | 25638289 |
