“…The overall prevalence (35.3%) observed was similar to other community-level studies that used PCR screening approaches and were performed in tropical habitats of South America [16][17]26]. However, the observed prevalence was higher than that found in previous studies that adopted only blood smear screening approaches [27][28][29][30][31]. Furthermore, considerable differences were observed between our prevalence data and the results reported by Sebaio et al [30], which also sampled birds from southeast Brazil.…”

Southeast Brazil is a neotropical region composed of a mosaic of different tropical habitats and mountain chains, which allowed for the formation of bird-rich communities with distinct ecological niches. Although this region has the potential to harbor a remarkable variety of avian parasites, there is a lack of information about the diversity of malarial parasites. We used molecular approaches to characterize the lineage diversity of Plasmodium and Haemoproteus in bird communities from three different habitats in southeast Brazil based on the prevalence, richness and composition of lineages. We observed an overall prevalence of 35.3%, with a local prevalence ranging from 17.2% to 54.8%. Moreover, no significant association between prevalence and habitat type could be verified (p>0.05). We identified 89 Plasmodium and 22 Haemoproteus lineages, with 86% of them described for the first time here, including an unusual infection of a non-columbiform host by a Haemoproteus (Haemoproteus) parasite. The composition analyses of the parasite communities showed that the lineage composition from Brazilian savannah and tropical dry forest was similar, but it was different from the lineage composition of Atlantic rainforest, reflecting the greater likeness of the former habitats with respect to seasonality and forest density. No significant effects of habitat type on lineage richness were observed based on GLM analyses. We also found that sites whose samples had a greater diversity of bird species showed a greater diversity of parasite lineages, providing evidence that areas with high bird richness also have high parasite richness. Our findings point to the importance of the neotropical region (southeast Brazil) as a major reservoir of new haemosporidian lineages.

“…In spite of that, when assessing the research results from this region, we can find common features. One of them is the low prevalence of protozoan blood parasites ranging from 1.4% to 19.9% (Bennett and Borrero 1976;White et al 1978;Bennett et al 1980;Sousa and Herman 1982;Bennett et al 1991;Young et al 1993;Rodriguez and Matta 2001;Valkiunas et al 2003Valkiunas et al , 2004Matta et al 2004;Basto et al 2006;Londono et al 2007).

“…Infection prevalence by microfilariae in birds of the Neotropical Region ranges from 0.6 to 10.5% (Bennett and Borrero 1976;White et al 1978;Bennett et al 1980;Sousa and Herman 1982;Bennett et al 1991;Young et al 1993;Rodriguez and Matta 2001;Valkiunas et al 2003Valkiunas et al , 2004Matta et al 2004;Basto et al 2006).

We studied blood parasites in wild birds within Hitoy Cerere Biological Reserve and Barbilla National Park in Costa Rica during the rainy season of 2004. We examined blood samples from 248 and 114 birds, respectively. Protozoan parasites of the genus Haemoproteus as well as microfilariae were found. Prevalence of Haemoproteus in birds was 0.8% and 4.4% in Hitoy Cerere and Barbilla, respectively, and differences were significant. Prevalence of infection by microfilariae was 8.1% and 3.5%, respectively, however, differences were not significant. Based on morphological characteristics, we divided microfilariae into two groups and nine morphotypes. In Hitoy Cerere, there were microfilariae of all nine morphotypes whereas in Barbilla we only found two morphotypes.

“…are found throughout the world (Young et al 1993;Murata, 2002;Valkiūnas et al 2004;Reullier et al 2006). Although the haematozoa of Neotropical birds have been surveyed in many areas (Woodworth-Lynas et al 1989;Young et al 1993;Valkiūnas, 1997;Matta et al 2004;Ribeiro et al 2005;Durrant et al 2006;Belo et al 2009), some regions and environments in South America remain poorly studied. For example, little is known about the prevalence of blood parasites of wild birds in Venezuela, particularly from the arid Caribbean coast.…”

Diversity of avian haemosporidians in arid zones of northern Venezuela

et al. 2012

Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall prevalence of parasites was 41%, representing 17 mitochondrial lineages: 7 of Plasmodium and 10 of Haemoproteus. Two parasite lineages occurred in both the eastern and western regions infecting a single host species, Mimus gilvus. These lineages are also present throughout northern and central Venezuela in a variety of arid and mesic habitats. Some lineages found in this study in northern Venezuela have also been observed in different localities in the Americas, including the West Indies. In spite of the widespread distributions of some of the parasite lineages found in northern Venezuela, several, including some that are relatively common (e.g. Ven05 and Ven06), have not been reported from elsewhere. Additional studies are needed to characterize the host and geographical distribution of avian malaria parasite lineages, which will provide a better understanding of the influence of landscape, vector abundance and diversity, and host identity on haemosporidian parasite diversity and prevalence.
