尽管有许多关于禽类血液寄生虫的研究，但我们对热带鸟类血孢子虫感染模式的驱动机制仍知之甚少，包括性别、年龄和季节性的影响。使用分子和形态方法检测血液寄生虫，我们发现在巴西中部的一个种群中，幼年白带Tanagers(Neothraupis Fasciata(Lichstein，1823))的血孢子虫感染率低于成虫。然而，没有发现性别或季节性差异。在被分析的92名白带病患者中，67人(患病率为72.8%)感染了血蛋白或疟原虫(球虫门、球虫纲、血孢子目)。对线粒体细胞色素b基因的一部分进行了测序，发现了六个血孢子虫谱系：两个属于血蛋白属，四个属于疟原虫属。疟原虫和血蛋白原虫的患病率分别为43.5%和17.4%。我们的结果表明……
Despite many studies on avian blood parasites, we still have a limited understanding of the mechanisms that drive patterns of haemosporidian infection among tropical birds, including effects associated with sex, age, and seasonality. Using molecular and morphological methods for blood-parasite detection, we found that juvenile White-banded Tanagers (Neothraupis fasciata (Lichtenstein, 1823)) had lower haemosporidian prevalence than adults in a population within central Brazil. However, no sex or seasonal differences were detected. Of the 92 White-banded Tanagers analyzed, 67 individuals (72.8% prevalence) were infected with either Haemoproteus or Plasmodium (phylum Sporozoa, class Coccidea, order Haemosporida). Sequencing of a portion of the mitochondrial cytochrome b gene revealed six haemosporidian lineages: two lineages within the genus Haemoproteus and four within the genus Plasmodium. The prevalences of Plasmodium and Haemoproteus parasites were 43.5% and 17.4%, respectively. Our results suggest that...
