The genus comprises numerous widely distributed parasites which have been less investigated than other avian hemoprotozoa. Their occurrence is common, with very variable prevalence values and pathogenicity degrees. species are characterized by a great taxonomic diversity, and infections are usually restricted to birds of the same family. In the present paper, a mixed hemosporidia infection by and sp. in an adult male merlin () which died during hospitalisation is reported, indicating, for the first time, a newly described avian host species. A molecular investigation was carried out through b gene analysis, revealing a 100% match with and spp. A blood smear examination allowed us to detect fusiform mature gametocytes and different degrees of maturity of gametocytes. Histopathology revealed foci of necrosis, hemorrhagic areas and extramedullary hematopoiesis in the liver, the presence of microthrombi in the heart and lung and scattered hemorrhages in the lung.
该属包含众多广泛分布的寄生虫，与其他鸟类血液原虫相比，对它们的研究较少。它们的出现很常见，流行率值和致病程度差异很大。该属物种具有很大的分类学多样性，感染通常局限于同一家族的鸟类。在本文中，报告了一只成年雄性矛隼（Falco columbarius）在住院期间死亡，其感染了由Plasmodium和Haemoproteus属物种引起的混合血孢子虫感染，首次表明了一种新描述的鸟类宿主物种。通过细胞色素b基因分析进行了分子研究，结果显示与Plasmodium和Haemoproteus属物种100%匹配。血液涂片检查使我们能够检测到梭形成熟配子体以及不同成熟度的Haemoproteus配子体。组织病理学显示肝脏中有坏死灶、出血区和髓外造血，心脏和肺中有微血栓，肺中有散在出血。
