Avian Haemosporidian parasites - Plasmodium, Haemoproteus, Leucocytozoon and Fallisia - have a wide distribution except for Antarctica. Leucocytozoon sp. has been poorly described in Brazil, and few studies have indicated infections in birds from the Atlantic Forest, Pantanal, Pampa and Amazon biomes. This study describes, for the first time, the occurrence of Leucocytozoon infection in red-legged seriemas (Cariama cristata) in the Brazilian savanna (Cerrado biome) using molecular diagnosis. Leucocytozoon spp. lineage CARCRI01 was detected in three C. cristata, a non-migratory bird, confirming transmission in mid-elevation areas in central Brazil. Further studies are needed to certify whether infections in red-legged seriemas were not abortive and to elucidate Leucocytozoon infection at low altitudes in the Brazilian lands.
禽血孢子虫寄生虫 - 疟原虫、疟原虫、白细胞和法尔西亚 - 除南极洲外分布广泛。在巴西，白细胞寄生虫的描述很差，很少有研究表明大西洋森林、潘塔纳尔、潘帕斯和亚马逊生物群落的鸟类感染。本研究首次使用分子诊断描述了巴西稀树草原（塞拉多生物群落）中红腿蛇鹫（Cariama cristata）白细胞感染的发生。在三只 C. cristata 中检测到白细胞寄生虫 CARCRI01 谱系，这是一种非迁徙鸟类，证实了在巴西中部中海拔地区的传播。需要进一步的研究来证实红腿蛇鹫的感染是否没有夭折，并阐明巴西低海拔地区的白细胞感染情况。
