The present study aimed to test intestinal scrapings of the Northern Goshawk () and the Eurasian Sparrowhawk () from Lithuania for . and other species characterised by bird-bird life cycles. The protozoan parasite can cause respiratory and neurological diseases in a variety of birds; however, the distribution of this parasite is not well-examined. species were identified with nested PCR and sequencing of the partial region. Sporocysts and/or sporulated oocysts of spp. were observed in 16 (100%) Northern Goshawks and 9 (56.3%) Eurasian Sparrowhawks. Four species, . , . , . , and . , were confirmed in the Eurasian Sparrowhawk. Apart from the latter four species, . , . , . , and . were established in the Northern Goshawk. A higher prevalence of spp. and species richness in Northern Goshawks is associated with the differences in the diet of two examined species. This study is the first report of . in Lithuania. Furthermore, the genetically distinct species spp. 23LTAcc, which is most closely related to . , was found in three Northern Goshawks.
本研究旨在检测来自立陶宛的苍鹰（Accipiter gentilis）和雀鹰（Accipiter nisus）的肠道刮取物中是否存在隐孢子虫（Cryptosporidium）以及其他以鸟类-鸟类生命周期为特征的隐孢子虫物种。原生动物寄生虫隐孢子虫可在多种鸟类中引起呼吸道和神经系统疾病；然而，这种寄生虫的分布情况尚未得到充分研究。通过巢式PCR和部分18S rRNA区域测序鉴定出隐孢子虫物种。在16只（100%）苍鹰和9只（56.3%）雀鹰中观察到了隐孢子虫属（Cryptosporidium）的孢子囊和/或孢子化卵囊。在雀鹰中确认了4个物种，即微小隐孢子虫（Cryptosporidium parvum）、人隐孢子虫（Cryptosporidium hominis）、火鸡隐孢子虫（Cryptosporidium meleagridis）和鼠隐孢子虫（Cryptosporidium muris）。除了后4个物种外，在苍鹰中还发现了猫隐孢子虫（Cryptosporidium felis）、犬隐孢子虫（Cryptosporidium canis）、猪隐孢子虫（Cryptosporidium suis）和安氏隐孢子虫（Cryptosporidium andersoni）。苍鹰中隐孢子虫属物种的较高流行率和物种丰富度与两种被检测鹰类的饮食差异有关。本研究是立陶宛关于隐孢子虫的首次报告。此外，在3只苍鹰中发现了与微小隐孢子虫关系最为密切的遗传上不同的物种隐孢子虫23LTAcc。
