The common Buzzard () was previously shown to transmit two species ( and ) forming cysts in the brains of rodents. Due to a lack of research, the richness of species spread by these birds of prey is expected to be much higher. A total of 30 samples of the small intestine of the Common Buzzard were collected in Lithuania and subjected to species identification based on nested PCR of rRNA and , following the sequencing of amplified DNA fragments. Six known spp., , , , , , and , along with three genetically distinct species ( sp. Rod3, sp. Rod4, and sp. Rod5), were identified. Phylogenetically, these three potentially new species clustered with spp. characterised by a rodents-birds life cycle. spp. employing rodents and birds as their intermediate hosts were detected in 66.7% and 50.0% of samples, respectively. These findings are consistent with the diet preferences of Common Buzzards. Notably, co-infections with two or more species were observed in a half of the samples. Altogether, the obtained results indicate that the Common Buzzard could serve as definitive host of various species.
普通鵟（）先前已被证明能传播两种可在啮齿动物大脑中形成囊肿的物种（和）。由于缺乏研究，预计这些猛禽传播的物种丰富度要高得多。在立陶宛共收集了30份普通鵟小肠样本，并基于rRNA和的巢式PCR对扩增的DNA片段进行测序后，对样本进行物种鉴定。鉴定出了六种已知的物种，，，，，，以及，还有三个基因上不同的物种（物种Rod3、物种Rod4和物种Rod5）。在系统发育上，这三个潜在的新物种与以啮齿动物 - 鸟类生命周期为特征的物种聚集在一起。分别在66.7%和50.0%的样本中检测到以啮齿动物和鸟类为中间宿主的物种。这些发现与普通鵟的饮食偏好一致。值得注意的是,在一半的样本中观察到两种或更多物种的共同感染。总之，所获得的结果表明普通鵟可能是各种物种的终宿主。
