Blood films and selected tissue sections from 270 gray squirrels (Sciurus carolinensis) from 18 sites in 11 southeastern states were examined for Hepatozoan griseisciuri. This parasite was found in 110 (41%) squirrels from 17 of the 18 sites. Data suggested transmission of the parasite apparently occurs throughout the year and increases from spring to late summer. The infection was more prevalent in subadults and adults than in juveniles. Schizogonic stages were found only in the lungs, suggesting this organ is a major site of schizogony. Pathologic changes associated with H. griseisciuri infection were thickening of alveolar walls, eosinophil infiltration, pulmonary congestion and atelectasis.
对来自东南部11个州18个地点的270只灰松鼠（Sciurus carolinensis）的血涂片和选定的组织切片进行了检查，以寻找灰松鼠肝簇虫（Hepatozoan griseisciuri）。在18个地点中的17个地点的110只（41%）松鼠中发现了这种寄生虫。数据表明，该寄生虫的传播显然全年都有发生，并且从春季到夏末有所增加。感染在亚成体和成年松鼠中比在幼年松鼠中更为普遍。裂殖生殖阶段仅在肺部发现，表明该器官是裂殖生殖的主要部位。与灰松鼠肝簇虫感染相关的病理变化包括肺泡壁增厚、嗜酸性粒细胞浸润、肺充血和肺不张。
