Abstract

Acute toxoplasmosis was diagnosed in 3 gray squirrels (Sciurus carolensis) from Louisiana and Pennsylvania. The predominant lesion was multifocal necrosis in several organs, especially of the lymph nodes. Numerous Toxoplasma gondii tachyzoites were seen in lesions, and the diagnosis was confirmed immunohistochemically by reaction with polyclonal T. gondii-specific antibodies. Tissue cysts were seen in several organs, including lung alveoli. The presence of tissue cysts in alveoli of pet squirrels maybe of public health concern if tissue cysts excreted in nasal secretions are swallowed by children.

摘要

在来自路易斯安那州和宾夕法尼亚州的3只灰松鼠（Sciurus carolensis）中诊断出急性弓形虫病。主要病变是多个器官出现多灶性坏死，尤其是淋巴结。在病变中可见大量刚地弓形虫速殖子，通过与多克隆刚地弓形虫特异性抗体反应进行免疫组织化学确诊。在包括肺泡在内的多个器官中发现了组织包囊。如果宠物松鼠肺泡中的组织包囊随鼻分泌物排出后被儿童吞咽，可能会引起公共卫生问题。
