A privately owned 14-month-old intact female red kangaroo (Macropus rufus) was presented for acute onset respiratory distress and lethargy. On presentation, the kangaroo was laterally recumbent, tachypneic, dyspneic, lethargic, and obtunded. Thoracic radiographs revealed a severe diffuse mixed pulmonary pattern (alveolar pattern superimposed on a bronchial pattern) and subjective mild generalized cardiomegaly. Due to the severity of clinical signs and grave prognosis, euthanasia was elected. Postmortem examination was consistent with systemic toxoplasmosis. Histopathology and immunohistochemistry staining on infected tissues confirmed Toxoplasma gondii. This is the first published report of radiographic findings for confirmed toxoplasmosis in a red kangaroo or marsupial.
一只14个月大的雌性野生红袋鼠(赤大袋鼠)因急性呼吸窘迫和嗜睡前来就诊。就诊时,这只袋鼠侧卧,呼吸急促、困难,嗜睡且反应迟钝。胸部X光片显示严重的弥漫性混合肺部影像(肺泡影像叠加在支气管影像上)以及主观判断的轻度全身性心脏肥大。由于临床症状严重且预后不良,决定实施安乐死。尸检结果与全身性弓形虫病相符。对感染组织进行的组织病理学和免疫组织化学染色证实为刚地弓形虫。这是关于红袋鼠或有袋动物确诊弓形虫病的X光检查结果的首篇发表报告。
