The superficial and deep lymphatic systems of the Australian brushtail possum (Trichosurus vulpecula) are described. In common with other marsupials studied to date and in contrast with most eutherians, there were no popliteal lymph nodes and efferent drainage from the inguinal lymph centre passed directly to the deep axillary group of lymph nodes via an inguinoaxillary trunk. Efferent vessels from the tonsil passed directly to the deep cervical lymph node, which was drained by the tracheal trunk. The mandibular and parotid lymph nodes drained independently to the superficial cervical lymph node. All subcutaneous lymph drainage passed either through the superficial cervical or the axillary lymph centres before entering the venous system, an arrangement which is also found in kangaroos. The significance of the patterns of lesion distributions in possums with naturally occurring tuberculosis caused by Mycobacterium bovis is discussed.
本文描述了澳大利亚帚尾袋貂（Trichosurus vulpecula）的浅淋巴管系统和深淋巴管系统。与迄今为止研究的其他有袋动物相同，与大多数真兽类动物不同，其没有腘淋巴结，腹股沟淋巴中心的输出引流通过腹股沟腋干直接通向腋窝深淋巴结群。扁桃体的输出血管直接通向颈深淋巴结，颈深淋巴结由气管干引流。下颌淋巴结和腮腺淋巴结分别独立引流至颈浅淋巴结。所有皮下淋巴引流在进入静脉系统之前均通过颈浅或腋窝淋巴中心，袋鼠也有这种排列方式。本文还讨论了由牛分枝杆菌引起的自然感染结核病的袋貂病变分布模式的意义。
