| 中文描述 | 血色食道蟲(SPIROCERCA LUPI)是一種寄生於肉食動物的寄生蟲。當寄生蟲的仔蟲(Larvae)在組織間移行、仔蟲與成蟲持續存在於組織中，或引發二次性細菌感染時，就會導致臨床症狀發生。若食道寄生蟲，不正常的由狗的食道移行進入氣管或支氣管，會引起肉芽組織的生成，引發呼吸道症狀；症狀的嚴重程度取決於肉芽組織的大小與生成位置。診斷方式可藉由氣管沖洗或糞便沉渣法(Fecal sedimentation)檢查是否有蟲卵；也可能經由放射線學檢查，檢出食道肉芽腫，再使用內視鏡採樣組織檢體，檢驗是否有線蟲存在。有少數報告指出，血色食道蟲可能造成主動脈瘤的血管壁變的脆弱，而引發破裂與急性死亡。被感染的動物，也常在X光檢查中被檢出有後段胸椎的椎體病變，並造成跛腳或其他神經症狀。 |

| 英文描述 | SPIROCERCA LUPI is a parasites of carnivores. The lesions of spirocercosis are due to migration of infective larvae, the continued presence of larvae and adult worms in tissues, and secondary bacterial infections. Aberrant migration of this esophageal worm of dogs into the trachea or bronchi may result in respiratory signs due to granuloma formation. Severity depends on size and site of granuloma formation. Dx by finding eggs in bronchial washings and by finding eggs of the parasite on fecal sedimentation. Esophageal granulomas may be identified using radiography, and esophagoscopy can be used to observe lesions and obtain samples for identification of nematodes in tissue. There are rare reports of sudden death due to rupture of an aortic aneurysm which was associated with weakening of the vessel by SPIROCERCA. Radiologic evidence of spondylitis of the caudal thoracic vertebrae is common and can be associated with lameness or neurologic signs. |
