Eretmochelys imbricata (hawksbill turtle) is classified as a critically endangered species at world level; in Brazil, it is listed among the threatened species. Spirorchiids are parasites of the circulatory system of chelonians which may cause serious lesions in the various tissues of the host due to deposition of eggs in the bloodstream. In this context, the aim of the present study was to describe the pathology caused by spirorchiid eggs in E. imbricata from the Brazilian over a five year period. A total of 29 animals were analyzed, of which nine (31%) presented lesions associated to spirorchiids eggs. The lesions were: granulomatous enteritis in six (66.66%), granulomatous splenitis in five (55.55%), granulomatous hepatitis in three (33.33%), granulomatous pneumonia in three (33.33%), granulomatous pancreatitis in two (22.22%), and granulomatous adrenalitis in one specimen (11.11%). Concluded the main lesion in Eretmochelys imbricata was giant-cell granulomatous inflammatory reaction to the parasite's eggs. Animals exhibiting poor physical health were more susceptible to presenting such lesions.
玳瑁(hawksbill turtle)被列为世界范围内极危物种;在巴西,它被列为受威胁物种。螺旋体是海龟循环系统的寄生虫,由于其卵在血液中沉积,可能会导致宿主的各种组织发生严重病变。在这种情况下,本研究旨在描述巴西玳瑁在五年内由螺旋体卵引起的病理学变化。共分析了 29 只动物,其中 9 只(31%)出现了与螺旋体卵相关的病变。这些病变包括:6 只(66.66%)存在肉芽肿性肠炎,5 只(55.55%)存在肉芽肿性脾炎,3 只(33.33%)存在肉芽肿性肝炎,3 只(33.33%)存在肉芽肿性肺炎,2 只(22.22%)存在肉芽肿性胰腺炎,1 只(11.11%)存在肉芽肿性肾上腺炎。结论是,玳瑁的主要病变是对寄生虫卵的巨细胞肉芽肿性炎症反应。身体状况不佳的动物更容易出现这种病变。
