Abstract:
We report a case of Spirometra infection in a Samar cobra (Naja samarensis) imported from the Philippines, belonging to a zoological collection in the southern United States. Under a poor post-surgical prognosis, the snake was euthanized, and at necropsy plerocercoids of a Diphyllobotriidea were found in its subcutaneous tissues and musculature. Molecular and phylogenetic analyses of the complete cytochrome oxidase c subunit I (cox1) gene of the mitochondrial DNA confirmed that the isolate belonged to the genus Spirometra and was closely related to Spirometra mansoni isolates from Asian countries (bootstrap support = 99.4%). Considering the origin and clinical history and handling of the animal, the snake probably arrived infected in America. We suggest the inclusion of diagnostic imaging in the investigation of sparganosis in research and disease surveillance protocols applied in the pre- and post-quarantine period to asymptomatic animals imported from endemic areas.
摘要:
我们报告了从菲律宾进口的Samar眼镜蛇(Najasamarensis)中的Spirometra感染病例,属于美国南部的动物学收藏。在术后预后不良的情况下,这条蛇被安乐死了,在尸检时,在其皮下组织和肌肉组织中发现了二叶虫的类类。线粒体DNA的完整细胞色素氧化酶c亚基I(cox1)基因的分子和系统发育分析证实,该分离株属于Spirometra属,与亚洲国家的Spirometramansoni分离株密切相关(bootstrap支持=99.4%)。考虑到动物的起源和临床历史和处理,这条蛇很可能感染了美国。我们建议在检疫前和检疫后对从流行地区进口的无症状动物进行研究和疾病监测方案的研究中包括诊断成像。
