Abstract

ABSTRACT: We detected Neobenedenia girellae infections in 40 species belonging to 12 families of imported marine ornamental fish from a public aquarium in the Mexican state of Yucatan. A total of 348 fish specimens were examined for monogeneans in January 2018 to December 2020. Monogeneans were corroborated morphologically and molecularly with a partial sequence of 28S (region D1–D3) ribosomal DNA and analyzed in a molecular phylogenetic context in combination with other N. girellae sequences available in GenBank. The phylogenetic tree revealed that the specimen found consistently belonged to the N. girellae clade. High infection parameters were detected of N. girellae in most hosts. This identification is relevant to aquarists and aquaculturists in the Gulf of Mexico because N. girellae is considered highly pathogenic in confined fish. This work demonstrates that the importation of ornamental fish coupled with deficient sanitary measures (lack of quarantine areas in distribution centers) contributes to spread of parasites and their establishment within Mexico.

墨西哥尤卡坦进口海洋观赏鱼新记录（哈吉斯，1955）

摘要：我们从墨西哥尤卡坦州的一家公共水族馆检测到了来自12科的40种进口海洋观赏鱼感染了新贝尼德尼亚长颈鹿。2018年1月至2020年12月，共对348个鱼类标本进行了单基因检查。用28S（区域D1-D3）核糖体DNA的部分序列从形态和分子上证实了单基因，并在分子系统发育背景下与GenBank中的其他N.girellae序列相结合进行了分析。系统发育树显示，发现的标本始终属于N.girellae分支。在大多数宿主中检测到高感染参数的N.girellae。这一鉴定与墨西哥湾的养殖者和养殖者有关，因为N.girellae被认为在封闭的鱼类中具有高致病性。这项工作表明，观赏鱼的进口加上卫生措施不足（配送中心缺乏隔离区）导致了寄生虫的传播及其在墨西哥境内的传播。

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
