In the winter of 2022-2023, hundreds of the Atlantic puffins () appeared dead in the coast of the Canary Islands, a rare event considering their cold-living habits, normally occupying the North Atlantic Ocean. In this work, investigation about the parasites present in the Atlantic puffins found in the biggest islands of the Archipelago was carried out from a population portion. Necropsies of 39 birds were made and, during the examination of the urinary tracts, helminths were found. Morphoanatomical analysis under microscope allowed to identify them into genus with high similarity to After that, DNA was extracted and NADH dehydrogenase subunit 1 gene were amplificated by a polymerase chain reaction method followed by sequencing and phylogenetic analysis. The molecular results demonstrated that in fact was the helminth parasite present in the urinary tracts of the Atlantic puffins found in the Canary Islands.
在2022年至2023年冬季，数百只大西洋海雀在加那利群岛海岸死亡，考虑到它们通常生活在北大西洋寒冷海域的习性，这是一件罕见的事情。在这项工作中，从群岛最大岛屿上发现的大西洋海雀群体中抽取一部分，对其体内存在的寄生虫进行了调查。对39只海雀进行了尸检，在检查其泌尿系统时发现了蠕虫。通过显微镜下的形态解剖分析，将它们鉴定为与 属高度相似的 属。之后，提取DNA，并通过聚合酶链反应方法扩增烟酰胺腺嘌呤二核苷酸脱氢酶亚基1基因，随后进行测序和系统发育分析。分子结果表明，事实上， 是在加那利群岛发现的大西洋海雀泌尿系统中存在的蠕虫寄生虫。
