Rare Case of Echinostoma cinetorchis Infection, South Korea

![Phylogenetic trees of a worm identified as Echinostoma cinetorchis removed during colonoscopy from a 69-year-old woman in South Korea (red text). Trees were based on nucleotide sequences of the NADH dehydrogenase 1 gene (A), cytochrome c oxidase subunit 1 mitochondrial gene (B), and internal transcribed spacer region (C) of the worm in comparison with various echinostome species deposited in GenBank (accession numbers shown), inferred by the neighbor-joining method (1,000 bootstrap replications) using the Geneious Prime Program 2023.1.2. (Geneious, https://www.geneious.com). Echinoparyphium aconiatum (NADH dehydrogenase 1 and cytochrome c oxidase subunit 1 mitochondrial genes) and Echinoparyphium sp. (internal transcribed spacer) were used as the outgroups. Scale bars indicate evolutionary distance.](/eid/images/24-0289-F2.jpg)
