Morphological and molecular identification was performed to confirm the identity of the <jats:italic>Trichuris<\/jats:italic> specimens obtained from <jats:italic>C. dromedarius.<\/jats:italic> Fifteen male <jats:italic>Trichuris<\/jats:italic> specimens were selected, and molecular identification was performed using mitochondrial cytochrome <jats:italic>c<\/jats:italic> oxidase subunit I, 12S ribosomal RNA, 16S ribosomal RNA genes and the nuclear internal transcribed spacer 2 (ITS2) region. Through phylogenetic analysis, 2 distinct groups were obtained using the mitochondrial genes, where group 1 showed a close relationship to <jats:italic>Trichuris globulosa<\/jats:italic> while group 2 showed a close relationship to <jats:italic>Trichuris ovis<\/jats:italic>, providing molecular evidence of a possible <jats:italic>T. globulosa<\/jats:italic> species complex. Additionally, the nuclear ITS2 region did not provide enough resolution to distinguish between the 2 groups of <jats:italic>Trichuris<\/jats:italic> specimens. Observation of morphological characters revealed variations in the shape of the male spicule sheath, where specimens present either a globular posteriorly truncated swelling or the absence of posteriorly truncated swelling. Moreover, the variations in male spicule sheath does not corroborate with the results of molecular data, suggesting the limited use of this character for identification of <jats:italic>T. globulosa<\/jats:italic>. In conclusion, molecular analysis suggests a possible species complex in <jats:italic>T. globulosa<\/jats:italic>, with the mitochondrial genetic markers successfully differentiating between the 2 groups. The limited use of the male spicule sheath as a diagnostic character for identification of <jats:italic>T. globulosa<\/jats:italic> is suggested.<\/jats:p>","DOI":"10.1017\/s0031182024000374","type":"journal-article","created":{"date-parts":[[2024,3,25]],"date-time":"2024-03-25T07:24:17Z","timestamp":1711351457000},"page":"546-556","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Phylogenetic evidence of a possible <i>Trichuris globulosa<\/i> species complex in Arabian camels from Kuwait"],"prefix":"10.1017","volume":"151","author":[{"given":"Adawia","family":"Henedi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1821-7801","authenticated-orcid":false,"given":"Abigail Hui En","family":"Chan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wessam","family":"Youssef","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoda A.","family":"Taha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urusa","family":"Thaenkham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ameen A.","family":"Ashour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,3,25]]},"reference":[{"key":"S0031182024000374_ref14","first-page":"218","article-title":"Differentiation of Trichuris species using a morphometric approach","volume":"9","author":"Garc\u00eda-S\u00e1nchez","year":"2019","journal-title":"International Journal for Parasitology: Parasites and Wildlife"},{"key":"S0031182024000374_ref27","unstructured":"RStudio Team (2021) RStudio: Integrated Development Environment for R.
