There are 10 officially recognized genotypes (G1-G10) of this parasite.\n\nAim: \nThe current study aimed to sequence and characterize the genotypes of E. granulosus using the antigen B subunit 2 gene isolated from sheep in Al-Diwaniyah City, Iraq.\n\nMethods: \nUsing specific antigen B subunit-2, 50 hydatid cysts were collected from the livers of sheep at a local slaughterhouse between March and October 2023. DNA was obtained from the hydatid fluid of sheep cysts. Protescolices from fertile cyst fluid were also obtained. Conventional PCR targeting the Antigen B gene was performed on the extracted DNA of samples. PCR was performed followed by sequencing and phylogenetic analysis of PCR 7 positive isolates. \n\nResults: \nThe predominant genotype in the sheep population was the G1 strain. Furthermore, the sequenced isolates exhibited a high degree of correlation with local and regional Iran E. granulosus sequences, demonstrating genetic diversity compared with reference strains. The current isolates were assigned accession numbers by the NCBI as follows: OR232318.1, OR232319.1, OR232320.1, OR232321.1, OR232322.1, OR232323.1, and OR232324.1.\n\nConclusion: \nThe findings indicate that E. granulosus has diverse genotypes and is mostly linked genetically to isolates from neighboring countries, such as Brazil and Iraq.<\/jats:p>","DOI":"10.5455\/ovj.2025.v15.i2.52","type":"journal-article","created":{"date-parts":[[2025,3,9]],"date-time":"2025-03-09T20:12:41Z","timestamp":1741551161000},"page":"1","source":"Crossref","is-referenced-by-count":0,"title":["&lt;b&gt;Phylogenetic analysis and genetic evaluation of the &lt;i&gt;Echinococcus granulosus&lt;\/i&gt; antigen B subunit 2 gene isolated from sheep in Al-Diwaniyah, Iraq&lt;\/b&gt;"],"prefix":"10.5455","author":[{"given":"Weam","family":"Hamad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thanaa","family":"Jawad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wegdan","family":"Atiya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Open Veterinary Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/100\/100-1729866699_TYP.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:18:14Z","timestamp":1791483494000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/100\/100-1729866699.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"0","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.5455\/ovj.2025.v15.i2.52","relation":{},"ISSN":["2226-4485"],"issn-type":[{"value":"2226-4485","type":"print"}],"subject":[],"published":{"date-parts":[[2025]]}}}
