Despite the worldwide distribution of <jats:styled-content style=\"fixed-case\"><jats:italic>T. evansi<\/jats:italic><\/jats:styled-content> infections in equids, surra has not been reported in Arabian horses in Khuzestan Province for over 60\u2009years. In September 2018, a 7\u2010year\u2010old Arabian mare was referred from a 10\u2010horse farm in the suburbs of Ahvaz City. The mare presented with a history of weight loss, poor appetite, and proximity to a camel herd. Physical examination revealed a poor body condition score (BCS\u2009\u2264\u20093\/9), pale conjunctival and oral mucosal membranes, dehydration, tachycardia, and fever. Other horses in the herd also exhibited gradual weight loss and hyporexia, with two fatalities reported. A hematologic examination of the referred mare showed leukopenia, severe anemia, and thrombocytopenia. Microscopic examination of a whole blood smear confirmed severe infection with <jats:italic>Trypanosoma<\/jats:italic>. PCR assessment of a blood sample further confirmed the infection with <jats:styled-content style=\"fixed-case\"><jats:italic>T. evansi<\/jats:italic><\/jats:styled-content>. The referred mare and seven nonreferred patients from the herd received treatment with diminazene diaceturate (5\u2009mg\/kg, a single dose) and penicillin for 4\u2009days. Unfortunately, the referred mare died despite the treatment, while the remaining nonreferred horses recovered. This report marks the first molecular diagnosis of surra in an Arabian horse in Khuzestan Province, highlighting the need for further investigation into surra as a re\u2010emerging disease in this significant population of Arabian horses in the region.<\/jats:p>","DOI":"10.1111\/vcp.70003","type":"journal-article","created":{"date-parts":[[2025,6,12]],"date-time":"2025-06-12T11:06:54Z","timestamp":1749726414000},"page":"186-190","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical occurrence of trypanosomiasis in Arabian horses from Ahvaz"],"prefix":"10.1111","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4837-6766","authenticated-orcid":false,"given":"Ali Abbas","family":"Nikvand","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine Shahid Chamran University of Ahvaz  Ahvaz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seyedeh Missagh","family":"Jalali","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine Shahid Chamran University of Ahvaz  Ahvaz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somayeh","family":"Bahrami","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Veterinary Medicine Shahid Chamran University of Ahvaz  Ahvaz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassan","family":"Rahij Torfi","sequence":"additional","affiliation":[{"name":"Graduated of Veterinary Clinical Pathology, Faculty of Veterinary Medicine Shahid Chamran University of Ahvaz  Ahvaz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,3]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"2156","volume-title":"A Textbook of the Diseases of Cattle, Horses, Sheep, Pigs, and Goats","author":"Constable PD","year":"2017"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-44329-6.00007-3"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.5455\/OVJ.2023.v13.i12.18"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/1475-9292-5-2"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2015.11.016"},{"key":"e_1_2_6_7_1","first-page":"274","volume-title":"Infectious Disease of Camel","author":"Wemery U","year":"2002"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/194176"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2005.73.491"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pntd.0006790"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prevetmed.2019.04.013"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1051\/parasite\/2017024"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00580-016-2345-7"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13071-020-04472-w"},{"key":"e_1_2_6_15_1","unstructured":"Hashemi\u2010FesharakiR Esmaeil\u2010NiaK HabibiGR SarkarzadehP.Investigations on trypanosomosis in equine.
