en A Study on Prevalence, Morphology and Morphometric of Gongylonema pulchrum in Sheep Slaughtered in Sari, Northern Iran انگل شناسی Parasitology پژوهشي Research <div style="text-align: justify;">Background and Aims: The genus Gongylonema infects the upper digestive tract of birds, mammals, and humans. Livestock parasites, especially in the gastrointestinal tract, have caused irreparable damage, including death, reduced products, and economic losses. The present study aimed to reveal the prevalence and morphological and morphometric study of Gongylonema spp. isolated from the esophagus of slaughtered sheep in Sari, northern Iran. Materials and Methods: Esophagi of 340 sheep were collected from Sari's industrial slaughterhouse during the summer and autumn of 2021 (summer=115, autumn= 225). After longitudinal cutting, the surfaces of the esophageal mucosa were carefully checked under the light. The prevalence of infection was estimated, and the morphometric and morphological characteristics of the isolated worms were investigated using a calibrated light microscope and camera lucida. Results: The prevalence of infection was 7.6% (26 isolates), which was estimated for summer and autumn 12 out of 115 (10.4%) and 14 out of 225 (6.2%), respectively. A comparison of morphological features of nematodes in this study with Gongylonema morphological criteria showed that all of them were Gongylonema pulchrum. Conclusions: In the present study, a moderate gongylonemiasis infection was estimated in the sheep from Sari's industrial slaughterhouse. Morphological examination of the retrieved worms showed characteristic morphologies of Gongylonema pulchrum. To clarify the status of the infection, several morphological and molecular studies should be performed on different types of intermediate and final hosts of the parasite in different parts of the country. </div> Gongylonema pulchrum, Iran, Sheep 166 172 http://ijml.ssu.ac.ir/browse.php?a_code=A-10-483-1&slc_lang=en&sid=1 Tahereh Mikaeili Galeh طاهره میکائیلی قلعه T.mikaeili@yahoo.com 0000-0002-7288-9342 No 1 Department of Basic Medical Sciences, Khoy University of Medical Sciences, Khoy, Iran 2 Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran 1 Department of Basic Medical Sciences, Khoy University of Medical Sciences, Khoy, Iran 2 Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran Maryam Nakhaei مریم نخعی maryamnakhaei1396@gmail.com 0000-0003-3565-8446 No Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran 3 Department of Parasitology, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran 3 Department of Parasitology, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Ahmad Daryani احمد دریانی daryanii@yahoo.com 0000-0001-8571-5803 No Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Shahabeddin Sarvi شهاب الدین سروی shahabesarvi@yahoo.com 0000-0002-3412-1033 No Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Seyed Abdollah Hosseini سید عبداله حسینی hosseini4030@gmail.com 0000-0002-2990-1123 No Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Toxoplasmosis Research Department of Parasitology, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Shirzad Gholami شیرزاد غلامی sgholami200@gmail.com 0000-0003-2429-7702 Yes Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran, Department of Parasitology, School of Medicine, Mazandaran University of Medical Sciences, Sari, Iran Toxoplasmosis Research Center, Mazandaran University of Medical Sciences, Sari, Iran, Department of Parasitology, School of Medicine, Mazandaran University of Medical Sciences, Sari, Iran
