| چکیده | ||
| انگلها به عنوان عوامل مهمی در ایجاد بیماریها و ضایعات در دامها شناخته شده اند. مطالعه حاضر با هدف بررسی شیوع ضایعات انگلی در کبد دامهای کشتار شده در کشتارگاه نیمهصنعتی شوشتر به روش مقطعی و توصیفی روی 450 رأس دام در سال 1401 انجام شد. نمونهها برای بررسی میکروسکوپی به آزمایشگاه ارسال و با استفاده از روشهای مختلف مانند برش و رنگ آمیزی، شیوع ضایعات انگلی در کبد دامها بررسی شد. شیوع انگل دیکروسلیوم و فاسیولا و کیست هیداتید در دامهای شهرستان شوشتر به ترتیب 4/12، 3/11 و 9/12 درصد برآورد شد. نتایج نشان داد ارتباط آماری معنی داری بین نوع حیوان و احتمال درگیری با انگل دیکروسلیوم و فاسیولا وجود ندارد (05/0<P). در حالیکه احتمال آلودگی به کیست هیداتید در گوسفندها بیشتر از گاوها و بزها بود (05/0>P). احتمال درگیری با انگل دیکروسلیوم، فاسیولا و کیست هیداتید در دو جنس به لحاظ آماری یکسان بود (05/0<P). به علاوه مشخص شد که احتمال آلودگی به هر سه انگل در حیوانات بیشتر از 2 سال نسبت به حیوانات کمتر از 2 سال بیشتر است (05/0>P). یافتههای بدست آمده نشان می دهد که میزان بروز انگل دیکروسلیوم و فاسیولا و کیست هیداتید در دامهای شهرستان شوشتر قابل توجه است. همچنین میزان بروز کیست هیداتید در گوسفندها بسیار شایعتر از سایر انواع دام بود. ضایعات هیستوپاتولوژیک نفوذ سلولهای التهابی و تشکیل بافت فیبروز در نمونههای کبد مبتلا را نشان میدهد. بالا رفتن سن یک عامل خطر اصلی در بروز بیماری های انگلی میباشد. بنابراین ضروری است دامداران با استفاده از استراتژیهای کنترل و پیشگیری موجب کاهش معنی دار بیماریهای انگلی در دام ها شوند. | ||

| 39 Parasites are recognized as significant contributors to diseases and lesions in livestock. This study aimed to investigate the prevalence of parasitic lesions in the livers of animals slaughtered at the Shushtar semi-industrial slaughterhouse. The study was carried out in a cross-sectional and descriptive manner on 450 animals slaughtered at the Shushtar semi-industrial slaughterhouse in 1401. The samples were sent to the laboratory for microscopic examination. Various methods such as cutting, staining, and microscopy were used to investigate the prevalence of parasitic lesions in the animals’ livers. The prevalence of Dicrocelium and Fasciola parasites, as well as hydatid cysts, in the livestock of Shushtar city were estimated to be 12.4%, 11.3%, and 12.9% respectively. The study found no statistically significant relationship between the type of animal and the likelihood of infection with Dicrocelium and Fasciola parasites (P<0.05). However, the probability of infection with hydatid cysts was higher in sheep than in cows and goats (P<0.05). The likelihood of infection with Dicrocelium, Fasciola, and hydatid cyst parasites was statistically similar in both sexes (P<0.05). Furthermore, it was discovered that the probability of infection with all three parasites is higher in animals older than 2 years compared to those less than 2 years old (P<0.05). The findings from this study indicate that the incidence of Dicrocelium and Fasciola parasites, as well as hydatid cysts, in the livestock of Shushtar city is significant. Moreover, the rate of hydatid cyst occurrence in sheep was found to be much higher than in other types of livestock. Histopathological lesions show inflammatory cell infiltration and fibrotic tissue formation in affected liver samples. Increasing age was identified as a major risk factor for the occurrence of parasitic diseases. | ||
