Abstract

Background:
Liver lesions in cattle not only have negative effects on the cattle breeding
industry, but also lead to loss of animal protein production, and in particular
to endanger the consumers’ health. OBJECTIVES:
This study was carried out to examine the macroscopic and histopathologic
lesions of liver in slaughtered cattle of Zabol City. METHODS:
Livers of 281 cattle slaughtered at the industrial slaughterhouse of Zabol City
were collected from March to September 2015 for gross and microscopic
investigation. Tissue processing was conducted from specimens inspected to
tissue lesions with routine protocol and histopathological changes of livers
were examined under light microscopy. RESULTS:
Macroscopic investigation of 281 cases showed 90 livers (32.02%) with gross lesions.
In histopathological examination, there were 83 cases (29.53%) with
hydatidosis, 3 cases (1.07%) with fasciolosis, 2 cases (0.71%) with
perihepatitis and 2 cases (0.71%) with lipidosis.                                                             
                 CONCLUSIONS:
Based on the results of this study, the most frequent liver lesion in cattle
slaughtered in Zabol City was hydatidosis indicating the active life cycle of Echinococcus
guanulosus
and the outbreak of this parasitic disease in dogs and other
carnivores in Sistan region

Abstract [Persian]

زمینه مطالعه: ضایعات کبدی در گاو نه تنها باعث اثرات منفی بر صنعت پرورش گاو می‌گردد، بلکه سبب افت تولید پروتئین حیوانی و خصوصاً به خطر افتادن سلامت مصرف کنندگان می شود. هدف: این مطالعه با هدف بررسی ماکروسکوپیک و هیستوپاتولوژیک ضایعات کبدی در گاوهای کشتار شده در شهرستان زابل انجام گرفت. روش کار: کبد 281 رأس گاو کشتار شده در کشتارگاه صنعتی شهرستان زابل از فروردین تا شهریور سال 1394 جهت ارزیابی ظاهری و میکروسکوپی جمع‌آوری شد. مراحل آماده‌سازی بافتی از نمونه‌های مشکوک به ضایعات بافتی با روش متداول انجام گرفت و تغییرات هیستوپاتولوژیک کبدها توسط میکروسکوپ نوری بررسی شد. نتایج: ارزیابی ماکروسکوپیک 281 نمونه، نشان دهنده وجود 90 کبد (32.02%) دچار ضایعات ظاهری بود. در بررسی هیستوپاتولوژیک، 83 مورد (29.53%) مبتلا به هیداتیدوزیس، 3 مورد (1.07%) مبتلا به فاسیولوزیس، 2 مورد (0.71%) مبتلا به پری هپاتیت و 2 مورد (0.71%) مبتلا به لیپیدوزیس بودند. نتیجه گیری نهایی: بر اساس نتایج این مطالعه شایع‌ترین ضایعه کبدی در گاوهای کشتارشده در شهرستان زابل هیداتیدوزیس بود که نشان دهنده چرخه زندگی فعال انگل اکینوکوکوس گرانولوسوس و شیوع این بیماری انگلی در سگ‌ها و سایر گوشتخواران منطقه سیستان می‌باشد.
