The prevalence of dicrocoeliosis was estimated by the examination of liver of slaughtered goats (n = 228) brought from two major goat rearing regions (Kandi and R.S. Pura) of Jammu province of India. Dicrocoelium dendriticum was found in 18.9 % of the goats, with mean fluke count (±SEM) of 24.9 ± 4.4 (ranged from 0 to 478). A significant seasonal variation (p < 0.01) was recorded with maximum prevalence in winter (28.9 %), followed by post-rainy (22.2 %) and minimum in rainy season (9.4 %). The highest fluke count was observed in January (47.8 ± 24.6) while none of the examined animals was found positive in May and June. The origin of the goats had a significant association (p < 0.0001) with prevalence rates and the goats from Kandi region (27.3 %) showed higher prevalence rates as compare to R.S. Pura (8.0 %). However, the age and sex had no significant effect on the prevalence of dicrocoeliosis in goats. The histopathological examination of infected livers revealed excessive thickening and proliferation of bile duct glandular epithelium with inflammatory exudates. Also, intense mononuclear cells infiltration with young fibroblasts was observed in the surroundings of bile ducts in portal areas along with atrophy of hepatocytes.
通过检查从印度查谟省两个主要养羊地区（坎迪和拉杰普尔）运来的屠宰山羊（n = 228）的肝脏，估计了双腔吸虫病的流行情况。在18.9%的山羊中发现了枝双腔吸虫，平均吸虫计数（±标准误）为24.9±4.4（范围为0至478）。记录到显著的季节变化（p < 0.01），冬季患病率最高（28.9%），其次是雨后（22.2%），雨季最低（9.4%）。1月份观察到最高的吸虫计数（47.8±24.6），而在5月和6月检查的动物中未发现阳性。山羊的来源与患病率有显著关联（p < 0.0001），坎迪地区的山羊（27.3%）患病率高于拉杰普尔地区（8.0%）。然而，年龄和性别对山羊双腔吸虫病的患病率没有显著影响。对受感染肝脏的组织病理学检查显示胆管腺上皮过度增厚和增殖，并伴有炎性渗出物。此外，在门管区胆管周围观察到强烈的单核细胞浸润和年轻成纤维细胞，同时肝细胞萎缩。
