对西班牙卡斯蒂利亚-里昂地区3年来宰杀的牛进行了自然副血吸虫病的流行和病原学调查。阳性动物总患病率为6.20%。每头动物的寄生虫量为8~8005只(中位数为144)，其中瘤胃心房的寄生虫量最高，而瘤胃背囊的寄生虫量最低。患病率和寄生虫负担随年龄增长而增加，而集约化管理下牛的这些参数较低。通过形态解剖学、组织学和分子生物学方法在所研究动物中鉴定出的唯一一种副血吸虫科。(C)2013爱思唯尔B.V.保留所有权利。
The prevalence and aetiology of natural paramphistomosis was investigated in cattle slaughtered in the Castilla y Leon region (Spain) over a 3 year-period. The overall prevalence of positive animals was 6.20%. The parasite burden per animal ranged from 8 to 8005 (median = 144) and the ruminal atrium had the highest parasite burden whereas the ruminal dorsal sac the lowest. The prevalence and parasite burden increased with age while these parameters were lower in cattle under intensive management. Calicophoron daubneyi was the only Paramphistomidae species identified using morphoanatomical, histological and molecular methods in the studied animals. (C) 2013 Elsevier B.V. All rights reserved.
