甘肃省发现2例猪泡型棘球蚴病病例

Two Cases of Porcine Echinococcosis Multilocularis Found in Gansu Province

泡型棘球病(echinococcosis multilocularis)由多房棘球蚴(Echinococcus multilocularis)寄生于野生啮齿类等动物的肝脏引起,绵羊、牦牛、猪等家畜感染病例较为少见,人可被感染。2023年屠宰检疫时,在甘肃省临洮县一散养户圈养的28头猪中,发现2例猪泡型棘球蚴病病例。患猪生前体重明显小于其他同龄猪;虫体寄生于患猪腰椎两侧腹壁,临床表现多个囊泡;囊液前期为淡黄色,后期为黑红色。怀疑患猪因食入犬排出的多房棘球绦虫虫卵而感染。本病例的发现及确诊对甘肃省猪泡型棘球蚴病的防控具有预警和指导作用。

Echinococcosis multilocularis is caused by Echinococcus multilocularis parasitizing in livers of wild rodents,which occasionally infects sheep,yaks,human and pigs.2 of 28 pigs in a free-range household in Lintao County,Gansu Province were found to be infected with Echinococcus multilocularis after be slaughtered,and the weight of the infected live pigs was obviously less than that of others of the same age.The parasites parasitized on the abdominal walls of both sides of the lumbar spine,with clinical symptom of multiple vesicles,the cyst fluid was light yellow at early stage,then turned to black red later.Pigs suffered from the disease through ingesting Echinococcus multilocularis eggs excreted by dogs.Considering few clinical cases of pigs infected with Echinococcosis multilocularis,the confirmed cases were considered as an early warning for prevention and control of the disease in Gansu Province.
