摘　　要：首次在中国报道1例由长颈囊尾蚴(Cysticercus longicollis)引起的5岁雄性圈养环尾狐猴(Lemur catta)皮下囊尾蚴病,患病动物表现为明显的臀部囊肿,但无其他异常体征。该病例就诊于四川农业大学第二教学动物医院。在就诊期间,采用细针穿刺对囊肿内容物进行形态学检查。结果显示:囊肿内含有大量囊尾蚴,典型囊尾蚴呈椭圆形,具有长而可伸缩的颈部和单个头节,头节上有4个吸盘和16个(单排)小钩。通过对囊尾蚴DNA进行nad1和cox1基因扩增及测序,进一步确定该囊尾蚴为肥头绦虫(Taenia crassiceps)的幼虫形态,即长颈囊尾蚴,研究结果可为该寄生虫在国内的流行病学调查及防控提供参考。A case of subcutaneous cysticercosis caused by Cysticercus longicollis in a five-year-old captive male ring-tailed lemur(Lemur catta)was first reported in China.The infected animal showed obvious gluteal cysts,but no other abnormal signs.The case was treated in the Second Teaching Animal Hospital of Sichuan Agricultural University.During the consultation,fine needle aspi⁃ration was used to perform morphological examination of the cyst contents.The results showed that the cyst contained a large number of cysticerci.The typical cysticerci were oval in shape,with a long and retractable neck and a single scolex,on which there were four suckers and 16 hooks(in a single row).The cysticerci were subsequently confirmed to be the lar⁃val form of Taenia crassiceps,i.e.,Cysticercus longicollis,by the amplification and sequencing of the nad1 and cox1 genes in cysticerci DNA.The results can provide a reference for epidemiological investigation and prevention and control of this parasite in China.
