This is a report of Ternidens deminutus infection in a 33 year old Thai female who was admitted to the hospital because of abdominal pain and a right lower quadrant mass. Exploratory laparotomy revealed an omental mass with attached terminal ileum. Resection of the mass together with the terminal ileum and the right sided colon was performed. Pathologically, the omental mass was an abscess with an immature male Ternidens deminutus identified. The parasite usually is found in the intestine of primates in Africa and Asia. Human infection occurs when food contaminated with infective filariform larvae is ingested. The larvae molt in the intestinal wall and become adults. They pass eggs in feces. Eggs in contaminated soil hatch and become rhabditiform larvae and then infective filariform larvae.
这是一份关于一名33岁泰国女性感染微小齿线虫的报告。该女性因腹痛和右下腹肿块入院。剖腹探查发现一个附着于回肠末端的网膜肿块。对该肿块连同回肠末端和右侧结肠进行了切除。病理检查显示，网膜肿块为脓肿，其中发现了一条未成熟的雄性微小齿线虫。这种寄生虫通常存在于非洲和亚洲灵长类动物的肠道中。当摄入被感染性丝状幼虫污染的食物时，人类就会被感染。幼虫在肠壁内蜕皮并发育为成虫。它们通过粪便排出虫卵。受污染土壤中的虫卵孵化后变成杆状幼虫，进而发育为感染性丝状幼虫。
