摘　　要：目的探讨中国台湾孔头舌虫新种(Porocephalustaiwanasp.nov.)的形态与致病特征及新病种的病原学诊断方法。方法用患者稀便用粪便沉淀浓集法收集粪中若虫鉴定虫种,并结合临床资料作统计分析,以确定此新种所致疾病的临床特征。结果发现了舌形虫病的一种致病新种,即为台湾孔头舌虫,其所致的疾病称台湾孔头舌虫病。根据本例的发现,提出传统的内脏舌形虫病可分为2个亚型,成囊亚型和脱囊亚型。根据其病理学特征,本病例属于脱囊型内脏舌形虫病。结论描述了台湾孔头舌虫新种,其所致的台湾孔头舌虫病属于一种新型脱囊亚型性内脏舌形虫病。Objective To describe the morphological characteristics of Porocephalus taiwana sp. nov., discuss its pathogenic features and the method of etiological diagnosis of the new disease. Methods Fecal sedimentation concentration was used to collect nymphs from the patient's watery stool for species identification. Clinical information was collected for determining the pathogenic features of the new infection. Results A new pathogenic pentastomid Porocephalus taiwana sp. nov. is discovered and a new disease-porocephaliasis taiwana-is nominated. With the findings from this case it is proposed that the traditional visceral pentastomiasis should be divided into two subtypes, Encystic and Excystic. According to the pathological features, this case belongs to the excystic visceral pentastomiasis. Conclusion Porocephalus taiwana sp. nov. is a new pathogenic pentastomid infecting humans. Porocephaliais taiwana belongs to a novel type (excystic) of visceral pentastomiasis.
