Abstract：
A 35-year-old man with fever and diarrhea visited our hospital because of white string-like fecal excretion. Based on a morphological examination of the excreted object, a Diphyllobothrium infection was suspected. Additionally, Gram staining of a fecal sample revealed Campylobacter infection. After the intraduodenal administration of meglumine/diatrizoate sodium, the tapeworm was excreted. A polymerase chain reaction-based DNA sequence analysis demonstrated that the tapeworm excreted in this case was Diphyllobothrium nihonkaiensis. This report presents a rare case of coinfection with Diphyllobothrium nihonkaiensis and Campylobacter jejuni. Therefore, it is important to consider the coexistence of other intestinal infections when diagnosing parasitic infections in patients with fever.
摘要：
一名35岁的发烧和腹泻的男子因粪便排泄物呈白色细绳状而来我院就诊。根据对排泄物的形态学检查，怀疑有双叶虫感染。此外,粪便样品的革兰氏染色显示弯曲杆菌感染。十二指肠内施用葡甲胺/泛影酸钠后，条虫被排泄了.基于聚合酶链反应的DNA序列分析表明，在这种情况下排泄的tape虫是日本二叶虫。本报告介绍了一例罕见的与日本双喉杆菌和空肠弯曲杆菌同时感染的病例。因此,在诊断发热患者的寄生虫感染时，重要的是要考虑其他肠道感染的共存。
