%X 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.
