[A human infection of the cestode, Diphyllobothrium nihonkaiense Yamane et al., 1986].
A mature cestode, obtained from a 49-year-old man in Fukuoka, southern Japan, was examined. The worm was about 70 cm in length without scolex. The largest segment was 1.8 x 0.8 cm. Cirrus sac lay at an obtuse angle (about 150 degrees) to seminal vesicle. The eggs were 62.06 +/- 9.40 x 43.33 +/- 6.43 microns and the shell thickness 1.0-1.5 microns, with round, shallow and sparsely distributed surface pits ranging 0.8-2.0 microns in diameter. The above features suggested that this worm was identified as the cestode, Diphyllobothrium nihonkaiense.
