Additional human cases of Diplogonoporus grandis

In this paper, three human cases of Diplogonoporus grandis infection were recorded as the 56, 57 and 58 cases in Japan. These fragmented strobilae of the tapeworm were spontaneously discharged from a 33 years old female and 40 and 38 years old males living in Nagasaki Prefecture. After treatment with Kamala (10g), a strobila with scolex was expelled from the 1st patient. The shape of the scolex was similar to the 14th case in Japan (Koga 1938) and the other morphological features were comparable to the characteristics of D. grandis. The length of the strobila was 154 cm in the 1st case, 468 cm in the 2nd and 458 cm in the 3rd one, respectively. The 2nd and 3rd specimens obtained lacked the scolex and terminal segment. Detailed morphological study was made on the proglottides. The proglottides obtained from the 1st and 2nd cases were immature and no genital organ was demonstrated by the external observation. However, they were identified as the tape-worm belonging to genus, Diplogonoporus by the charasteristically short and broad proglottides measuring about 0.57-0.94 mm in length by 11.5-13.5 mm in width, and by the double set of genital rudiments in each proglottid which was recognized in the horizontal and transverse or sagittal sections. The proglottid obtained from the 3rd case was mature and the double set of genital organ could be demonstrated in each segment. The proglottid measured was 0.34-0.49 mm in length by 16.0-18.0 mm in width. The uterus in each proglottid contained eggs in the transverse or sagittal sections
