飼い猫に寄生した有線条虫Mesocestoides sp.の1症例

A 2-year-old domestic cat discharged 2 small cestode segments (1mm × 1mm) into the stool on 16th in March, 1993. On the next day, 4 cestode strobilae without scolex were obtained from this cat by administration of praziquantel (30mg/kg). Strobilae measured approximately 60-86mm in length and 1mm in maximum width. In each immature segment, the number of testes was more than 60. A paruterus measuring 316-473μm × 316-371μm was situated at the rear central part of each gravid segment. The eggs (32 × 24μm) in the paruterus contained oncosphers. These Mesocestoides Cestoda were not identified as M.lineatus or M. literatus for lack of their scoleces.
