The investigations covered 54 subsequent generations of Hymenolepis diminuta WMS "strain" obtained through the administration of 6 cysticercoids of tapeworm to Wistar strain rats and WAG alb. rats. The number of tapeworms at 2.5 months after the infection of rats ranged from 3 to 6, on the average 5.2. Taking into consideration the most important type 1p2a (one testis on the poral side and two testes on the aporal side), 0p3a, 1p3a and 2p1a proglottids a significant differences was found in the distribution of the numerousity of type 1p3a proglottids (P < 0.05). This indicates a possibility of an unguided change of the number of proglottids of this type in a period covering 54 subsequent H. diminuta generations bred in laboratory conditions.
研究涵盖了通过给Wistar品系大鼠和WAG白化大鼠投喂6个微小膜壳绦虫囊尾蚴而获得的54代微小膜壳绦虫WMS“品系”。大鼠感染后2.5个月时绦虫数量在3至6条之间，平均为5.2条。考虑到最重要的1p2a型（poral侧有一个睾丸，aporal侧有两个睾丸）、0p3a型、1p3a型和2p1a型节片，发现1p3a型节片数量分布存在显著差异（P < 0.05）。这表明在实验室条件下培育的54代连续微小膜壳绦虫中，这种类型节片数量可能会发生无规律变化。
