Abstract:Objective To further investigate the biological characteristics of Taenia pisiformis Sichuan strain, as well as to provide basic knowledge for future prevention and control of Cysticercus pisiformis infection. Methods Eight rabbits were infected with T. pisiformis eggs and then killed for larvae collection on day 60 post-infection (PI). Meanwhile, the number and location of C. pisiformis were determined. Subsequently, five dogs were infected with C. pisiformis under standard experimental conditions. The time of first discharged gravid proglottids, the number of daily evacuated gravid prolottids and the duration of gravid proglottids evacuation were recorded. Furthermore, fifty-five gravid proglottids were selected to examine the numbers and sizes of eggs in each gravid proglottid using microscope. Microscopy was also conducted to observe the hatching process of eggs activated by 1% sodium hypochlorite solution. Methods The infected dogs were first observed evacuating gravid progottids on day 39 PI, 43 PI, 45 PI, 50 PI and 57 PI, respectively. The largest number of gravid proglottids evacuated per day was 158. Representatively, the amount of eggs within a single gravid proglottid ranged from 60 to 26 480, with an average of 3372, while the egg size was (41.32 ± 4.53) μm×(36.23 ± 4.92) μm. Egg hatching took about 4 to 5 min in vitro. In rabbits, C. pisiformis mainly parasitized great omentum and mesentery. Conclusion The discharge of gravid proglottid by mature T. pisiformis lasted for a considerable time, and the gravid proglottid releasing a significant number of eggs, which could cause great environmental contamination and increase the risk of infection in intermediate host.
