ABSTRACTInformation on age-based Taenia soliumtaeniasis prevalence is crucial for control of cysticercosis. T. soliumtaeniasis prevalence was determined for a village in Liangshan Prefecture, Sichuan Province, China that was co-endemic for T. solium, Taenia saginata asiatica, and Taenia saginata. Individuals who were Taeniaegg-positive by stool microscopy and/or expelled tapeworms or proglottids post-treatment were diagnosed as having taeniasis. Infecting species was identified via multiplex PCR on tapeworm specimens or coproPCR followed by sequencing. In addition, initial stool samples from 10 children with taeniasis suspected of having spontaneous expulsion of tapeworms within the period between diagnosis and treatment were subject to species confirmation via coproPCR and sequencing. Of the 389 study subjects, 194 (49.9%) were diagnosed with taeniasis. Children (< 16 years of age) had a higher T. soliumtaeniasis prevalence (8.8%) than older individuals (2.5%) (P = 0.0127). Molecular analysis of initial stool samples from 7 of 10 children suspected of spontaneously passing tapeworms indicated 6 infections due to T. soliumand 1 infection due to T. saginata. This study found that young children had a higher T. soliumtaeniasis prevalence than older individuals, providing additional support for the belief that adult T. soliumlikely has a relatively short lifespan compared to other Taeniaspecies with human definitive hosts. |
