Abstract

<abstract abstract-type="normal"> <title>Abstract</title> <p>Cysticercosis is caused by infections with embryonated eggs of the tapeworm <italic>Taenia pisiformis</italic>. Knowledge of the genetic characteristics of <italic>T. pisiformis</italic> could be applied to study the epidemiology and transmission of this parasite. In this study, 61 isolates of intraperitoneal cysticerci from eight geographically distinct regions in Sichuan province, China, were subjected to a molecular analysis in order to determine their intra-regional genetic characteristics. Partial sequences of the mitochondrial cytochrome <italic>c</italic> oxidase subunit I (<italic>cox1</italic>, 1427 bp) and NADH dehydrogenase 1 (<italic>nad1</italic>, 738 bp) were concatenated. Five haplotypes were identified, and 89.04% of total genetic variation was found in collections of <italic>T. pisiformis</italic> isolates from a single region. According to the phylogenetic reconstruction, the <italic>T. pisiformis</italic> isolates from eight regions did not form geographical clusters. Our study highlights the genetic characteristics of <italic>T.</italic><italic>pisiformis</italic> with the aim of accelerating the genetic research and control of cysticercosis.</p> </abstract>
