Deciphering the global genetic structure of Spirometra mansoni and S. erinaceieuropaei based on 28S ribosomal RNA: Insights into taxonomical revaluation and population dynamics.

ABSTRACT: The latest taxonomy recognizes two Spirometra species in Asia: S. mansoni and S. asiana, with the former exhibiting a global distribution. The isolates analyzed in this study were classified accordingly, and a S. mansoni isolate from India was identified using morphology, Polymerase Chain Reaction (PCR), sequencing, and phylogenetics. Furthermore, a global analysis of genetic diversity, haplotype network structure, and population dynamics of Spirometra spp. was conducted using the 28S rRNA marker. Phylogenetic analysis of Spirometra sequences (n = 104) revealed two distinct clades: a larger clade with Asian (China, Korea, and India) and African (Egypt) sequences (reclassified as S. mansoni) and a smaller clade with European (Latvia and Finland) sequences (true S. erinaceieuropaei).
