Resumen
Human polycystic echinococcosis is a parasitic infection caused by the larval stage of Echinococcus vogeli, which occurs in
rural areas of Central and South America. Until now, little information on the genetic variability of E. vogeli is available.
Here, 32 samples from human-excised E. vogeli cysts had a 396-bp sequence of the mitochondrial cytochrome oxidase I (COI)
gene sequenced and compared to another 17 COI sequences representing nine Echinococcus species. A Bayesian COI tree
revealed that all E. vogeli sequences formed a monophyletic and well-supported clade with an E. vogeli reference sequence.
The occurrence of geographically restricted E. vogeli COI haplotypes suggests retention of ancestral polymorphisms with little
migration in Acre, Brazil.
