[Grand Round] First human infection and management of Versteria rafei infection restricted to the liver with phylogenetic analysis in the context of known cases

A recently described cestode genus, Versteria, has been implicated in disseminated human disease in North America. We report the first known case of infection with a recently reported species, Versteria rafei, localised to the liver with attempted surgical resection. Through review of other patients known to be infected with this parasite, we established that this is a rare zoonotic infection involving contact with minks and mustelids. Although Versteria belongs to the same family as Echinococcus, there are several important differences.
