The lentil lectin glycoprotein enzyme-linked immunoelectrotransfer blot (LLGP EITB, reported sensitivity 99% and specificity 100%) is used as a serologic marker of exposure to in pigs. However, only a limited number of parasites have been evaluated for cross reactivity. Pigs may host other related cestode infections, including which have not been formally evaluated for cross-reactions. We investigated a corral in Tumbes, Peru, a region where a cysticercosis elimination demonstration project was completed in 2012. In this corral, 14/19 (73.7%) 6–8-week-old piglets were reactive to GP50 on LLGP EITB, and all had circulating sp. antigens. From eight necropsied piglets; four were infected with metacestodes whereas none had evidence of infection. Two resident dogs were subsequently confirmed to have taeniasis. These results suggest GP50 cross-reactivity in infected pigs, although controlled experimental infection is needed to confirm this hypothesis.
