Case of the Week 614

 This week's case is from my lab, with the photos taken by our excellent technical specialist, Heather Morris. The following structures were seen in lung cyst fluid. Identification?

These are beautiful pictures of protoscolices and hooks of Echinococcus granulosus complex parasites. We now know that human infection is caused by several species and genotypes within what was once thought of as a single species.

Beautiful hydatid cysts. The hooklets are clearly visible in the protoscolex and in the sand. For sure at this stage we can only identify as Echinococcus granulosis sensu lato.

Hydatid Cyst, from Echinococcus granulosis

echinococcus sp.....if not a case of versteria.... Up north there has been more cases of multilocularis or canadiensis so I wonder if it could be that instead of the old chestnut, granulosus.
lovely pictures
